Instructions on how to uninstall Windows 10 20h2 Update: As usual, Microsoft is slowly rolling out the October 2020 (20H2) Windows 10 update to check for errors. If your PC crashes after installing the update, here’s how to roll back to your previous version of Windows 10.
You only have 10 days to uninstall the update.
Windows 10 only gives you ten days to uninstall major updates like the October 2020 update. It does this by keeping around operating system files from earlier versions of Windows 10. When you uninstall the update, Windows 10 will revert to whatever your previous systems were running. This will likely be the May 2020 update.
These old operating system files take up gigabytes of space. So, after ten days, Windows will automatically remove them. This saves disk space but prevents you from going back without reinstalling Windows 10 from scratch.
If Windows is working fine and you can use the normal operating system, you can uninstall the update from Settings
If you don’t see this option here, it’s been more than ten days – or you’ve manually deleted the old Windows installation files. You can’t uninstall the update anymore, so you’ll have to use it (and wait for the fix), reset your PC, or reinstall an old version of Windows 10.
You can also revert to an older version of Windows 10 from the Recovery environment. This is especially useful if your Windows system is not starting up properly – for example, if the system is constantly showing blue or having problems every time it boots.
Windows will automatically display this interface if your PC has trouble booting. You can also open it by holding down the Shift key while clicking the “Restart” option on the Windows 10 login screen or on its Start menu.
When the blue “Choose an option” menu appears, click “Troubleshoot”.
Click “Advanced options” to see additional options.
Click “Uninstall Updates” to remove an update like the October 2020 update.
Select “Uninstall latest feature update” to remove a major update like the October 2020 Update. These are called “feature updates”. The term “quality update” refers to smaller patches, like the monthly updates coming every Tuesday.
If you don’t see this option here, Windows no longer has old operating system files and you can’t uninstall the update.
Follow the instructions on your screen. You will have to choose a Windows user account and provide its password in order to continue.
Hopefully this guide on how to uninstall Windows 10 20h2 update will be helpful to you.
