Terrible! Somebody stole my system prop.
 

I tried everything I can imagine but no result. Suddenly I discovered that when I should click on Windows update I came to a website telling me in two sentences that I could update my mac there. Somebody have been inside here and mixed up almost everything. I managed to fix several things but the problem with windows update and that system restore is gone I don't know how to fix, Is it possible at all??? I went down and looked in my registry too but with no result. Please, if someone out there know something about this problem contact me!

What happens when you push the Windows key + the Pause/Break key together?
System properties window should open.

I can't really understand what you mean... Maybe you didn't understand what I tried to explane, it's not always so easy to say it in the right way. When I push WINDOWS UPDATE I am taken to a website like this:

Thank you for your interest in obtaining updates from our site.

Someone have had some fun here you see...
System tools are not there at all anymore.

What Operating System do you have?
What Internet browser are you using?
What's the website address that is giving you the error?

Hi,
Which operating system are you using? Is it XP or Vista?
Did you recently download any file from internet?
Did you try to access system properties in safe mode by logging as the administrator?
We can fix it, so don't worry.

Re:
 

I cannot logon as system administrator. It is just not possible!

I get the same message when I click your link.

See what happens when you click this link then Security and Updates from the menu on the right.

You should not need to, but could help determine if you are experiencing a user problem versus a system wide issue.
