If you are one of those lucky (or unlucky) people that installed Windows 10 as a free upgrade you probably have the Windows.old folder that’s taking up lots of space on your C drive. You can remove it by following instructions below or you can wait for Windows 10 to delete the Windows.old folder one month after you performed your upgrade.
In my case the Windows.old folder was almost 32GB as you can see in the video below.
If you are happy that your upgrade went well and not thinking about reverting back to Windows 7 or 8 then it’s safe to remove it and reclaim that space on your drive.
Here is how to remove the Windows.old folder
- Open Disk Cleanup (Search for it if you don’t know where to find it)
- If you are prompted to select a drive, select your C drive and click OK
- In the Disk Cleanup dialog box click Clean up system files
- Select the Previous Windows installation check box, and any other check boxes for the files you want to delete, and then click OK.
You will get a message telling you if you clean up the previous Windows installations or temporary installation files, you will no longer be able to restore the machine back to the previous version of Windows. Are you sure that you want to do this?
Just click on YES and let Disk Cleanup delete it.
Do not delete that folder if you are having any software or hardware related issues, just in case if you need to restore your PC to Win 7/8.
As you can see in my video I have a ghost folder called Windows.old(1). I have no idea why it’s there and why I can’t remove it. As it’s not taking up any space I will just leave it for now.
