Is there any alternatives for shadow user than should have the ability to be turned as when testing is being done. Rollback rx changes the mbr and does not have any abitity to turn itself off . Virtualizers supporting testing of reboot softwares are needed. Meanwhile i am searching the forum for new ones .I have already tried Disk write copy prof and windows steady state . Problem with shadow user is that all changes made to shadow States is lost on Improper shutdown , i need ways to prevent that.
