How to implement access to a PC on windows on demand?

Question

Windows

There is the following task: when you turn on the PC, access should be blocked, and issued by permission, like launchers in computer clubs .
But there is a small catch, the issuance of permits can occur from anywhere in the world, through a web interface or something similar.
I have experience in frontend / backend development, tell me where to dig or maybe there are ready-made solutions?

Looking what blocking is meant. "Launchers in clubs" only made the appearance of blocking, preventing games from starting. In total, you have software on a PC that does not allow you to do anything other than what the launcher itself allows you to do (run games). Those. he is a shell. It receives an http request (if you like), the lock is released. Everything.
If you want to implement session locking, then you should study winapi, which will allow you to remove and set the lock. You don’t need to set up a mind block much, but entering a session is not an easy task. One way or another, this can be done and not necessarily using php or other popular backend scripts, but for example, write software in C ++, Delphi, C # that will allow you to set and remove the lock through the startup parameters of this software. ("lockapp.exe -lock", "lockapp.exe -unlock") And only then call this software through php.
