That won't work if the administrator profile is password protected as you'll be requested to enter a valid administrator password.

Under Windows XP, it's not a problem as by default you always are working with administrator privileges.
Under Windows Vista and 7, the default is a restricted level and you need to escalate to administrative privileges to change system whide things, like installing drivers.

You may be able to bring it to a computer shop and have them do a password reset. It won't be free and you'll need to give some proof that it's realy your computer.

For your inhability to access several sites, take a look at the file:
C:\Windows\system32\drivers\etc\hosts (extention-less text file)
If a blocked site appears in a line starting with 127.0.0.1, suppress that line. Save the file, the effect is immediate, you don't need to restart the computer.
Do you connect via a router?
Check it's configuration, it may be set to only allow access to a few sites (using a small white list), or to prevent access to several sites (using a to broad black list).
Check the settings of any firewall present.

Hi came across you wilst looking for something, if your trying to add a printer, when you have the installer on your desktop ready to install put your mouse curser over the said program and right click once to open drop down menu you should see a run as admin box there, then one left click should allow you to run your program and install it.

hope this helps
