I believe in running periodic preventive maintenance on them. Here is a basic check-list for the maintenance of these computers:
- Review file structure and delete GUID folders. Check OS Drive space.
- Clean up temporary disk files by running cleanmgr.exe (remove System Files as well).
- Delete the temporary files in %SYSTEMROOT%\TEMP and %TEMP%.
- Check System Restore, rstrui.exe.
- Review Programs and Features: appwiz.cpl.
- Review the contents of the Startup Groups:
%AppData%\Microsoft\Windows\Start Menu\Programs\Startup
%ProgramData%\Microsoft\Windows\Start Menu\Programs\Startup - Clear Browser Cache, check browser plugins, toolbars, search-providers.
- Review registry entries in the following registry keys, regedit.exe: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Run - Remove Apple Quicktime if it’s still installed.
- Check for and update unique applications on the computer, if any.
- Check for Office 365 updates.
- Check Antivirus, update if necessary, review quarantine.
- Check for old or unauthorized user accounts.
- Check E-mail store size, if applicable.
- Make a backup copy of any Outlook .pst files, usually here: %homepath%\appdata\local\microsoft\outlook
