It would be good if Registry Cleaner could scan for obsolete entries under these two keys, please:
HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags
HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\Shell\MuiCache
I've been examining these using NirSoft's ShellBagsView and MUICacheView, and found entries for dozens of folders (in Bags) and programs (in MuiCache) which no longer exist on my system.
I'm not suggesting that these obsolete entries cause any system malfunction; it's just a matter of housekeeping.
RegSeeker scans both these keys, although it doesn't find all the obsolete entries. CCleaner has a specific option to scan MuiCache, but it never finds anything.
Many thanks.
