I use a messaging program-ICQ---they forced an upgrade on me--and it was working OK until I ran the registry cleaner. After running the cleaner--an option in ICQ(xtraz-game center)stopped working. I reloaded ICQ and the next time I ran the cleaner I put these four registry entries on exclude:
HKCR\Icq.XtraApi
HKCR\MISB.DhtmlPluginWrapper
HKCR\MXtra.DhtmlWrapper
HKCU\Software\Microsoft\Windows\ShellNoRoam\MUICache
My question is--if I upgrade CCleaner will it update these entries into exclude on the new version and is there any safety issue by putting these entries on exclude in the first place?
