All solutions I have seen here are OK! (Just OK!), because user (like us) can easily manipulate registry. If you are playing with Power User, s/he will beat you!

5 solutions

I don't know about removing power but you can lock volumes with DeviceIoControl() with the FSCTL_LOCK_VOLUME which means that your process has exclusive access to that volume. Take a look at the documentation here. You could do this with the CD drive.

You can disable USB ports from the registry (which can be done programatically); take a look at this article for more info.

Hope this helps,

To disable USB ports, check this[^]. You have to programatically access the registry and set the key.

Modifying register is simple, so anyone can do this.
I found a way to disable the CD ROM using regedit. Now I am not sure how you can use it in VC++ but you can atleast havea look at the way of disabling it through regedit
 
To Disable CD-Rom
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom
Double Click on AutoRun and change the value to 0
This will stop it from automatically starting.
If you double click on start and change the Value to 0, it should disable it.
 

Also I found the following link where there is a discussion and a zip file which explains how to disable CD ROM using VB.NET. Ma be that will also of some help.

Hope this was helpful.

//Disable Usb in c# 
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 4, Microsoft.Win32.RegistryValueKind.DWord);
 
//enable USB storage...in c#
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 3, Microsoft.Win32.RegistryValueKind.DWord);

Do you seriously think that the OP has been waiting for 4 years when the question has already been answered?
