Dell OEM Microsoft Windows 7 install suddenly becomes "not genuine" by Windows Genuine Advantage (WGA)
Windows is not Genuine issues that may include error 0xC8000247
User was receiving a popup that told him his version of windows was not authentic.
Why is this happening?
There are numerous items that can cause a "Windows is not Genuine" error in Windows 7. Dell Original Equipment Manufacturer (OEM) Windows uses a special OEM (system Locked Pre-installation (SLP) key and OEM Basic in/out system (BIOS) Flag for activation of the operating system (OS).
In some cases the BIOS flag is set for an older version of Windows and after a period of time WGA will flag the OS as "NOT GENUINE". These include but are not limited to the following:
- Time and date not correct on the system, or time zone selected not matching time zone of actual location.
- All required Windows Updates not installed (Several have to do with changes legislated on Daylight Savings Time).
- Software or driver corruption of the OS
- Viruses and malware
NOTE: This article supplies only ONE possible solution to a specific WGA issue where the BIOS flag has been set, it does not apply to all WGA issues.
What is the solution?
There are several steps that can be used to address this issue. Once time/Date/Time zone and Windows updates have been addressed, if the issue still occurs try the following:
- Download and install the Latest Available BIOS revision for the system then re-run the WGA tool (https://www.microsoft.com/genuine/validate/ , Click Validate Now Button) Issue should be resolved.
- For systems equipped with Intel Rapid Storage Technology, update the IRST drivers from http://support.dell.com or Intel Drivers & Software. Once the driver has been updated, cold reboot (Reboot system from an OFF Power state) the system TWICE .
