Welcome to the CCleaner Forums davidmac!

Note: CCleaner permanently removes the startup program if you select delete, once you delete it there's no undo option, and if the program is needed to re-enable it at startup you must manually input it in the registry!
You can look up the files that load during startup at
processlibrary.com. If you're unsure about permanently removing a startup program you should instead use msconfig via this:
Start > Run > Type in: msconfig
With msconfig you can re-enable any disabled startup program.
