I saw the new “Aro 5” Registry Cleaner advertised today.
The free edition, like many others, offers to scan and fix 20 errors.

It scanned and found 1040 errors.

So what in a Registry is worth fixing, and what is just collected “junk”?

The choices are:
Active X and COM
Application Paths
File Types
Help Files
History Lists
Shared Files
Shortcuts
Software
Sounds
Start Menu
Deep Scan
Current User

Are any of these cleaners actually worth their weight?
Thanks!

I do not hear Windows startup or exit sounds, and have tried nearly everything to get them back. One suggestion I found was this:

Find HKEY_CURRENT_USER and click on it, then delete the entry that says (Default) REG_SZ, it will be replaced with (Default) REG_SZ (value not set) which will restore the startup and exit sounds.
Does anyone know if this will work? Will deleting this registry entry get me into trouble?
Thanks for the help.

it says "there’s no changes to restore", I check all this:

[ ] HKEY_CLASSES_ROOT
[ ] HKEY_CURRENT_USER
[ ] HKEY_LOCAL_MACHINE
[ ] HKEY_USERS
[ ] Start Menu Section
[ ] Obsolete Software
[ ] File Extensions
[ ] Add/Remove Programs
[ ] Shared DLLs
[ ] Fonts Section
[ ] Help File Paths
[ ] Uninstaller Entry
[ ] MRU History Lists
[ ] Empty Registry Keys

There’s something for "not to erase"?

I replace all but stel can’t restore system!

Is there a way to reactivate all the restore points (or marks)?

Thank you very much!!! See you!!!
