I recently updated my bios (Intel Pentium). Windows started to show that it is not Genuine. When I reinserted the serial key it displayed as follows:

I retyped the product key several times. I also reinstalled my Bios. I also tried the command prompt method of Microsoft

slmgr –upk

slmgr –ipk (your product key)

It did not work either.

Please tell me any other way.

Your BIOS may contain something called SLIC (software licensing description table), updating your BIOS may have reseted that and you lost the Licensing store.
I recommend you re-create it manually, to do that you must:
Make sure you are logged in as Administrator.
Click the Start button and type "cmd.exe" in the search field and open it.

Type(fallowing the order of the numbers):
1) net stop sppsvc
2) cd %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
3) rename tokens.dat
4) cd %windir%\system32
5) net start sppsvc
6) slui.exe

Now you should see Windows Activation dialog appear. Proceed by typing your Windows product key.
