Oh, it looks the installed version of rvkroots.inf is from 2014-07-14 ... so wsusoffline will update rvkroots even in the future (in case it is re-generated), and even if the support from Microsoft ended?

It will install the most recent version of rvkroots.exe. But it's not recommended to install versions, which aren't listed as compatible, as they might cause problems on wxp systems.
