How do I know if the ActiveX control used by WGA or OGA is safe to run on my PC?
The first time you request a genuine Windows or genuine Office download from the Download Center or Windows Update, you will be asked to install an ActiveX control. The ActiveX controls used by Windows Genuine Advantage and by Office Genuine Advantage are signed by Microsoft Corp. If you do not see sufficient evidence of the Microsoft signature, you should not download the control.
