How to disable windows system shortcuts programmatically

[algea]

Hi to all. I am about to make a new screensaver. I have new idea. I am going to lock all Windows shortcuts like Ctrl+Alt+Delete, Ctrl+Escape, Alt+Tab,… etc only with mouse move event I am going to ask a password. Then unlock the screen. How to do this I have no idea. I have restricted time so that asked in this forum. Try to solve this at the same time like you from net cloud. I would be much appreciated…

Just some thoughts...

Not sure I think that is a great idea. Why would someone want to have 2 passwords to access their system: once when windows starts (if required) and another one when your screensaver locks? With the way Windows works now, if a password is needed, the same password can be used to access the system on startup and again if screen is locked.

I would think creating your own screensaver that a user can select from the system list of screensavers is a reasonable choice. The choice of locking the screen is a separate item and if used, at least the user's system password is valid.

But LaVolpe, he's trying to develop one of those pay-to-unlock-your-computer deals, so he doesn't want to use the same password.

Are you actually writing a screensaver or are you writing malware?

A screensaver is more than a normal .exe, there's several steps to run as a Windows screensaver, where those things are disabled with SystemParametersInfo's SPI_SCREENSAVERRUNNING flag, then uses the VerifyScreenSavePwd API.

See this article for an example of a screensaver written in VB6.

Does anybody even use screen savers anymore?

The lock screen is far more useful, see: How to Customize the Lock Screen on Windows 8 or 10.
