As usual, Microsoft is slowly rolling out the October update 2020 Windows 10 (20H2) to look for errors. If your PC experiences a crash after installing the update, here we show you how to revert to your previous version of Windows 10.
You only have 10 days!
Windows 10 it only gives you ten days to uninstall big updates like the October Update 2020. For this, keeps the operating system files from the previous version of Windows 10. When uninstalling the update, Windows 10 it will revert to whatever your previous system was running. This will probably be the May update 2020.
These old operating system files take up gigabytes of space. Then, after ten days, Windows will remove them automatically. This saves disk space, but it prevents me from rolling back without reinstalling Windows 10 right from the start.
