after reading the tweakhound' super xp tweaking guide on services i disabled couple of them. And no i dont remember which ones.
So now when i open my windows task manager and click on the processes tab, the user name column is blank.
Here is a picture of a normal task manager
Under the user Name everything is blank.
I hope i explained it well.
I am using windows xp sp1.
I hope that somebody can help me.
