I posted these instructions to the horrible Microsoft forums to help anyone who just hates unnecessary junkware that works all the time, but it should work for your purposes too. The trick is to leave the file in place, but not let Windows run it - and you can do this by removing the Execute permission from the file. With a little digging, you could probably figure out how to do this programmatically, although for obvious reasons, I would recommend not to do this on other people's computers during installation (if your program is deployed somewhere else).
Permissions are configured using ICACLS, available starting with Windows 7. (CACLS and the much older ATTRIB cannot change Execute permissions, which is all we need to change here.)
In the instructions, you will see the TAKEOWN command. At some point, Microsoft decided that you are just a visitor on your computer - Windows "owns" this file, so you usually canโt change the file permissions, so the first step is to take responsibility for it. ICACLS can also establish ownership, but TAKEOWN is actually easier to use if you, the logged in user, are the intended owner, which is what it is.
Your user account must have administrator rights to complete this task. Open a command window (press Win-R, type "cmd" and press Enter). Enter each of these commands and press enter after each of them:
%systemdrive% cd %windir%\system32 takeown /f wisptis.exe icacls wisptis.exe /deny "NT AUTHORITY\SYSTEM":(RX)
Then reboot. Poof, it has disappeared, and Windows will not be able to start it (although you can, if you really want for some reason).
If you want to restore permissions, run ICACLS with / grant instead of / deny.
Please note that a really useful Snipping tool for Windows requires wisptis, for some reason. I use it often enough to use the shortcut on the taskbar. Now I hold the shortcut for the awesome IrfanView image editing tool, which can do superb image capture using the command line. Google for all options, but I use "/ capture = 4", which launches IrfanView in capture mode to select a specific area.
