Wrong fonts in multiple browsers

[kommandante]

I have problems with many websites, where fonts are not displayed correctly. This error is showing up across all browsers (have tried Edge, Chrome, FF). I mainly find this error with Google Roboto font. The font is freshly installed. I don't even know what fallback font is used, I'd be fine , if I could just change that, but like this, a lot of websites are unreadable.

according to whatfont plugin in chrome, this should be Roboto

I have a guess, but you will have to test it. Open the Registry Editor, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes and see if there is a non-standard font substitution. 

You can also look at the source table you are having trouble with here and see if there are any strange changes.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink
