Whenever I click Alt + Arrow up/Arrow down my screen will do an unwanted flip. I'd like to disable this shortcut behaviour. I've already looked at Super User question How to stop my laptop's screen from rotating when I press Alt + Arrow?.
But Ctrl + Alt + F12 doesn't start any menu for me. How can I fix this problem?
I have an Nvidia graphic card, 2100M, and Windows 7 on a Toshiba computer.

In some obscure place off the internet I found a solution.
Run msconfig (Windows key + R), select startup and disable Toshiba 180 Degrees Rotation Utility; then, click Apply and finally OK.

Neither of these answers helped me. What I did:
Right-click on Desktop and select Graphics options > hotkeys > Disable
As indicated in Windows Forums and Microsoft Answers

1Note to future readers: This does not seem to interfere with Windows shortcuts as I was fearing it might. – emragins – 2015-12-08T17:38:10.950
remipod is correct (see also Noxoreos's answer): You need to assign different shortcuts in the Intel thing, otherwise it still intercepts the keypresses and other programs can't use them. – Timmmm – 2016-04-22T07:22:08.043

For these using Intel Graphic, to disable global hotkeys:

Normally, I am able to access the Intel Graphics from the system tray, but it was disabled for some reason. I was trying to raise and lower the volume on WinAmp, but it kept flipping the screen! – Sun – 2014-09-22T15:20:56.747
thx @dario , upvoted for saving my day :) – Ravi Vaniya – 2019-05-01T07:05:02.470

I had the exact same issue on an Acer notebook with an Intel graphics driver. Simply disabling the feature was not enough, since the keys are still captured and not passed to the system afterwards, even if the rotation did not happen.
That means I was still not able to use this key combination in any other software, because it won't receive the shortcut.
To solve this I opened the Intel graphics properties page, enabled shortcuts, changed all available shortcuts from Ctrl+Alt+(some key) to Ctrl+Shift+(some key), and finally deactivated it again. This way the Ctrl+Alt combination is captured only for the F8 key, which can't be changed, and all other shortcuts are captured by the software I wanted to use (like Eclipse or PHPStorm) - I rarely use the other combination, so this was a valid solution for me.

Perfect. I needed to do this to enable the ctrl+alt+<- and ctrl+alt+-> shortcuts for changing tab in RStudio. – jbaums – 2015-01-19T00:36:42.953

Have a look at the Control Panel for the Nvidia Desktop Software and launch it. It should bring up a configuration Menu (for screen resolution, etc.) and there should be a Menu Item to disable the Hotkeys. IIRC it is the last Item.

Will try to look at work tommorow, I've looked before but couldn't find it. Its a mobile graphic card NVS 2100M. – Warpzit – 2012-01-03T13:08:57.380
1I really can't find it. I've looked inside the nvidia control panel under display -> change resolution and display -> rotate display. – Warpzit – 2012-01-04T08:41:45.377

Ctrl + Alt + F12 does nothing. Maybe only for you? – 7h3w1z4rd – 2017-01-07T20:49:41.713
Welcome to Super User. Please be aware you have posted an answer to a question that is very old. Although there is nothing wrong with doing so, just be aware you may not get a response. – CharlieRB – 2017-01-09T12:57:42.697

If your processor is from Intel, one of these possibilities should work in your case:
Right-click on your desktop background and
select Graphics Options > Hot Keys > Disable
as illustrated in dario's answer.
Press Ctrl + Alt + F12 to open an Intel dialog box and disable the Hot Keys. You may have to change the shortcuts before disabling them as explained in the Noxoreos' answer. 
Temporary stop process hkcmd using Task manager (Ctrl + Shift + Esc) as proposed in the gavenkoa's answer. You may also stop the process igfxTray as suggested by gavenkoa. But on next reboot, this (these) process(es) will start again.
Disable the starting of hkcmd (and igfxTray):
C:\windows\system32\hkcmd.exeigfxtray.exe).

It is possible to disable hot key catching withing Intel applet (by Ctrl+Alt+F12 or from Graphic options on Desktop right click).
But I recommend to disable Intel applets!
Ctrl+Shift+Esc to start Task Manager and disable everything from Intel published in Startup tab (hkcmd module is responsible for catching keys, also igfxTray module is useless).

One of the worst shortcuts ever, which is confusing so many users who hit those keys accidentially and do not know how to get back to the default view. – Kai Noack – 2020-02-07T10:28:49.297
