Windows 7 - Bogus users blocking folder access

Some folders in my computer are blocked as in i cannot modify their content only read them.
When accessing the security tab it shows that my user (which is suppose to be the only one on the computer) has limited access and some users which i consider bogus (they have names like S-347373-26262 etc.) have full access
Tried formatting they are still there
HELP, please

Hi americanu197, Welcome to 7Forums

First and foremost, don't mess with something that you don't understand
Even if you have created only one user in the system, many other users are created by Windows for different tasks and some folders are off limits for normal users.
Deleting the system generated users or playing with those folders can be quite dangerous.

Hope I was not too hard on you. We have seen quite a few users who do things like that and then complain that Windows doesn't work properly.

im not a noobie im a web designer and im talking about folders with all my music music that i personally created on D:

If the folders are created by you, then you can try taking ownership of those folders
Take a look at this tutorial,
Take Ownership Shortcut
Regarding the user account, I think I have seen some accounts that look like that (S-XXXXXX-XXXXX) that were actually system accounts.

unfortunately im at work and i can only try this tonight when i get to my own computer
but why the hell is the system taking over my folders anyway

did you install anything new in the last few days ?

its been going on for quite some time but i formatted last night and the situation remained the same but thats probably because windows left the folder settings there
