Backup/restore your registry using ERUNT, even when running Windows7.

At times even running system restore wont solve your problems, for various reasons.
So Erunt gives you an option to create an automated daily backup of your registry at logon.(and to restore it manually when necessary)
Now ERUNT has been around for many years and always was part of my first aid toolkit up to Windows XP.
However ,as stated by the programmer, Lars Hederer, adding ERUNT to your startup list don't work with Vista and Windows 7 when UAC is enabled.
Nevertheless here's a nice work around to make this nifty program useful in Windows 7(with UAC enabled) :
After installing ERUNT create a new scheduled task to auto-start the program at user logon adding this argument:
C:\Users\XXX\ERDNT\AutoBackup\#Date# /days:14 /noconfirmdelete /noprogresswindow
(14 ,if you only want to store 14 backups deleting older ones)
Important:DON'T choose the default backup location being C:/Windows !!
(that won't work),but you can choose any folder you like in your personal users' folder,or create a new one)
Make sure to tick the box 'run with highest privileges'.
Works like charm! 
(tested on Windows 7)
Enjoy...
