What Is the Windows.old Folder?

The function of the Windows.old folder is to make it easier for you to roll back a major Windows update. The folder keeps a copy of the previous version of your OS, in case you need to go back to it for whatever reason.

Another scenario in which Windows will create the Windows.old folder, is when you perform a fresh installation of the same version of Windows, i.e. reset your PC.

Usually, the folder will be several gigabytes in size. This is because it contains all your installed programs and program data. This is quite useful because you can effectively restore programs from Windows.old.

It’s important to note that the folder will not remain on your hard drive, indefinitely. Windows automatically deletes it within a span of 10 or 28 days, depending on how you configured Windows update.

Typically, you can find the folder at: C:\Windows.old. But, if you have System Restore turned off, Windows may not create the folder at all.

How to Delete the Windows.old Folder

Another feature of the folder is that it cannot be deleted in the traditional way. Attempting to do so will result in Windows returning an error. If a user wants to delete the folder to free up disk space, they can:

  1. Right-click on Local Disk (C:), and go to Properties > General > Disk Cleanup. Ensure that the Windows Update Clean-up option is checked. Click on OK.
  2. You can also go to Settings > System > Storage > Configure Storage Sense or run it now. Click on Clean now to remove temporary files from your computer, including the Windows.old folder.

Data Recovery Tips

There are a few tips that will substantially increase your chances of a full data recovery:

  • Try not to write or create new data to the hard drive that was affected by data loss. Doing so can overwrite the previous data on your storage device, making data recovery more difficult than it has to be.
  • Use the most functional data recovery method, first. After each attempt at data recovery, the chances of actually restoring your files become less.
  • If the storage device is physically damaged or the data loss occurred in a TRIM enabled SSD, it’s best to contact a data recovery service, instead of going the DIY route.


The Windows.old folder is quite important, and you shouldn’t try to delete it right away. Some updates can be buggy and thus, it’s always convenient to know you can revert to an older version later. While it’s possible to restore your lost data, regularly backing up your files is essential to prevent data loss as well.
