With Windows 10 being plastered all over just about every corner of the Internet that Microsoft can get it, it’s very easy to upgrade to Windows 10 before you are ready or before you know that your hardware and software are actually able to run with Windows 10.
With that, this post will be about the process of uninstalling Windows 10 and returning to your previous version of Windows. One of the first caveats is that as long as you’ve upgraded within the last month, you can uninstall Windows 10 and downgrade your PC back to its original Windows 7 or Windows 8.1 operating system. After the one-month period a complete reinstall of the PC will be required.
If you’ve upgraded a PC to Windows 10, not performed a clean install, but an upgrade, you’ll have an easy option that lets you revert to the last version of Windows. To access this, open the Start menu and select Settings. Click the “Update & security” icon and select “Recovery.” You should see a “Go back to Windows 7” or “Go back to Windows 8.1” option. Click the Get started button to get rid of your Windows 10 install and restore your previous Windows install. Microsoft will ask you why you want to go back. If it’s been over a month, or if you’ve run the Disk cleanup tool and removed the “Previous Windows installations” files, or deleted the C:\Windows.old folder by hand; you’ll no longer see this option. Windows 10 appears to automatically remove the old Windows installation files after a month to free up space.
