When collecting process information in Windows 2012 Standard (not R2), errors like these appear and no data is collected:

2018-06-06T00:24:46.637+0530 ERROR process/process.go:454 Error getting process details. pid=620: error getting pr
ocess arguments for pid=620: ProcArgs failed for pid=620: could not get Win32_Process WHERE ProcessId = 620: Exception o
ccurred. (Invalid class )

It doesn't seem to happen in more recent versions of Windows Server (at least it doesn't happen in 2012 R2 and 2016), we already have a check for Windows Vista, maybe we need something else, although the documentation mentions that it is supported since Windows 2008.
