5. Select the update you wish to uninstall. The 'Uninstall updates' window will present you with a list of all recently installed updates to both Windows and any programs on your device. Just select the update you wish to uninstall from the list.
You’ll be asked to confirm your choice before Windows does so, so make sure you definitely want to uninstall your chosen update. You may be prompted to restart your device after opting to uninstall a Windows update.
6. (Optional) Note down the updates KB number. Next to the name of the update, you’ll see a Knowledge Base (KB) number in brackets. It can be useful to note this down for any update you wish to uninstall, especially if you end up having to uninstall an update via Advanced startup as outlined below.
