Thanks for re-enabling my original account.
After a succesfull Windows Update, it is recommended to delete the Win Update installation files, backup and temp files.which can take up a significant amount of disk space.
Windows Clean Mgr has two operating modes. The normal operating mode does not scan for these Win Update files. However if Win Clean Mgr is executed as Administrator, it scans for and cleans these Win Update files also.
I can imagine that this Win Update cleaning could be incorporated in WAM System Cleaner and performs this cleaning when you 'select all files' or manually tick this check box.
However not a big deal, If not included in WAM I will use Win Clean Mgr for cleaning the files.
