The Windows Update Store folder (commonly known as 'SoftwareDistribution' folder) is the location where Windows stores the downloaded updates.

1. Simultaneously press the Windows + R keys to open run command box.
2. In run command box, type: services.msc and press Enter.

3. Right click on Windows Update service and select Stop.

4. Open Windows Explorer and navigate to C:Windows folder.
5. Select and Delete the “SoftwareDistribution” folder.*
(Click Continue at 'Folder Access Denied' window).

* Note: The next time the Windows Update run, a new empty SoftwareDistribution folder will be created automatically by Windows to store updates.
