Disabling the “Fix Apps That are Blurry” Prompt in Windows 10

I was asked to try to suppress this error message popping up on our kiosk display monitors. When Windows 10 detects that a non-optimal display resolution is being used, it offers the end-user some help. I get why Microsoft is doing this: it is in their best interest to try to help the end-user fix problems on their own whenever possible. However, in this case, it’s a kiosk computer with no keyboard or mouse. No one will ever be able to answer the prompt and due to the size of the display, it’s always going to use a non-optimal display resolution. The prompt doesn’t offer an option “Never ask again”. Off to Google, we go!

Well, that wasn’t so easy, but I’ll get to the punchline and tell you the solution.

reg add "HKCU\Control Panel\Desktop" /v IgnorePerProcessSystemDPIToast /t REG_DWORD /d 1 /f

That command prevents the “fix the blurry” prompt from ever rearing it’s ugly head again. Now the fun part is…where is that documented? It’s nowhere documented at Microsoft’s site. In fact, go ahead and Google IgnorePerProcessSystemDPIToast. You will find very little information on this word. At the time of this posting, that was exactly 7 hits on Google. 7…out of billions of web pages!

One of the more intriguing results was this web site with a bunch of undocumented hacks for Windows 10.
