Hello DheerajEngineer,
Regarding the activation, if SMLGR is stated as licensed then the activation is correct. As I can see from the output this is a OEM installation, meaning that the activation is provided by the manufacturer of the computer, based on the hardware install signatures.
Regarding the issue of the external acces:
-For seeing if the user is connected (no only signed on session left) you can run the next command: QUERY SESSION
-To fully logoff any users in the computer, create a .BAT file with the next inside, which will detect sessions active and then log them off
query session >session.txt
for /f "skip=2 tokens=3," %%i in (session.txt) DO logoff %%i
del session.txt
Last but not least, you can access Windows Settings and users and Accounts, and then:
-Create a new user with Admin rights for yourself
-Disable the Administrator (built-in) account
-Delete or reset password of other users that you don't use
