I am looking for a program which would allow me to login to my pc once i put valid serial key/serial no.
The serial key/no. would valid until the last of every month and a new key can be generated for the particular month.
Actually i want to restrict my user to use the computer until or unless they submit some documents on 1st day of every month to me.
Thats why i want this kind of program. Once they provide me the required documents then i would share the new serial key/no with them and they can use that serial no for the whole month.
Again on the first of next they would submit the required documents to me and then i would share the new serial no to them to access their PC.
I hope i made my points clear.
Thank you in advance.
