How to Automatically Delete Previous Windows Installation Files in Windows 10 [Windows.old Folder]

Here’s how to delete Windows.old folder automatically in Windows 10. When you upgrade to a newer version of Windows 10 or if you’ve installed Windows 10 on top of the previous installation, Windows will automatically create “Windows.old” folder. This folder contains previous Windows installation files and helps you to downgrade to the previous version if you don’t like or just not comfortable with the newer version.

Typically, the “Windows.old” folder takes up anywhere from five to twenty gigabytes in your C: drive or the system installation drive. If you are not going to downgrade then this is nothing but wasted space. If you are using an SSD for your installation drive then this is especially true as most of the SSDs used for system installation drives are around 60GB and 120GB.

Generally, you can delete Windows.old folder manually or using the Disk Cleanup utility. Alternatively, you can also use the new Storage Sense feature in Windows 10 to automatically delete Windows.old folder. Not to say, Microsoft is releasing two new major updates every year. So, enabling this feature is pretty important to save some disk space and avoid the low disk space warnings.

Automatically Delete Previous Windows Installation Files (Windows.old Folder)

To delete previous Windows installation files or the Windows.old folder, you can use the new Storage Sense feature. When using the Storage Sense feature, it will automatically delete the previous Windows installation files 10 days after you upgrade your system.
