How to Delete Windows.old Folder in Windows 11

This guide will make you aware of five different methods to delete the windows.old folder in Windows 11. As soon as you upgrade your PC to the eleventh iteration of the OS, Windows creates a backup of the previous OS build and stores it inside a folder named Windows.old. Located in the C Drive, this folder contains important system files and configuration settings of your last OS.

Likewise, the app data of previously installed programs and software, as well as the user account’s settings files could also be found there. So if you ever plan on downgrading your PC to the earlier OS version, then this folder could come in handy.

Moreover, if an app isn’t behaving along the expected lines, then you could pick up its settings from that backed-up folder and configure it accordingly on your new OS. But if there’s no intention for you to downgrade to the previous build and all the apps and software are working along the expected lines, then it’s best to delete these windows.old folder right away.

The reason for the same is the astronomical amount of unnecessary storage space that it ends up consuming. Generally, you might find this number to be around 20-30GB, but in some instances (of which I’m a part), this figure could soar up to around 150GB!

So allocating such a huge amount of storage to a backup folder which we have no intention of using shortly doesn’t make much sense. If you also echo this thought, then this guide is here to help you out. In this tutorial, we will show you various methods through which you can delete the windows.old folder in Windows 11.
