Please does anyone know where i can get a genuine windows application for free, for my computer because it keeps telling me that my system may be at risk and because of this some programs are not running on my computer .
I will be very happy if you my elder brother and Sister can help me out of this.
I love you all.Thanks in advance

Dear Seun T
Coming from an elder sis . the only option you may have is to reinstall you windows even though its that unoriginal one you have. then turn off your automatic updates, cos I guess that message started popping up the moment you tried to update your version of windows (which in this case is not original).
I just saved my system from the same thing. My system is partitioned so, I installed the new windows xp, on my 2nd drive, while i figure out how to remove the former one

Hola

hey the most obvious way out actually is reinstalling your OS but alternatively you can edit your registry using rededit in the command line,follow this procedure
HKEY_CURRENT_USER
SOFTWARE
MICROSOFT
WINDOWS GENUINE ADVANTAGE
Change the key to any genuine key u know and definitely u r good as original.
