Faced with Low Disk Space Trouble after Installing Windows 10 Anniversary Update

Some users who installed Windows system on a solid state drive (Usually 128GB) are reporting that after installing Windows 10 anniversary update, they're faced with low disk space trouble. And their PCs are running extremely slow due to the insufficient disk space. They checked the storage properties, finding that temporary Windows installation files, previous Windows installations and a Windows.old folder took a total amount of disk space up to 50GB. Now they wonder how to delete temporary files including Windows.old in a safe way and free up some significant space on the SSD.

STEP 1. Backup Windows.old Folder

Users should understand the existence of Windows.old folder included in Windows temporary files and what these files for. To be specific, when you upgrade your Windows 10 to anniversary update version 1607, Windows 10 automatically creates a backup of your previous build of Windows 10 to a folder called Windows.old so that users can uninstall Windows 10 anniversary update and go back to the previous build if required. Now to free up the space taken by Windows.old, at the same time, do not cut the opportunity of going back to the old versions, try to backup Windows.old file folder and revert back to old system at any time by using EaseUS file backup software.
