Did you upgrade your PC to Windows 10?
If so, ever wonder what happened to the previous version of the OS? It probably disappeared into the mists of Windows past, right?
Wrong. You old OS didn’t get erased; rather, it’s lingering in a system folder called, aptly enough, Windows.old. And depending on the size of that version, it could be hogging a lot of precious space.
What Is the Windows.old Folder?
This folder is created when you upgrade from one version of Windows to another, starting with Windows Vista. The Windows.old folder actually contains all the files and data from your previous Windows installation. It can be used to restore your system to the old version of Windows if you don’t like the new version. If you’re looking for a specific file that wasn’t properly copied to your new Windows installation, you could also dig into the Windows.old folder and find it.
Essentially, the Windows.old folder just contains the old Windows system. From the Windows system files to your installed programs and each user account’s settings and files, it’s all here. The new version of Windows just keeps it around in case you’d like to go back to that older version of Windows or in case you need to dig in and find a file.
Before Deleting Windows.old folder few things to remember:
- You can’t delete windows.old folder like normal folder you delete.
- Make sure you don’t want to get back to your old version of windows.
- Make sure you don’t have any folders or files to recover.
So let’s get started:
STEP 1: Click in Windows’ search field, type Cleanup, then click Disk Cleanup.
You can also right-click the C:\ drive in File Explorer, select Properties, and click the “Disk Clean-up” button under the General tab.
Step 2: Click the “Clean up system files” button.
Step 3: Wait a bit while Windows scans for files, then scroll down the list until you see “Previous Windows installation(s).”
Step 4: Check the box next to the entry, then make sure there are no other boxes checked (unless you do indeed want to delete those items). Click OK to start the cleanup.
And you’re done.
NOTE–The cleanup process can take 10-20 mins, depending upon the size.
