I installed windows 7 into a new hard disk and created 105 user accounts. From accounts 1 - 100 I can see manage other user accounts (1 - 100 only),but If I log into 101 - 105 and try to manage other accounts I can see its blank. I enabled the built in administrator account even with that account the manage user interface is blank. Could somebody please help me to solve this issue? I create all accounts as administrators.
