== How to Fix a Slower Windows 10 After an Update ==
''Note: all the commands below take a while to run so go fix a tea or coffee while they are running. Good luck.''
=== 1. Roll Back the Most Recent Windows Update ===
To uninstall your most recent update:
***Settings >*** ***Update & Security*** > ***Windows Update*** > ***View update history***.
Next, click on ***Uninstall updates***. Look at the list of installed updates. Uninstall the update you just did. If that doesn't help try next one.
=== 2. Repair Corrupt or Damaged Files ===
System-critical Windows files might be corrupted or damaged and cause slowdown issues in Windows 10.
Try the System File Checker tool following the steps below:
# Go to the ***Start menu*** search bar, type in 'command prompt'.
# Run the Command prompt as an administrator by right-clicking the search entry and clicking ***Run as administrator***.
# You will see a black screen with white text. In the Command prompt, type ***sfc /scannow*** and hit ***Enter***.
After the scan is complete, reboot your system. If a recent update did cause any corruption, this should fix it.
If that didn't work try:
# Go to the ***Start menu*** search bar, type in 'command prompt'.
# Run the Command prompt as an administrator by right-clicking the search entry and clicking ***Run as administrator***.
# In the Command Prompt type ***DISM /Online /Cleanup-Image /CheckHealth*** and hit ***Enter***.
# If there are no corruption issues, you can run a more advanced scan using ***Dism /Online /Cleanup-Image /ScanHealth***
# If you find corruption issues through the above step, run the ***Dism /Online /Cleanup-Image /RestoreHealth*** command to download and replace the damaged files. Restart your computer after the command gets executed, then run the ***SFC command*** again to repair any errors.
=== 3. Disable Background Apps ===
Unnecessary background apps can cause Windows 10 to slow down after an update. Try disabling them to see if that fixes the problem.
# Open the Windows ***Settings***.
# Then, click on ***Privacy > Background Apps***.
# Choose which apps can run in the background section by turning off all the unimportant apps.
