How to Speed Up Windows 11: 10 Tips That Actually Work
Why Windows 11 Slows Down Over Time
Windows 11 accumulates startup programs, temporary files, browser extensions, and background services that consume RAM and CPU without the user noticing. The good news: most of these causes have quick fixes without needing to reinstall or buy new hardware.
1. Disable Startup Programs (Biggest Impact)
Open Task Manager (Ctrl + Shift + Esc) → Startup apps tab. Disable everything you don’t need at boot: game launchers (Steam, Epic, Battle.net), Spotify, Discord, OneDrive if not regularly used. Boot time can be cut in half.
Check the Startup impact column: disable High impact items first.
2. Change Power Plan to High Performance
Go to Settings → System → Power & battery and choose Best performance. On desktops, this is never an issue. On laptops, use it only when plugged in.
3. Clean Temporary Files
Settings → System → Storage → Temporary files. Check: temporary files, Delivery Optimization cache, previous Windows installation files, thumbnails. Click Remove files. Freeing 2-10 GB is common.
4. Reduce Visual Effects
Search for Adjust the appearance and performance of Windows in the system search. Select Adjust for best performance. The interface loses some animations but gains real speed, especially on PCs with low RAM or an older CPU.
5. Enable Storage Sense and Other Settings
Storage Sense automatically cleans the recycle bin and temporary files. Go to Settings → System → Storage → Storage Sense.
- Fast startup: Control Panel → Power Options → Choose power button behavior → enable fast startup
- Search indexing: reduce indexed locations if search is slow
- Antivirus: uninstall heavy third-party antivirus and use Windows Defender (excellent in 2026)
- Updated GPU drivers: outdated drivers penalize gaming performance
6-10. Advanced Tweaks
- Virtual memory: let Windows manage it automatically
- Defragmentation: automatic on HDD, never manual on SSD
- Malware: scan with free Malwarebytes — background malware devours CPU
- RAM: if you have 8 GB or less and open many apps, upgrading to 16 GB is the most cost-effective hardware upgrade
- SSD: if you have an HDD, switching to SSD has the biggest possible impact (boot time from minutes to seconds)
How much RAM does Windows 11 need to run smoothly?
8 GB works fine for normal use. 16 GB is comfortable with many tabs, Office, and background apps. For video editing or intensive gaming, 32 GB.
Does reinstalling Windows really speed up a PC?
Yes, a clean install removes all accumulated software. But try the steps in this guide first — in many cases it’s enough and saves you the hassle of reinstalling.
Should I disable Windows Update to gain performance?
No. Windows Update uses CPU during downloads but only temporarily. Disabling it leaves you without security patches. Better to schedule it for nighttime maintenance.
Conclusion
Start with startup programs and the power plan: these are the highest-impact changes and take less than 5 minutes. If the PC is still slow after all these adjustments, consider adding RAM or switching to an SSD.
