Hi All, my computer had issues going into BIOS since i mistakenly changed it to Legacy from UEFI. I had to take it to repair shop and they overwrote the BIOS on a chip on motherboard. Now Windows is asking for activation. How can i reactivate it? I remember extracting the key long back but cannot find it. Please help out. Edit: It is ACER V5-571G laptop.
Update: i was able to extract key again using the PID tool here on forum. Putting that key works but with every restart it asks for activate Windows.
run in cmd slmgr.vbs -rearm reboot then retry the key edit: might have to check the system dism /Online /Cleanup-Image /RestoreHealth sfc /scannow
Is it still under warranty? I'd take it back & get Acer to inject a new key. MS gives the oem's an allocation of free keys for dead/replacement boards, etc. You would need special tools to inject your key yourself & I don't think they are available/leaked... Perhaps they could re-inject your key...
I suspect you should be able to inject it using WinFlash32/WinFlash64 from the Acer BIOS 1.22 update: Code: WinFlash64.exe /patch /slp OA3.BIN /exit Google around for a OA3.BIN file and then, using a hex editor, replace the key inside with yours. Flash and you should be done.
