After some trial & errors, I finally decided to do windows activation over the phone through Microsoft's automated process. Here are the steps I did to activate my Windows license through phone -
- Opened RegEdit.exe on the Windows machine.
- Browsed to HKEY_LOCAL_MACHINE/ Software/ Microsoft/ Windows/ CurrentVersion/ Setup/OOBE/
- Changed MediaBootInstall from 1 to 0.
- Opened a Command Prompt as an administrator (Right click & Run as Admin).
- Typed & Executed - slmgr /rearm to reset activation key.
- A message informed that activation key has been reset.
- Restarted Windows.
- After the reboot, again opened a command prompt as an administrator.
- Typed & Executed - slui.exe 4
- Now Windows Activation screen asked to select the user country and provided phone numbers & long verification numbers to activate by phone.
- Called the phone number on the screen and followed the instructions.
NOTE - Even though it is a phone activation, it is fully automated and I did not speak to any human.
