Sumatra is lightning fast and I like it more than Evince, which I used before.
One thing that bugged me was the ugly yellow background. It makes the tool and unfortunately also it's website look unprofessional. Here is how you can change that - at least the tool, not the web site ;)
- Start SumatraPDF.exe at least once. You may have to "open with..." it with a pdf file first.
- Fire up regedit and find (Strg+F) "SumatraPDF.exe". You need to find a key named: HKEY_USERS\...\Software\Classes\Applications\SumatraPDF.exe\shell\open\command
- There you should find a value named: (Default) that points to your Sumatra executable (see my screenshot)
- Double-click the (Default) value and add: -bg-color 0xffffff between the "...SumatraPDF.exe" and the "%1" (as in my screenshot)
