What message is shown when you try to access "Help and Support"?
If the message shown is : "Windows cannot start Helo and Support because a service named "Help and Support" is not running"
then you need to enable/start this service. To do so :
Open Start Menu -> Run
and type services.msc
and pres Enter
In the Window opened, look for a service named Help and Support
, right-click on it and select Start
BTW Registry Cleaners are not advised on BleepingComputer. Read this post : http://www.bleepingcomputer.com/forums/ind...p;#entry1004272
However, most registry cleaner softwares make registry backups before they make changes to Windows registry. So you can look for undoing the changes made by your registry cleaner software, if possible.
