Your operating system has done an automatic Windows update and the new update improves on the anti-piracy credentials that inspect systems for counterfeiting. It has read your system as having a pirated version of its software....what likely has happened is you have a copy of windows that had a Volumn License that has now been blocked. You either have to buy a copy of the windows you are using in order to get a proper product key, or and this is just for information.....there are small programs that will bypass this windows validation stuff and reactivate the system. That will have to be "Googled" because it is illegal and won't be discussed in an open forum.

If you have a black screen it means the system cannot boot into your master boot record, you should reinstall the system using a bootable Windows XP CD, and perform a repair,( not the Repair Console).

When youre in the Windows XP Wizard screen, press enter , accept the license agreement, and then it will check for existing windows xp partitions, press R to repair the existing Windows XP installation, and wait til it gets your system restored.

It is what it says - your copy of Windows is pirated and has been deactivated. You need to go back to whomever you bought it from and ask for your money back, or a legal copy.

sir it is possible that you got a pirated or counterfeited copy, you should reformat your drive and buy a licensed windows program. and use that to install your programs to you computer. thank you and fix ya.
