Windows tip of the week

Clean up your Windows leftovers

By Ed Bott

If you're on a mission to recover disk space so you can use it for your own data files, one place to look for potential savings is on the Windows system drive, usually drive C. There, you're likely to find two folders that are prime candidates for a digital cleanup.

The first is Windows.old. As you might guess from the name, this folder contains files and subfolders that were left behind when you installed the most recent feature update. It might also contain your old data files if you performed a manual update and chose the option to keep programs and settings but not data files.

Don't try to delete this folder using File Explorer. Instead, go to Settings > System > Storage and click Temporary Files under your system drive. After the scan completes, select the Previous Windows Installation(s) check box and click Remove Files. You might need to restart to complete the removal.

The second folder to look for is Windows10Upgrade. The presence of this folder means that the Windows 10 Update Assistant was previously installed. To remove the folder and its contents, go to Settings > Apps > Apps & Features and uninstall the Windows 10 Update Assistant. If that option isn't in the list of installed apps, just go to https://go.microsoft.com/fwlink/?LinkID=799445, reinstall the Update Assistant, and then immediately remove it.
