I have Vista on Dell Inspiron laptop. When I go to Control Panel and attempt to create a new account by clicking on Add or Remove account, nothing happens. The link does not open. I am the administrator on this computer.
Hi effiya and welcome to the Vista forums
You eventually can create a new user account this way:
Click start, in the search bar type in: netplwiz then press enter, the advance accounts control panel should open (i hope)
Anyway, you maybe should verify the integrity of your system files:

Hope it helps.
