To speed up Windows 11, disable startup programs that load when your PC boots, turn off visual effects you do not need, and make sure your storage drive is not nearly full. These three changes alone can cut boot time by 30-50% and make everything from opening folders to launching apps feel noticeably faster, even on older hardware.
Windows 11 runs well on modern hardware but slows down over time as apps pile up, background processes multiply, and temporary files consume storage. Microsoft’s own system requirements (4GB RAM, 64GB storage, 1 GHz dual-core processor) represent the bare minimum, and machines near those specs struggle with default settings enabled. The good news is that most slowdowns are software-related and reversible without upgrading any hardware.
This guide covers 15 proven fixes ordered by impact, starting with the changes that deliver the biggest speed improvement and ending with advanced tweaks for users who want maximum performance.
Why Windows 11 Gets Slow Over Time
Every application you install can add startup entries, background services, and scheduled tasks that consume CPU, RAM, and disk I/O even when you are not using the app. A fresh Windows 11 installation boots in 10-15 seconds on an SSD. If you are choosing a new machine, our best laptop for programming guide covers systems that run Windows 11 at peak performance out of the box. After a year of regular use with 30-50 installed applications, that same machine may take 30-60 seconds because dozens of programs now load at startup.
Windows 11 also enables visual effects by default: transparency effects, animations, smooth scrolling, and window shadows. These look polished but consume GPU and CPU resources continuously. On systems with integrated graphics or older dedicated GPUs, disabling these effects frees resources for the applications you actually use.
Temporary files, Windows Update caches, browser caches, and recycled items accumulate silently. A system drive with less than 15-20% free space slows down because Windows needs free space for virtual memory (page file), temporary files during updates, and file system operations. Running low on storage is one of the most common and most fixable causes of a slow PC.
15 Ways to Speed Up Windows 11
1. Disable Startup Programs
Press Ctrl + Shift + Esc to open Task Manager, then click the Startup apps tab. This shows every program that launches when Windows boots. Right-click any app you do not need immediately at startup and select Disable. Common offenders include Spotify, Discord, Steam, Microsoft Teams, Adobe Creative Cloud, OneDrive, and manufacturer utilities like Lenovo Vantage or HP Support Assistant.
Keep enabled: your antivirus software, audio drivers (Realtek), and any cloud sync service you rely on (OneDrive or Dropbox if you use them actively). Disable everything else. You can still launch these apps manually when you need them. Reducing startup programs from 15 to 5 typically cuts boot time by 20-40 seconds on HDD systems and 5-15 seconds on SSD systems.
2. Turn Off Visual Effects
Open Settings > System > About > Advanced system settings (or search “performance” in the Start menu and select “Adjust the appearance and performance of Windows”). In the Performance Options dialog, select Adjust for best performance to disable all visual effects, or select Custom and keep only “Show thumbnails instead of icons” and “Smooth edges of screen fonts” enabled. Click Apply.
Separately, disable transparency effects: Settings > Personalization > Colors > Transparency effects > Off. Disable animations: Settings > Accessibility > Visual effects > Animation effects > Off. These changes make the interface feel snappier, especially on systems with 4-8GB RAM or integrated graphics.
3. Free Up Disk Space with Storage Sense
Open Settings > System > Storage and enable Storage Sense. Click “Storage Sense” to configure it: set it to run every week, delete temporary files older than 14 days, and empty the Recycle Bin after 30 days. Click Run Storage Sense now for an immediate cleanup.
For a deeper cleanup, scroll down and click Cleanup recommendations. Windows shows temporary files, large or unused files, and unused apps that you can remove. The “Temporary files” section often recovers 2-10GB by clearing Windows Update cache, delivery optimization files, and previous Windows installations. After a major Windows update, the previous installation backup can consume 10-20GB until you delete it here.
4. Uninstall Apps You Do Not Use
Open Settings > Apps > Installed apps and sort by size or date installed. Uninstall applications you no longer use, especially large programs like unused games, trial software, manufacturer bloatware, and old versions of software you have upgraded. Each uninstalled app removes its background services, scheduled tasks, and storage footprint.
Windows 11 comes with pre-installed apps you may not need: Clipchamp, Microsoft News, Solitaire Collection, and Xbox Game Bar (if you do not game). Right-click these in the Start menu and select Uninstall. For stubborn pre-installed apps that lack an uninstall option, open PowerShell as administrator and use Get-AppxPackage *appname* | Remove-AppxPackage to remove them.
5. Upgrade to an SSD (If You Still Use an HDD)
If your PC still runs Windows from a traditional hard drive (HDD), upgrading to a solid-state drive (SSD) is the single most impactful hardware change you can make. An SSD reads data 10-50x faster than an HDD. Boot time drops from 60-120 seconds to 10-20 seconds. Applications launch in 1-3 seconds instead of 5-15 seconds. File Explorer opens instantly instead of hanging for 2-5 seconds.
A 500GB SATA SSD costs $30-50 in 2026 and fits in any laptop or desktop that currently has a 2.5-inch HDD. An NVMe SSD (M.2 form factor) costs $40-60 for 500GB and is 3-5x faster than SATA but requires an M.2 slot on your motherboard. Use free tools like Macrium Reflect Free or Samsung Data Migration to clone your existing drive to the new SSD without reinstalling Windows.
6. Add More RAM
Windows 11 requires 4GB RAM minimum but runs poorly at that level. With 4GB, opening a browser with 5-10 tabs alongside any other application causes heavy swapping to the page file, which slows everything dramatically. 8GB is the practical minimum for comfortable daily use. 16GB handles multitasking with browsers, Office, and light creative work without slowdowns.
Check your current RAM: open Task Manager (Ctrl + Shift + Esc) > Performance > Memory. If usage regularly exceeds 80% during normal tasks, adding RAM will improve performance. Desktop RAM (DDR4 or DDR5) costs $15-25 per 8GB stick. Laptop RAM upgrades depend on whether your laptop has accessible RAM slots (many ultrabooks have soldered, non-upgradeable RAM).
7. Disable Background Apps
Open Settings > Apps > Installed apps, click the three dots next to an app, select Advanced options, and under “Background app permissions” select Never. Do this for apps that do not need to run in the background: news apps, social media, weather widgets, and entertainment apps. Keep background permissions for messaging apps, email, and VPN software.
Windows 11 removed the centralized background apps toggle that existed in Windows 10. You now need to configure each app individually, which is tedious but gives you granular control. Focus on the top 10 apps by battery or resource usage shown in Task Manager.
8. Update Windows and Drivers
Open Settings > Windows Update and install all pending updates. Microsoft regularly releases performance optimizations, bug fixes, and driver updates through Windows Update. An outdated graphics driver can cause stuttering, and outdated chipset drivers can cause USB and power management issues that affect overall responsiveness.
For GPU drivers specifically, download the latest version directly from NVIDIA (GeForce Experience or nvidia.com), AMD (amd.com/drivers), or Intel (intel.com/download) rather than relying on Windows Update, which often ships older driver versions. Updated GPU drivers improve not just gaming but also desktop compositing, video playback, and browser rendering.
9. Adjust Power Plan to High Performance
Search “power plan” in the Start menu and open Choose a power plan. Select High performance (you may need to click “Show additional plans” to see it). The default Balanced plan throttles CPU speed when demand is low to save energy, which introduces micro-delays when switching between tasks. High performance keeps the CPU at higher clock speeds, making the system feel more responsive.
On laptops, use High performance when plugged in and switch to Balanced on battery to preserve battery life. You can automate this by right-clicking the battery icon and configuring different plans for plugged in versus battery.
10. Disable Search Indexing on Large Drives
Windows Search indexes file names, contents, and metadata to make search results appear instantly. On HDDs, this indexing process runs continuously in the background and competes with your active applications for disk I/O. Open Services (search “services” in Start menu), find Windows Search, double-click it, set Startup type to Disabled, and click Stop.
On SSD systems, indexing has minimal performance impact because SSDs handle random reads efficiently. If you use Windows Search frequently, keep indexing enabled on SSDs. If you rarely search for files by content and your system feels slow during file operations, disabling it frees disk and CPU resources.
11. Scan for Malware
Malware, adware, and potentially unwanted programs (PUPs) consume CPU and network resources in the background. Open Windows Security > Virus & threat protection > Scan options and run a Full scan. This takes 30-90 minutes depending on drive size and checks every file on your system.
For a second opinion, download and run Malwarebytes Free (malwarebytes.com). It catches adware and PUPs that Windows Defender sometimes misses. Browser extensions that inject ads or redirect searches are another common source of slowness. Check your browser extensions (Chrome: chrome://extensions, Edge: edge://extensions) and remove anything you do not recognize or no longer use.
12. Defragment HDD or Optimize SSD
Search “defragment” in the Start menu and open Defragment and Optimize Drives. Windows normally runs optimization automatically on a weekly schedule. If your HDD shows fragmentation above 5%, click Optimize to defragment it. Defragmentation rearranges scattered file fragments so the read head moves less, improving sequential read and write performance by 10-30%.
For SSDs, Windows runs TRIM commands instead of defragmentation. TRIM tells the SSD which blocks are no longer in use, allowing the controller to manage wear leveling and maintain write speeds. Do not defragment an SSD. It does not help performance and causes unnecessary write wear that shortens the drive’s lifespan. The Optimize Drives tool handles this correctly by default.
13. Increase Virtual Memory (Page File)
If your RAM is limited and you cannot upgrade, increasing the page file size gives Windows more virtual memory to work with. Open Settings > System > About > Advanced system settings > Performance Settings > Advanced > Virtual memory > Change. Uncheck “Automatically manage paging file size for all drives.” Select your system drive, choose Custom size, and set Initial size to 1.5x your RAM and Maximum size to 3x your RAM (for example, 12,000 MB initial and 24,000 MB maximum for 8GB RAM). Click Set, then OK.
This does not replace real RAM but prevents hard crashes and severe slowdowns when memory is exhausted. Place the page file on the fastest drive in your system (preferably an SSD) for best results.
14. Disable Cortana and Widgets
Cortana and the Widgets panel consume memory and occasionally CPU even when you are not interacting with them. To disable Cortana: open Task Manager > Startup apps > right-click Cortana > Disable. To disable Widgets: right-click the Taskbar > Taskbar settings > toggle Widgets off. To disable the Widgets process completely, open Group Policy Editor (gpedit.msc, available on Pro and Enterprise editions) and navigate to Computer Configuration > Administrative Templates > Windows Components > Widgets > Allow Widgets > Disabled.
On Windows 11 Home, you can disable Widgets through a registry edit: open Registry Editor, navigate to HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftDsh, create a DWORD value named AllowNewsAndInterests and set it to 0. Restart your PC for the change to take effect.
15. Reset Windows as a Last Resort
If your system remains slow after trying all fixes above, a clean reset removes accumulated software problems. Open Settings > System > Recovery > Reset this PC. Choose Keep my files to preserve documents, photos, and personal files while reinstalling Windows and removing all installed applications. Choose Remove everything for a completely fresh start.
Before resetting, back up any files not stored in cloud services. Note your installed applications so you can reinstall them afterward. A reset followed by selective reinstallation of only the apps you actually use results in a system that performs like new. Many IT professionals recommend a clean reset every 2-3 years to maintain peak performance.

How to Check What Is Slowing Down Your PC
Open Task Manager (Ctrl + Shift + Esc) and click the Processes tab. Sort by CPU to find processes consuming the most processor time. Sort by Memory to find RAM-heavy applications. Sort by Disk to identify programs causing heavy read/write activity. Any process consistently using more than 20% of a resource when you are not actively using it is a problem worth investigating.
Common resource hogs include: Windows Defender running a background scan (MsMpEng.exe, 20-40% CPU temporarily), Windows Update downloading in the background (svchost.exe), OneDrive syncing large files, browser tabs with active video or complex JavaScript, and antivirus software performing scheduled scans. Most of these are temporary and resolve within minutes. Persistent high resource usage from a single process indicates a problem that needs attention.
The Performance tab in Task Manager shows real-time graphs for CPU, Memory, Disk, and GPU utilization. If your disk graph stays at 100% constantly, your storage drive is the bottleneck (common with HDDs). If memory stays above 90%, you need more RAM or fewer concurrent applications. If CPU stays above 80% during light tasks, a specific process is consuming excessive resources.
Frequently Asked Questions
Does Windows 11 run slower than Windows 10?
On identical hardware, Windows 11 uses approximately 200-400MB more RAM than Windows 10 due to additional features like Widgets, Teams integration, and enhanced security (VBS and HVCI). On systems with 8GB or more RAM, the difference is negligible. On 4GB systems, Windows 10 runs noticeably better. If your hardware meets Windows 11 requirements comfortably, performance is comparable after disabling unnecessary features.
How often should I restart my Windows 11 PC?
Restart at least once per week. Restarting clears temporary memory leaks, completes pending Windows updates, resets background processes that may have accumulated errors, and frees RAM consumed by closed applications that did not release memory properly. If your PC feels sluggish and you have not restarted in several days, a restart alone may resolve the issue.
Will disabling Windows Defender speed up my PC?
Disabling Windows Defender eliminates the 2-5% CPU overhead from real-time scanning but leaves your PC completely unprotected against malware. This is not recommended. If Defender causes noticeable slowdowns, add exclusions for folders you access frequently (like development project directories or large media libraries) in Windows Security > Virus & threat protection > Manage settings > Exclusions. This reduces scanning overhead without removing protection.
Is 8GB RAM enough for Windows 11 in 2026?
8GB RAM is adequate for basic tasks: web browsing with 10-15 tabs, Microsoft Office, email, and video streaming. It becomes insufficient when running multiple productivity apps simultaneously, editing photos or video, or using memory-heavy applications like Visual Studio, Docker, or virtual machines. For comfortable multitasking in 2026, 16GB is the recommended minimum. RAM prices have dropped enough that 16GB should be standard for any new PC purchase.
Does game mode in Windows 11 improve performance?
Game Mode (Settings > Gaming > Game Mode) prevents Windows Update from performing driver installations and blocks notification pop-ups during games. The actual FPS improvement is typically 1-3% at most, which is within margin of error for most benchmarks. Game Mode does not hurt performance, so keeping it enabled is fine, but do not expect dramatic improvements. For gaming peripherals, our guide on connecting a PS5 controller to PC covers the full setup. Disabling startup programs and updating GPU drivers have a much larger impact on gaming performance.
