Windows 7 RTM Build 7600.16385 includes a potentially fatal bug that, once triggered, could bring down the entire OS in a matter of seconds: "The bug in question - a massive memory leak involving the chkdsk.exe utility - appears when you attempt to run the program against a secondary (i.e. not the boot partition) hard disk using the "/r" (read and verify all file data) parameter. The problem affects both 32-bit and 64-bit versions of Windows 7 and is classified as a 'showstopper' in that it can cause the OS to crash (Blue Screen of Death) as it runs out of physical memory," reports InfoWorld's Randall Kennedy. Microsoft is claiming the bug is a chipset driver issue, but Kennedy's testing of the latest Intel INF Update Utility driver set and VMware virtualized chipset drivers suggests otherwise. "This is clearly a Microsoft bug - and the fact that it manifests itself via the chkdsk.exe utility makes me wonder if it isn't something intrinsic to the Windows 7 version of the New Technology File System (NTFS) driver stack." Worse still, user comments suggest that Windows Server 2008 R2 suffers from the same flaw.
