Please add a "Disable Entry" option in Startup Entries, because sometime we want to just "Disable" the Startup Entry and not "Completely" delete it. (for testing purposes - so that we can restore it if something goes wrong!)

Also if possible, please make a short-cut that allow us to "Edit Startup Entry" with right-click context menu in Startup window inside CCleaner. Example: Some startup program always display the "Splash-screen" & Music during the system startup; and I would like to edit the registry to disable it without going through all the hassle finding the registry. And allow us to use Back-up this Registry option (in the context menu) would be a plus!

Just use the included msconfig tool that is in built into Windows for temporary disabling (of course you can still use CCleaner for permanent removal of startups):
Start -> Run -> Type in: msconfig
