Games worked fine yesterday, today they stutter or crash after a Windows update. This happens regularly — Microsoft updates can break GPU drivers, anti-cheat, or change performance-sensitive system behavior.
How to fix it:
- Check which update installed: Settings > Windows Update > Update History. Note the KB number of the most recent update
- Search the KB number + 'gaming' online — if others report the same issue, Microsoft may already have a fix
- Uninstall the update: Settings > Windows Update > Update History > Uninstall Updates > find and uninstall the problematic KB
- Check if VBS (Virtualization Based Security) was enabled by the update: Windows Security > Device Security > Core Isolation. If Memory Integrity is now On, it can reduce gaming FPS by 5-25%. Turn it off for gaming
- Pause updates: Settings > Windows Update > Pause for 1 week (buys time for Microsoft to fix it)
- DDU clean install your GPU driver after the update — sometimes the update corrupts driver state
- If the update was mandatory and can't be uninstalled, check the game's forums for workarounds
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
