Hi,
This can be fixed by doing following
Windows key + R
Type Regedit
Navigate through each folder below
-HKEY_USERS
-.DEFAULT
-Software
-Microsoft
-Windows
-CurrentVersion
-Bluetooth
-ExceptionDB
-Addrs
Delete the folder within Addrs
Once deleted wireless keyboard pin should be displayed by windows and allow connection
Good luck
