Just barely a week after Microsoft officially made available Windows 7 RC download with the build version of 7100 publicly, a newer build of Windows 7 has been compiled by Microsoft and released to internal testers. And of course, the Windows 7 build 7127, which is post-Release Candidate build on the RTM-branch of Windows 7 operating system development tree has also been leaked to BitTorrent (BT) network, in the form of complete ISO files.

Microsoft has specified that there will only one and final release candidate available officially before the final RTM general availability release of Windows 7. Thus, unofficial leaked post-RC builds are the best shots Windows 7 enthusiasts can get a hand on the newer interim build of Windows 7. However, Windows 7 Build 7127 appears to not much different from Windows 7 RC build 7100 in term of user interface. However, there will be bug fixes and under the hood changes.
