Automatically turn on grayscale mode in windows 10

Question

I want grayscale mode to turn on at a specific time every day, then turn off automatically a few hours later. I know ctrl + windows + c can be used to do it manually but it would be great to automate the process such as turning on at 9pm and off at 7am for example.

It is possible. You need a tool for sending the keys ctrl+windows+c and a way to schedule this sending. These tools are:

AutoHotkey
The SCHTASKS batch command, or alternatively the Task Scheduler.

You will need to create a AutoHotkey script to send the key combination, which is a one-liner file with the .ahk extension:

send, #^c

You will need to schedule its execution at the days and times that you wish, using the SCHTASKS command or the Task Scheduler.

You may also disable the hotkey ctrl+windows+c by changing in the registry the DWORD item HotkeyEnabled at the key HKEY_CURRENT_USER\Software\Microsoft\ColorFiltering. Its value is 0 to disable and 1 to enable, and the modification takes effect immediately. You may do so programmatically by either using again AutoHotkey with the RegWrite command, or by using the batch REG command.

Apparently, Windows 10 doesn't officially support automatic grayscaling depending on the time yet. You can try suggesting that to Windows through the Windows' Feedback Hub.
