ERUNT will only backup your registry, so is of little use if you do not clean the registry.
ERUNT will really help if you clean the registry and recognise a disaster quick enough.
If you do NOT recognise a disaster for a month (until you use a crippled application) :-
Using Windows Restore Point may solve it, with possible side-effects ;
Using CCleaner registry backups may solve it ;
Using ERUNT WILL solve it, with possible side-effects.
SIDE-EFFECTS :-
Both ERUNT and System Restore will undo any registry changes that occurred between causing and recognizing the disaster,
and this may damage any Microsoft Updates and any Applications you installed or updated during this period of time.
The only sure way to recover from any disaster is to use a partition or disc image backup.
I use Macrium Reflect ;
Easeus ToDo is also good ;
Both are available free, and both have extra conveniences when purchased.
Personally I have NEVER used an image backup to recover from any use of CCleaner,
BUT every other month since moving from XP to Windows 7 I have had disasters that made my computer unusable until I restored a backup image.
Each time was due to a Microsoft Security update that I NEVER PERMITTED,
and they crashed through because I had not yet found how to control the updates - it was so much easier with XP.
I am happy to say that after the second disaster I got it nailed.
I fear Microsoft updates far more than I fear "third party" malware ![:rolleyes:]()
