hidden standard user account

soz if in wrong place, but i had no idea where to make this topic...

so just found out that theres a hidden account in account manager, that doesnt show in C:/users folder or in LogOn screen, and it wasnt there few weeks ago.

any ideas how it was created? since noone else uses my PC then it was kinda a surprise for me.

EDIT: yeah soz, googled it and found another topic about it in SF and so on... soz but im a NEWBIE in stuff that i dont know how they happen and i like to panic alot since pretty much every week something in my pc stops working...

Where did you get your copy of 7

I will know more when you answer.

But that can be the hidden adminstrator

or

It could have been put there by one of your programs, they sometimes create an account to operate.

its a standard user account, and it was put ther by NET frameworks 1.1 (or something like that) got my copy for free from school (legit, something with microsoft shareing free windows so students wouldnt use other OS and would buy next versions or stuff like that)

edit: thx for fast answer btw
