Windows takes up a lot of space on your C drive. After pushing more bloatware updates and some big software, your C drive can run out of space very quickly. You may have noticed a folder named “Windows.old” in your system drive. If you check its size, it can easily eat up 8GB or more of your storage.
It is not possible to simply delete a folder and you need to take ownership of the folder to do so. But you can delete a folder using several methods which we will discuss in the article below.
What is the Windows.old folder and should you delete it?
Whenever you upgrade to a new version of Windows (via Windows Update) or perform an in-place Windows upgrade, the operating system creates a Windows.old folder. It contains all your old system and personal files, and you can use it to revert to an older version of Windows if you want. But this folder takes up a lot of space on your C drive, which can be inconvenient for users who have just upgraded their PC.
Windows will automatically delete Windows.old 30 days after it was created. But if you need that storage space right now, you can try any of these methods to remove the folder from your PC.
