Computer slowed down after a Windows update
After a Windows update, your computer runs background tasks like rebuilding the search index and configuring new system files. These use lots of CPU and disk. This is normal and finishes within a few hours.
After a Windows update installs, the computer runs cleanup and setup work in the background that uses CPU and disk resources. This is normal. It finishes within a few hours on most computers. If slowness lasts longer than 24 hours, a driver conflict or bad update is likely.
- ✓Open Task Manager with Ctrl + Shift + Esc and check the CPU and Disk columns
- ✓Leave your computer on and connected to power for at least 2 hours without heavy use
- ✓Restart your computer once if you haven't already after the update

Skip, I just want a technicianCommon mistakes to avoid
- Restarting repeatedly during post-update background work — this interrupts tasks and extends slowness
- Rolling back the update immediately because slowness lasts a few hours — this is normal and expected
- Assuming the computer is broken — checking Task Manager shows whether you're waiting or if there's a real problem
Signs you need professional help
- If slowness persists beyond 24 hours after a clean restart. If Device Manager shows driver warnings that appeared after the update. If you can't identify which process is using high CPU or disk.
