hey dude thanks for that help. I don't have the original dvd of win7 it's a oem copy. I just wanted to know that the lenovo logo in system info why dosen't appears itself is it because my windows is not original or what? is it harmful for the laptop if i am operating without the logo?
Moreover I just closed all the the things in background and started windows working experience index so i got back my old 4.5 index
And i had to reinstall win7 because in the dvd their was a crack to activate i started that and when my laptop restarted it gave a black screen restarted and same went on for 2 to 3 times and then i had to reinstall to get my laptop back in working situation.
Thanks in advance for the reply
