Windows 10 is regularly serviced with quality and security updates which apply on top of the large feature updates. While these generally go smoothly, some updates can cause more issues than they solve – such as when KB4512941 massively increased CPU consumption on some devices.
Windows lets you see which updates are installed on your PC, so you can identify if your device has received a problematic one. Begin by opening the Settings app and clicking to the "Update & Security" category.
On the Windows Update page which appears, click the "View update history" button. A new screen will display with a list of all the quality and security updates that have been applied to your PC.
The page is divided into sections for feature updates, quality updates and security updates. You can click any update's title to get online information about what it includes.
If you want to remove an installed update, click the "Uninstall updates" link at the top of the page. Not all updates can be removed. The "Installed Updates" page will open in Control Panel so you can select and remove any troublesome packages.
