Not all the meltdown patches are out yet - try getting a patch on Debian for example. Also unless your AV software is confirmed to work with the Windows patches, they just won't install at all. We run Sophos and they're not planning on certifying it to work with the patch before next week.

You're fine if you're running vanilla windows and primary Linux distos AND can have downtime for patches. Otherwise meltdown is a shocker...
