deleting old windows files but disk space is still full

Here's the proper way to delete the Windows.old folder:

Step 1: Click in Windows' search field, type Cleanup, then click Disk Cleanup.

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.
