My Dad's computer, which runs Windows 10, somehow has gotten stuck with inverted colors (so everything appears as a negative) as a default.
Using the Magnifier function
Windows =, I can trick Windows to show the normal colors by inverting the colors
Ctrl-Alt-i. However, this is only a temporary remedy because as soon as I close the magnifier, the colors return to inverted/negative. I've also gone to the Ease of Use settings to no avail.
In an attempt to make this permanent, I went into the registry and looked at the
Computer\HKEY_CURRENT_USER\Software\Microsoft\ScreenMagnifier : Invert key. It was set to
1, so I changed it back to
0 but the screen didn't change. The registry change has persisted through reboots, but the screen colors remain inverted.
It appears to me that Windows doesn't realise that its already in inverted mode.
Anyone know how to solve this problem?
