I installed Windows 7 after formatting the computer.Then had rollbackrx installed.It was working quite nicely since 10 days.But I am facing lots of problem today. When i started my computer today,the same old way rollbackrx console would come up at first before windows get download.But this time rollback initiated the defrag of snapshot which it does sometimes.Later when window restarted,it started a disk check.I let it happen. Further,I opted to rollback the system to yesterday snapshot since my window would show me the message that you window is not genuine.(I understand that i borrowed the disc from one of my friend since i had to format the PC on an urgent basis,I would be purchasing the license in some day).The PC would restart on rollback the same way it does.But again this time it would start with the same disk check by windows.This time I didnt let it happen and escaped it.The system started very perfectly.When I restarted my computer after certain period of time.I could see that same message of Window not genuine will come up(although i had disabled the option to take any update after the rollback occurerd.I am simply surprised if how could this happen.I started wondering if rollbackrx has automatically rollback to my current snapshot. I again tried to rollback the system,but again the disk check would come up. I would like to understand if there is something within the rollbackrx which is creating some error into my hard disk,by virtue of which windows is checking the disk everytime its restarting. Further,Is there any bug in rollbackrx where sometime it may rollback automatically to its current snapshot despite me rolling back to previous day snapshot. Note: I have windows 7 installed in both the partition i.e C and D.
