DevPerm

NTDEV
1

For a project I needed frequent changes of device permissions. Oddly enough, there is no tool for changing device permissions post-installation, even regedit is unusable for this purpose. So I made DevPerm, a little DEVCON like utility for managing the security property in the registry. I don’t know if that would be interesting for others. If it is, I’ll find a place to post the utility.

I also made a GUI version, with an interface similar to Device Manager. But unlike the console version, it required much more work than I expected so it is not yet really ready for production usage. Again, I could try to make the final touches if others are interested.

I might be.

Thanks,

I posted the utility, temporarily, here: http://pasti.fxatari.com/downloads/devperm-100.zip

Tested under 32-bit systems only (Win2k, XP and Vista). *Should* work on 64-bit OS as well.

An extract of the docs follow:

DevPerm is a console utility to manage Windows device drivers’ security. DevPerm can display, delete and modify the registry security descriptor both for devices and setup classes. Modifications don’t take effect immediately until the device is restarted. DevPerm can operate on local or remote computers. The command syntax and interface are similar to Devcon…
