my user is using windows7 operating system and it is too slow on his account,its working properly in admin mode so im the admin......some one suggested that i need to reset his profile ....so can anyone just tell me how do i do that without affecting his data,,,,,????
I am basing this answer on you being on a domain using a domain account login?
The easiest way is to re-create the profile. Reboot the machine so that no open handles to the profile are present, login as admin and make a duplicate of the profile folder (most likely under c:\users\%username%) and then in the start menu type 'advanced user' the top search result should be 'configure advanced user profile properties'. Click this and then highlight the profile and delete it. Then get the user to login to the system again, which will recreate the profile. Then copy all his data back into it from the backup.
copying data back to his account is big task since he s a developer....cant i do this without modifying data???
Well the more complex the users requirements the more difficult this is. You can move the data on the same drive, which means you the data transfer would be instant. So you could move the data from the profile to a temp folder on the same drive then move back when you recreate the profile.
When you say the machine is slow, slow doing what? If it works under your admin login is it likely some kind of group policy issue? For example in my company we had an issue with group policy brought over from XP to win7 that was causing the 'auto detect proxy settings' check box in IE to be ticked causing the machine to run really slow while accessing the internet.
