How to Fix System Feels Slow After a Feature Update
Windows just updated and now everything runs slower than before. Here's how to fix post-update slowdowns and get your speed back.
What's Happening
Windows just installed a major update, and now your computer feels sluggish. Programs take longer to open, everything seems to lag, and your once-snappy PC is frustrating to use. This is a common complaint after Windows feature updates, and it's not just your imagination. Updates can change settings, enable new features that consume resources, or sometimes introduce bugs that impact performance. Let's get your computer back to normal speed.
Quick Checks (Do These First)
- Give it time - Right after a major update, Windows runs background tasks for 20-30 minutes. Let your PC sit idle for a while, then restart once more.
- Check Windows Update - Sometimes Microsoft releases follow-up patches to fix update problems within days.
- Make sure the update finished - Go to Settings > Windows Update > Update history to confirm everything installed successfully.
Step-by-Step Fixes
Fix 1: Wait for Background Processes to Complete
This is the most important first step:
- After the update finishes, let your computer sit idle for 30 minutes
- Windows is likely reindexing files, optimizing components, and updating security definitions
- Press
Ctrl + Shift + Escto open Task Manager - Look for processes like "Windows Modules Installer Worker", "Microsoft Compatibility Appraiser", or "Windows Search"
- If these show high CPU or disk usage, they're still working - let them finish
- Restart your computer once more after everything settles
Many "slow after update" problems resolve themselves if you just give Windows time to finish its post-update tasks.
Fix 2: Check and Disable Re-enabled Startup Apps
Windows updates sometimes re-enable startup programs you had previously disabled:
- Press
Ctrl + Shift + Escto open Task Manager - Click the Startup tab
- Look at the Status column - anything marked "Enabled" will start with Windows
- Disable programs you don't need immediately (Adobe updaters, Spotify, Zoom, etc.)
- Click Disable for each unnecessary program
- Restart your computer
Fix 3: Adjust Power Settings
Updates can reset your power plan to "Balanced" which may slow down your system:
- Press
Windows + Ito open Settings - Go to System > Power & battery (or Power in Windows 10)
- Set Power mode to Best performance
- For more control, click Additional power settings
- Select High performance plan (you may need to click "Show additional plans")
- This uses more battery on laptops but improves performance
Fix 4: Update Drivers
Old drivers designed for pre-update Windows can cause slowdowns:
- Press
Windows + Xand select Device Manager - Expand Display adapters
- Right-click your graphics card and select Update driver
- Choose Search automatically for drivers
- Also update Network adapters and any devices with yellow warning icons
- Better yet, visit your computer manufacturer's website and download the latest chipset, graphics, and network drivers directly
- Restart after installing driver updates
Fix 5: Run System File Checker
Updates can sometimes corrupt system files:
- Press
Windows + Xand select Terminal (Admin) - Type
DISM /Online /Cleanup-Image /RestoreHealthand press Enter - Wait for completion (10-15 minutes)
- Then type
sfc /scannowand press Enter - Wait for this to complete (another 10-15 minutes)
- Restart your computer
Fix 6: Check for Known Update Issues
Microsoft's January 2026 updates had several reported problems:
- Search online for "Windows [version] [update KB number] problems" (find the KB number in Settings > Windows Update > Update history)
- Check if others are reporting the same slowdowns
- If it's a widespread issue, you can uninstall the problematic update:
- Go to Settings > Windows Update > Update history
- Click Uninstall updates
- Find the recent update and click Uninstall
- Wait for Microsoft to release a fixed version
Fix 7: Disable New Features You Don't Use
Updates sometimes enable new features that consume resources:
- Press
Windows + Ito open Settings - Go to Privacy & Security
- Review each section and turn off features you don't use
- Pay special attention to Background apps - disable apps you don't need running constantly
- Also check System > Notifications and turn off Show me tips about Windows
Fix 8: Clean Up Temporary Files
Updates can leave behind temporary files that slow things down:
- Press
Windows + Ito open Settings - Go to System > Storage
- Click Temporary files
- Check all boxes including "Previous Windows installation(s)" and "Windows Update Cleanup"
- Click Remove files
- This frees up space and removes update residue
If Nothing Worked
If your system is still slow after trying everything, you have a few options. First, check online tech forums to see if your specific update is causing widespread problems - sometimes Microsoft releases emergency patches within a week or two. Second, you can use System Restore to roll back to before the update if you have a restore point (search for "Create a restore point" in the Start menu, click System Restore, and follow the prompts). Third, as a last resort, you can perform a clean Windows installation, though this requires backing up your data first and reinstalling programs.
When to Call a Pro
Get professional help if: you're not comfortable uninstalling updates or using Command Prompt, the slowdown is severe and affecting your work, you need to roll back the update but don't have a restore point, or you're seeing error messages along with the slowdown. A professional can safely diagnose whether the update exposed an underlying hardware problem or if it's purely software-related. They can also perform a clean Windows installation while preserving your data if that becomes necessary.
