Bgmi Tips & Tricks: Pro Player Guide (2026)
Windows 11 slow after update is one of the most common complaints users face after installing a major or cumulative update. Your PC was running fine yesterday, and today it feels sluggish, laggy, or unresponsive. Apps take longer to open, startup time increases, and sometimes even basic tasks feel heavy.
The good news? This usually isn’t a hardware problem.
Most Windows 11 performance issues after updates happen because background services are re-indexing files, drivers need optimization, or startup programs increase automatically. In this guide, I’ll show you how to fix Windows 11 slow after update in 10 minutes using safe, built-in settings — no risky tools, no complicated tweaks.
Let’s speed up your PC the right way.
After an update, Windows may continue background configuration.
👉 Click Start → Power → Restart
A proper restart clears temporary cache and completes update installation. This simple step fixes lag for many users.
Too many startup apps cause Windows 11 lag after update.
Press Ctrl + Shift + Esc
Open Task Manager
Go to Startup
Disable unnecessary apps (Discord, Adobe, Teams, etc.)
This reduces boot time and improves overall performance instantly.
If your PC feels slow, check disk usage.
Open Task Manager
Click Performance → Disk
If it’s near 100%, try this:
Press Win + R
Type services.msc
Find SysMain
Right-click → Stop
This helps if Windows 11 is causing high disk usage after update.
Sometimes slow performance is due to outdated drivers.
Go to:
Settings → Windows Update → Advanced Options → Optional Updates
Install any available driver updates.

Keeping drivers updated reduces Windows 11 lag and system freezing.
Background apps consume RAM and CPU.
Go to:
Settings → Apps → Installed Apps
Click three dots → Advanced options → Set Background permissions to Never (for unnecessary apps).
This lowers RAM usage and fixes Windows 11 performance problems.
If your PC is low-end, animations can slow it down.
Search View Advanced System Settings
Click Performance Settings
Choose Adjust for Best Performance
This disables heavy animations and improves responsiveness.
Temporary files build up after updates.
Go to:
Settings → System → Storage → Temporary Files
Remove update cache and junk files safely.
✔ Restart PC
✔ Disable startup apps
✔ Stop SysMain if disk usage high
✔ Install optional driver updates
✔ Disable unnecessary background apps
✔ Adjust visual effects
✔ Clear temporary files
Follow these steps and your Windows 11 slow after update issue should be resolved within 10 minutes.

Because background services re-index files, drivers reset, and startup apps increase automatically after updates.
Usually 1–2 hours while background tasks complete. If longer, apply the fixes above.
No. Most slowdowns are temporary and fixable with optimization.
Not recommended unless it causes major system errors. Try performance fixes first.
Windows 11 slow after update can feel frustrating, but it’s rarely permanent. Most performance issues happen due to background processes, startup overload, or driver conflicts — not hardware failure.
With the simple tweaks above, you can restore speed and improve responsiveness safely without using third-party software.
