When one tries to install Debugging Tools for Windows as a Stand-alone Component, there is the possibility to download ISO images of the "Microsoft Windows SDK for Windows 7 and .NET Framework 4". The 3 ISO images are called


The pattern is clear, GRMSDK<microprocessor architecture, defaulting to x86>_EN_DVD.iso.

SDK must be Self* Software development kit, EN is English, and DVD is just digital versatile disc.

Based on experience with other MS components, GR probably stands for General Release. No idea about the M though. Microsoft, perhaps. –  Harry Johnston Oct 24 '12 at 20:37
@HarryJohnston is this a best guess, or you know some product that uses this or very similar notation? –  naxa Jun 3 '13 at 19:06
GR (general release) and LR (limited release) are common MS abbreviations, particularly in the context of updates/patches. Other than that, it was just a guess. –  Harry Johnston Jun 3 '13 at 21:43
It probably stands for Gold Release Master: "[Once] a software product [goes gold (i.e. enters the release to manufacturing phase) it] is ready to be delivered or provided to the customer. [...] A copy of the RTM build known as the 'gold master' or GM is sent for mass duplication." Source –  and31415 May 25 '14 at 23:28
