    Where is the Windows build number stored?

    Windows OS Builds List

    Hey guys, I would like some help from the community, this is a big project and 2+ minds are better than one, what I would like you guys to do is search google for windows 7 build strings NOT listed in my list, combine it into your own little list of missing builds to make it easier for me to add all at once.

    here is what I need you to do, search google with numbers going from
    6.1.7600.16400 ~ 6.1.7600.17023
    --
    6.1.7600.20500 ~ 6.1.7600.21200
    --
    6.1.7601.17652 ~ 6.1.7601.17841
    --
    6.1.7601.21702 ~ 6.1.7601.21994

    searching each number 1 by 1 by myself takes a long time and this community effort will help make this list 2x longer , also when you search make sure the number isnt already listed in my builds list please, and include the full build string please.

    I would like to see the builds you list in this format:
    6.1.7601.21991 (win7sp1_ldr.120509-1511) you dont even have to click on the google links the build strings are revealed in the description, if the build itself is real of course xD

    this effort will be greatly appreciated xD!
