How to Speed Up Windows 11 — 15 Methods That Actually Work

Every program that launches automatically when Windows starts consumes CPU, RAM, and disk I/O during boot — even programs you never actually open. Over time, software installers quietly add themselves to the startup list. It is common for a two-year-old PC to have 12 or more programs launching in the background before you have even touched the keyboard. This is the single most common reason Windows 11 feels slow immediately after login, and fixing it takes under five minutes.

• Right-click the taskbar and select Task Manager, or press Ctrl + Shift + Esc
• Click the Startup apps tab in the left sidebar
• Click the Startup impact column header to sort by impact (High, Medium, Low)
• Right-click any program with High or Medium impact that you do not need immediately on boot
• Select Disable — the program still installs and works normally, it just will not launch automatically at startup
• Safe to disable: Spotify, Discord, Teams (if not used for work), OneDrive sync, Zoom, Skype, Steam, Adobe updaters, any game launcher
• Keep enabled: your antivirus, audio drivers, graphics card software (NVIDIA/AMD), and anything labeled as a Windows system process
• Restart your PC and measure the boot time difference

Bloatware refers to pre-installed software that came with your PC and that you have likely never used: manufacturer utilities, trial antivirus suites, third-party toolbars, promotional apps, and Windows-bundled games. Even when you are not actively using these programs, many of them run background processes, check for updates, and occupy hundreds of megabytes of disk space. Removing them is one of the fastest ways to make Windows 11 faster and recover storage space simultaneously. This is particularly effective on brand-new or recently purchased PCs from manufacturers like HP, Lenovo, and Dell, which often ship with 15–25 pre-installed apps.

• Press Win + I to open Settings
• Navigate to Apps > Installed apps
• Sort by Size to identify the largest programs first
• Click the three-dot menu next to any program you do not use and select Uninstall
• Common bloatware targets: McAfee or Norton trial (if you use Windows Security instead), WildTangent Games, Candy Crush, Facebook, Disney+, HP Support Assistant (if not on HP), Lenovo Vantage background services, Dell SupportAssist unless needed, any app from your carrier if it is a cellular laptop
• To remove stubborn built-in Windows apps, open PowerShell as Administrator and use: Get-AppxPackage *AppName* | Remove-AppxPackage
• After uninstalling, restart the PC to allow all background services to fully stop

Windows 11 ships with a set of animations, transparency effects, and shadow rendering designed to look polished on high-end hardware. On systems with integrated graphics, older CPUs, or 4–8 GB of RAM, these effects consume measurable GPU and CPU resources. Switching to the "Best performance" preset eliminates all animations and delivers a noticeably snappier feel — especially when opening and closing windows, switching apps, and navigating menus. This tweak to speed up Windows 11 is particularly effective on low-spec laptops and older desktops where every resource counts.

• Press Win + R, type sysdm.cpl, and press Enter to open System Properties
• Click the Advanced tab
• Under the Performance section, click Settings
• Select Adjust for best performance to disable all visual effects at once
• Alternatively, choose Custom and keep only: "Smooth edges of screen fonts" and "Show thumbnails instead of icons" for a balance between appearance and speed
• Click Apply, then OK
• You can also separately disable transparency: go to Settings > Personalization > Colors and turn off Transparency effects
• Also consider: go to Settings > Accessibility > Visual effects and turn off Animation effects

Windows accumulates a surprising amount of junk over time: Windows Update residue, temporary files from software installations, browser cache leftovers, thumbnail database files, error log archives, and delivery optimization files from updates downloaded for other devices. When your drive fills up past 85–90% capacity, Windows has nowhere to write temporary data and performance degrades sharply — a hard drive or SSD with less than 10% free space will cause noticeable Windows 11 slowness regardless of any other optimization you apply. Disk Cleanup (cleanmgr) is the built-in Microsoft tool that safely removes all of this accumulated waste.

• Press Win + R, type cleanmgr, and press Enter
• Select the drive to clean (usually C:) and click OK
• Wait for the scan to complete, then review the list of items found
• Check all available boxes, then click Clean up system files for a deeper administrative scan (requires confirmation)
• Select the drive again and ensure you also check: Windows Update Cleanup, Previous Windows installations (if available), Delivery Optimization Files, and Temporary Internet Files
• Click OK and then Delete Files to confirm the deletion
• For a more modern interface with the same functionality, open Settings > System > Storage > Temporary files

On a traditional spinning hard drive (HDD), files become fragmented over time as they are written to non-contiguous sectors across the disk. The drive's read head must physically move to multiple locations to reassemble a single file, which dramatically slows read speeds. On an SSD, fragmentation is not a performance concern because there is no physical movement — but running the Optimize Drives tool sends TRIM commands that tell the SSD which data blocks are no longer needed, allowing the drive's controller to pre-erase them and maintain write performance over time. Windows 11 schedules this automatically weekly, but it is worth verifying the schedule is active and running a manual pass if needed.

• Press Win + S and search for Defragment and Optimize Drives, then open it
• Select your C: drive and check the Media type column — it will show Hard disk drive or Solid state drive
• If it is an HDD: check the Current status column. If fragmentation is above 5%, click Optimize
• If it is an SSD: the tool runs TRIM instead of defragmenting. Click Optimize — it completes in seconds and maintains long-term drive health
• Click Change settings and confirm that Run on a schedule is checked and set to Weekly
• Important: never use third-party "defrag" tools on SSDs — they cause unnecessary write wear with zero performance benefit

The Windows Search service continuously monitors your files and builds a searchable database so that Start menu searches return results instantly. On fast NVMe SSDs with modern CPUs, the overhead is negligible. However, on older HDDs or low-powered budget laptops, the indexer's constant background disk activity is a persistent drag on performance — especially in the first 30–60 minutes after boot when the indexer is most active rebuilding its database. If you rarely use Windows Search to locate files (preferring to navigate through File Explorer instead), disabling the indexer reclaims those resources entirely. This is one of the most underrated tweaks to speed up Windows 11 on older hardware.

• Press Win + R, type services.msc, and press Enter to open the Services window
• Scroll down the list and locate Windows Search
• Right-click it and select Properties
• Change the Startup type dropdown from Automatic (Delayed Start) to Disabled
• Click the Stop button under Service status to halt it immediately without restarting
• Click Apply, then OK
• Note the trade-off: File Explorer searches will now perform a real-time scan rather than querying the index, which is slower but still acceptable on SSDs. Start menu app searches are not affected.
• To re-enable search indexing in the future, simply return to services.msc, set Windows Search back to Automatic (Delayed Start), and click Start

Outdated or corrupted drivers are a surprisingly common cause of Windows 11 running slow — yet they are frequently overlooked because users assume Windows Update handles everything automatically. The graphics driver in particular — whether Intel integrated, NVIDIA dedicated, or AMD — is directly responsible for how smoothly the entire Windows 11 interface renders. An out-of-date GPU driver can cause stuttering, unexpectedly high CPU usage during basic desktop tasks, and slow video playback even in the browser. Outdated chipset and storage drivers can also limit how fast your SSD or HDD communicates with the CPU, reducing effective disk throughput even on fast drives.

• Right-click the Start button and select Device Manager
• Look for any device with a yellow warning triangle — these have driver problems and should be addressed first
• Expand Display adapters and right-click your GPU to choose Update driver > Search automatically for drivers
• For best results with NVIDIA GPUs, download the latest driver directly from nvidia.com/drivers and use the "Clean install" option
• For AMD GPUs, download from amd.com/support and install via AMD Adrenalin software
• For Intel integrated graphics, use the Intel Driver & Support Assistant from intel.com/dsa
• Also update: Network Adapter drivers, Chipset drivers (from your motherboard manufacturer's support page), and Audio drivers
• Restart after installing any major driver update

Malware is one of the leading causes of a Windows 11 PC running slow — yet it is frequently overlooked because users assume their antivirus would have caught anything dangerous. Cryptocurrency miners, adware, and spyware routinely bypass real-time protection and run silently in the background, consuming 20–80% of your CPU and RAM continuously. If Task Manager shows consistently high resource usage by processes with unfamiliar names, or your PC runs hot and loud even when you have nothing open, malware is the very likely culprit. Running two complementary tools catches nearly all known threats including the ones that evade a single scanner.

• Press Win + I, navigate to Privacy & security > Windows Security
• Click Virus & threat protection
• Click Scan options and select Full scan, then click Scan now — this checks every file on your drive and takes 20–60 minutes
• While the scan runs, download Malwarebytes Free from malwarebytes.com/free as a complementary second-opinion scanner
• After Windows Security completes its scan, run a Malwarebytes full scan — it specializes in adware, spyware, and PUPs that traditional antivirus engines commonly miss
• Remove all threats found by both tools and restart the PC
• If you still suspect malware after both scans, boot into Safe Mode (hold Shift, click Restart, then go to Troubleshoot > Advanced options > Startup Settings > press F4) and run both scans again from Safe Mode where most malware cannot defend itself

When your physical RAM is full, Windows uses a reserved portion of your hard drive or SSD as a temporary overflow area called the pagefile — also known as virtual memory. By default, Windows 11 manages the pagefile size automatically, but on systems with limited RAM (4–8 GB), the automatic sizing can be too conservative, causing Windows to run out of virtual memory under load and slow to a crawl with a freeze that can last 30–120 seconds. Manually setting a larger fixed pagefile ensures Windows always has ample overflow space. While virtual memory is far slower than real RAM, it prevents the catastrophic freezes that occur when physical memory is completely exhausted during multitasking or heavy browser use.

• Press Win + R, type sysdm.cpl, and press Enter to open System Properties
• Go to the Advanced tab and click Settings under Performance
• Click the Advanced tab in the Performance Options dialog
• Under Virtual memory, click Change
• Uncheck Automatically manage paging file size for all drives
• Select your C: drive and choose Custom size
• Set Initial size to 1.5x your installed RAM in MB — for example, 12,288 MB for 8 GB RAM
• Set Maximum size to 3x your installed RAM in MB — for example, 24,576 MB for 8 GB RAM
• Click Set, then OK, then restart the computer for the change to take effect

Many Windows 11 apps continue running in the background even after you close the window, checking for notifications, syncing data, refreshing live tile content, and downloading updates. While this behavior is useful for apps like Mail and Calendar that need to stay current, it is completely unnecessary for apps you use infrequently. Each background-active app contributes to the overall drain on CPU, RAM, and battery. Selectively disabling background activity for rarely-used apps is a low-risk tweak that helps make Windows 11 faster without affecting your core workflow, and makes a particularly noticeable difference on laptops where battery life is also a concern alongside speed.

• Press Win + I to open Settings
• Navigate to Apps > Installed apps
• Find an app you want to restrict, click its three-dot menu, and select Advanced options
• Under Background apps permissions, change the setting from Always to Power optimized or Never
• Repeat for apps you rarely use: Maps, Weather, News, Money, Xbox app (if not a gamer), Feedback Hub, Cortana, Microsoft Tips, Office background services you do not need
• For a global approach, navigate to Settings > System > Power > Battery saver and enable it to automatically restrict background activity when on battery
• Note: Do not set Mail, Calendar, or Teams to Never if you rely on them for notifications — Power optimized is sufficient for these

Storage Sense is Windows 11's built-in automatic disk maintenance feature. When enabled, it periodically deletes temporary files, empties the Recycle Bin automatically, removes files from the Downloads folder that have not been opened in a configurable period, and cleans up locally-cached OneDrive files you have not accessed recently. Unlike Disk Cleanup which must be run manually, Storage Sense works continuously in the background to ensure your drive never quietly fills up and starts degrading performance. It is a low-effort, permanent solution to a problem that silently affects many users who forget to perform manual maintenance — and it directly prevents the kind of gradual Windows 11 slowdown that sneaks up on users over months.

• Press Win + I and go to System > Storage
• Toggle Storage Sense to On
• Click on the Storage Sense label to open its configuration settings
• Set Run Storage Sense to Every week for proactive maintenance
• Under Temporary Files, ensure Delete temporary files that my apps aren't using is checked
• Set the Recycle Bin deletion timer to 30 days
• Set Downloads folder cleanup to 60 days — or Never if you actively store important files in Downloads
• Click Run Storage Sense now for an immediate first cleanup pass

If your computer currently has a traditional spinning hard disk drive (HDD), upgrading to a solid state drive (SSD) is the single most impactful thing you can do to speed up Windows 11. No software tweak comes remotely close. A modern SATA SSD reads data at 500–560 MB/s compared to an HDD's 80–120 MB/s — roughly a 5x improvement at the storage level. An NVMe M.2 SSD pushes 3,000–7,000 MB/s — up to 60x faster than an HDD in raw sequential reads. In practice, this means your Windows 11 PC boots in 10–15 seconds instead of 60–90 seconds, applications launch in 1–2 seconds instead of 10–20 seconds, and the system never freezes while loading large files.

The most common scenario our technicians encounter is a 5–8 year old laptop with 8 GB of RAM and a 5400 RPM HDD where the owner believes the machine is "dead" and ready for recycling. After a $90 SSD swap and a Windows reinstall, that same computer performs like a mid-range modern laptop — all for a fraction of the cost of a new machine. An SSD upgrade extends the functional life of a PC by 3–5 years.

• First, determine whether your PC has an M.2 slot (for NVMe SSD) or only a 2.5" SATA bay — check your laptop/desktop manufacturer's specifications page or use CPU-Z to identify your motherboard model
• For laptops with only a 2.5" SATA bay: buy a 2.5" SATA SSD — Samsung 870 EVO, Crucial MX500, or Kingston A400 are reliable choices at $60–$90 CAD for 500 GB
• For desktops or laptops with an M.2 NVMe slot: buy an NVMe M.2 SSD — Samsung 980, WD Blue SN580, or Crucial P3 at $70–$120 CAD for 500 GB–1 TB
• To migrate your existing Windows installation to the new SSD without reinstalling: download Macrium Reflect Free and use its "Clone this disk" function to copy everything over while Windows is running
• Alternatively (and for the cleanest result): install the SSD, do a fresh Windows 11 install, then restore your personal files from backup
• After installation, open Task Manager > Performance > Disk and confirm the drive type shows as SSD
• In BIOS/UEFI, verify that the storage controller is set to AHCI mode (not IDE mode) for maximum SSD performance — AHCI enables the NCQ feature that SSDs depend on for peak speed

RAM (Random Access Memory) is your computer's short-term working memory. When you have multiple applications open, Windows 11 stores the active data for each in RAM for instant access. If RAM fills up, Windows begins using the pagefile on the hard drive or SSD as overflow — which is dramatically slower even on the fastest NVMe drives. Windows 11 with a modern browser, an Office document open, and a few background processes running can easily consume 6–8 GB of RAM. A system with only 8 GB total runs with very little headroom, causing frequent slowdowns whenever you open another browser tab or switch applications. Adding RAM directly addresses the root cause of this category of Windows 11 slowness.

• First, verify the problem: open Task Manager > Performance > Memory. If you consistently see over 75% usage during normal work, RAM is the bottleneck
• Check your current RAM configuration: press Win + R, type msinfo32, and look at Installed Physical Memory and the number of sockets used
• For laptops: look up your specific model to determine if RAM is soldered to the motherboard (non-upgradeable, common on thin ultrabooks after 2021) or uses SO-DIMM slots (upgradeable)
• For desktops: nearly all have 2 or 4 user-accessible DIMM slots and are straightforward to upgrade
• When upgrading from 8 GB to 16 GB: buy a matching kit of two 8 GB sticks rather than a single 16 GB stick — running in dual-channel configuration provides a 5–15% memory bandwidth improvement
• Ensure the new RAM matches your system's DDR generation (DDR4 or DDR5) and that the speed rating does not exceed your motherboard's maximum supported frequency
• After physical installation, enter BIOS/UEFI and enable the XMP (Intel) or EXPO (AMD) profile to run the RAM at its full rated speed rather than the conservative default

If your Windows 11 PC is still slow after applying the software optimizations above and software fixes have not resolved it, a Windows Reset with the "Keep my files" option is the recommended next step before a full clean install. This process removes all installed applications and reverts Windows settings to their defaults while preserving your personal files (documents, photos, videos, desktop items stored in your user profile). The result is essentially a fresh Windows 11 installation with your data intact — eliminating years of accumulated software conflicts, corrupted registry entries, broken service entries, and problematic driver states that no amount of manual optimization can fully address. Most users report this feels like receiving a brand-new computer.

• Before starting: back up all important files to an external drive as a precaution, even though the "Keep my files" option preserves personal data
• Make a list of all applications you will need to reinstall afterward: browsers, Office suite, creative software, utilities, games
• Note any software license keys you may need to re-enter after reinstalling
• Press Win + I and navigate to System > Recovery
• Under Recovery options, click Reset PC
• Select Keep my files to preserve personal documents and photos
• Choose Cloud download (downloads a fresh Windows 11 image from Microsoft — recommended as it ensures the cleanest, most current version) or Local reinstall (uses existing Windows files, faster but may carry over some underlying issues)
• Review the list of apps that will be removed, then click Next > Reset to begin
• The process takes 45–90 minutes and the PC will restart multiple times — this is completely normal

A clean install is the gold standard for resolving a slow Windows 11 system that has resisted every other fix. Unlike a Reset, a clean install wipes the entire drive completely and installs a fresh copy of Windows 11 from Microsoft's servers — eliminating every vestige of the previous installation including the entire Windows registry, all drivers, all system files, and the complete user profile directory structure. The result is the absolute fastest possible state for Windows 11 on your hardware: the same condition Windows was in the moment your PC left the factory, but running the latest 2026 build with all current updates pre-applied.

The process requires a USB drive of at least 8 GB, approximately 30 minutes to prepare the installer on a secondary device, and 45–90 minutes for the actual installation. You will need to back up all personal files before starting, reinstall all applications afterward, and reconfigure your settings from scratch. For users willing to invest this 2–3 hour session, the performance result is unmatched by any other method in this guide. When combined with a simultaneous SSD upgrade (Method 12), a clean install produces the most dramatic performance transformation achievable on existing hardware.

• Back up absolutely everything before proceeding: Documents, Desktop, Downloads, Pictures, Videos, saved games, and any application data in AppData that you need. Use an external drive or cloud storage
• Note your Windows 11 product key if needed — most modern PCs (2018 or newer) have the license tied digitally to the motherboard and it activates automatically after reinstall without entering a key
• On a separate working computer or phone, go to microsoft.com/software-download/windows11 and download the Media Creation Tool
• Insert a USB drive (8 GB or larger) into that computer and run the Media Creation Tool to create a bootable Windows 11 installer — this takes 15–30 minutes depending on your internet speed
• Insert the bootable USB into the PC you want to reinstall, then restart and press the boot menu key (F12, F8, F10, Esc, or Del depending on the manufacturer — look for "Boot Menu" messaging during the initial splash screen)
• Select the USB drive as the boot device
• During setup, when asked which type of installation you want, choose Custom: Install Windows only (advanced)
• Delete the existing partitions on the C: drive using the "Delete" button in the partition screen (your data drive if on a separate physical drive remains completely untouched)
• Select the resulting unallocated space and click Next to install
• Complete the Windows 11 out-of-box experience setup, then download and install your drivers and applications
