So Microsoft just released an update, via Windows 7 Update. This update is labeled as KB971033 and is listed as “Update for Windows 7″. Immediately after it was published, there has already be confirmed reports of it not detecting existing activations on the computer and does not block a lot the new ones. This update detects 70+ activation bypasses/cracks but apparently that was not enough.
