Hi, I have flashed BIOS, installed BENQ license on OEM 7 ultimate but I can't find OEM SLP key for BENQ model for Ultimate I have try to install key of another vendor and windows set up 3 day activation. Then I removed product key slmgr.vbs - upk and now I have black screen on desktop and activation window on startup. Is it possible to somehow repair system and try to install another product key? Can anybody help me to find BENQ SLP key for 7 Ultimate???
Of course, I first checked the bios and license by SLIC ToolKit. BIOS SLIC is ok. Perhabs I used banned product key. I don't understand what can I do with windows. Do I need reinstall only?
Some screen shots from SlicTookit would help as for the key only banned key was levono a few years back, any manufacturer ultimate key will activate with correct certificate.
