About This Update
This update for Windows Activation Technologies helps detect validation errors and activation exploits. This update also detects any tampering attempts made to important Windows 7 system files. Be aware that some counterfeit copies of Windows include malware.
When this update is installed, it performs a validation process for the copy of Windows that is running on your computer. However, this validation process does not affect the functionality of Windows. The update process exits silently if it detects no validation errors, activation exploits, or tampered files.
Tampered Files
If the update discovers a tampered file, it tries to restore the file. This restore may require a restart. If this update cannot restore the tampered files, it will direct you more information on the Internet.Validation Errors or Activation Exploits
Validation errors and activation exploits try to bypass the Windows activation process and are sometimes included with counterfeit copies of Windows. If a validation error or activation exploit is detected, you will be directed to more information on the Internet for resolution of the activation exploit or the validation error. When validation errors or activation exploits are removed, you may be asked to use a valid product key to activate the copy of Windows 7 that is running on your computer. If you decide not to resolve the validation error or the activation exploit at that time, you will be periodically notified that the copy of Windows 7 that is running on your computer is not genuine. Additionally, Windows will provide a link to more information online for resolution.
So , if you are basically running a pirated version of Windows 7 on your machine then beware that as soon as this update is installed in your computer you will be required to get your Windows Genuine, but if you are running a validated copy of Windows 7 then you should install this update.
Rest is in your hands.
