The user is reporting strange font corruption.

 

Sure enough, I logged on with TeamViewer and took a screenshot.  Here's what I see:

 

 

Anyone know what caused this and how to fix it?

Not having seen that particular corruption I'll make a wild guess and say that something (possibly something the user ran in order to try to change his UI characteristics) messed up the [HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics] key contents.

 

Here's one I use to set Windows 8 and higher systems to settings I like...

Thanks, I'll give it a shot.

It's probably a font substitution issue (since the taskbar is messed up too.) Try restoring the attached keys.

 

DefaultAllFontKeys.reg

 

Edit: If that doesn't work try restoring the font links: HKLM.FontLink.backup.reg
