I've scoured the net for the kind of app that I'm looking for, and also found an (unresolved) thread regarding it here (https://portableapps.com/node/1422), but have still not been able to find what I'm looking for.
It seems like it would be a fairly simple app to write, so I thought I might ask nicely
Basically, I'm looking for a program that will lock my workstation. NOT one that is installed on the host PC and uses the USB drive as a key to unlock it, but something which when run from my drive will lock the workstation until a password is provided, without the user needing a user account or admin privileges.
The thread previously mentioned suggested using a screensaver file, but unfortunately it seems you need a personal user account to define the password and access to alter the display settings - not to run the file, but to activate the option of prompting for a password when input is detected (at least in Windows 7).
The reason I'm looking for an app like this is that often when I spend time at a net cafe, I'm usually in the middle of downloading something when I need a bathroom break, and I don't want the hassle of closing everything, ejecting my USB and then reversing the process when I come back.
It doesn't seem as if it would cause any problems either if you forgot to disable it, as a simple hard reboot would solve the problem.
Anyone willing to help?
Thanks in advance,
