Question: I'd like to disable `ctrl`+`alt`+arrow keys changing the screen orientation. I've seen [here](https://superuser.com/questions/279756/how-to-disable-the-screen-orientation-hotkeys-in-windows-xp) that this is a function of the Intel graphics driver. So I followed the directions and `disabled hotkeys` in the `Intel graphics card control panel`, but the hotkeys are still `enabled`. Might there be some other program controlling this? I'm running a Lenovo T420.

Answer: 
I see several people referred to the Intel HD graphics driver, but without much in the way of instructions, so perhaps this will help. (Note, this response is partly based on this answer: <https://superuser.com/a/592688/197972>).

On my system (Windows 10, Intel HD Graphics 5500, driver version 10.18.15.4281, dated 8/31/2015), the answer is:

1: Launch the *Intel HD Graphics Control Panel* (it's on the start menu).

2: Click the icon labeled "Options and Support":

3: Under the "Manage Hot Keys" section, click "Disable":

4: Click "Apply" to save the changes.
Steps
1-Move the mouse to the screen & right click (you will see View, Sort by, Refresh, Graphics Properties...point to Graphics Options & Select Hot Keys.
2-Select Disable.
3-Now if you try to press [Ctrl] [Alt] + Arrow Keys the video screen wont rotate any more. For some reason you want to control screen rotation just Enable it again.
