Microsoft is already testing experimental builds of Windows 11 and allowing users to upgrade. But what to do if the new operating system “doesn’t come in” – it is unstable, you don’t like it outwardly, and is incompatible with the software you need? The answer is one – roll back to Windows 10.
There are two rollback options. One is to perform a clean install of Windows 10 from bootable media. Most likely, Windows 11 will not let you install Windows 10 directly from the system using an ISO image, so you have to write this image to a USB flash drive or disk, start from it after manipulating the BIOS and go through the standard clean installation steps. In this case, you will lose all your data, so it is recommended that you save valuable files to the cloud or local storage beforehand.
Microsoft has also provided for a much more painless rollback. You can simply cancel the installation of Windows 11 and return Windows 10 to the state it was in before installing the update. This can be done through “Windows Update” by pressing just a couple of buttons, but there are certain restrictions. First, you only have ten days to revert to a previous version of Windows. If you miss this moment, you will not be able to restore Windows 10 to its original form, since the necessary files will already be deleted. Secondly, you will not be able to rollback if you yourself deleted the files for recovery (they are stored in the Windows.old folder). This could have been done unknowingly, by accident on the machine, or in order to increase the space available in the drive. When a rollback to Windows 10 is not possible with the tools built into the operating system, only a clean install remains.
