In the last few days, contrary to my recommendation, millions of people have upgraded Windows 7 systems to Windows 10 (along with Windows 8.1 systems which I acknowledged the desideratum of an upgrade to Windows 10). But suppose you have tried Windows 10 and now you want your old system back? As long as it has not been more than 30 days since you installed Windows 10, there is an easy way to downgrade.
Here is the procedure. Since something can always go wrong, first back up any personal files and data. Also, if a laptop or tablet is involved it will need to be plugged in since the rollback can take a while.
- Open the Start Menu
- Click or tap “Settings”
- Click or tap “Update & security”
- In the dialog window that opens, choose “Recovery” in the left column
- The image below shows the options that are then displayed. Under the entry “Go back to Windows x” (where x is 7 or 8.1), click or tap “Get started”.
- A blue window (example shown below) will open asking why you want to roll back the system. Choose an answer and click “Next”.
- Another blue window with some information will open. Click “Next”.
- The rollback will start. Depending on your system, the process may take several hours.
The files needed for reverting to a previous system are in a folder Windows.old. If you have deleted these with a clean-up procedure, then no rollback is possible. Once you are sure that you are happy with Windows 10, the Disk Cleanup procedure can be used to remove these files.
