Disable Windows Magnifier

Soon after Netflix added profiles I started using one, unfortunately the Windows Media Center plugin has not been updated to use profiles and likely never will. At first I tried the Kylo browser plugin for Media Center but it was a bit difficult to use with the remote. So I’ve been using a little program called RemoteKCWin7 that allows you to make the Media Center Remote control act as a mouse or keyboard.

This has worked well with one exception. When I accidentally press the clear key Windows Magnifier would come up and then I’d have to get up shut down magnifier and rewind the show (happens frequently since the main mode key, *, is right above it). Searching around I found a lot of people accidentally starting the screen magnifier and wondering how to truly disable it. For those people the problem is that Windows 7 has a hard wired shortcut key of Win + Num Pad Plus. FYI – Microsoft does not mention this hard wired shortcut in its official page of shortcuts, Microsoft.com – Windows 7 Keyboard shortcuts.

Some applications use Ctrl + Num Pad Plus for zoom so it’s easy to accidentally hit the magnifier shortcut. The only way to disable magnifier start from the shortcut key is to rename the Magnify.exe which of course isn’t easy because it is a system file. This post, Tampa Bay Times – Solutions: Getting rid of the Windows Magnifier, has good instructions on how to get this done. However it didn’t work on my Win7 x64 Pro. Browsing the file system I found that on Win7 x64 there is second copy of Magnify.exe in WindowssysWOW64, a 64bit version I assume. By following the disable instructions I finally got both copies disabled and the keyboard shortcut is truly disabled. Although it doesn’t apply to me here’s instructions for Windows 8, Permanently Turn Off Windows 8 Magnifier.

If the magnifier is starting at boot time then you need to change ease of use settings as detailed in this long thread, Microsoft Community – How do I disable the Windows 7 Magnifier?.

Believing I had this all sorted out I was surprised the other night to have an error message pop-up when I accidentally hit the clear key on my remote. Reading the error message it was clear that the error message was coming from RemoteKCWin7 which is an  AutoHotkey application. Since AutoHotkey is my language of choice for writing tiny utilities for Windows I decided to look at the source code to see what was up. Unfortunately I had never downloaded the RemoteKCWin7 source code for the version modified to work in Win7. So I went looking for it, that’s when I found out about the loss of all the old code links when AutoHotkey moved from a .net domain to a .com domain. Searching around I found out that a number of AutoHotkey users had gathered up and archived all of the old source code and applications. Thank you to all the users who gathered up all that useful code it helped me solve the problem.

Reading through the source code I found that the clear button acts as the keyboard Esc key. The code was set to start Magnifier on the first press and close it on the second press. Trying it out I found that unfortunately on my PC the second key press only closed the Magnifier tool bar dialog not the magnified view window. So I commented out the code that starts magnifier, re-compiled it and voila, no more magnifier from the remote. You can download an archive with the source code and executable from here.
