The problem affects both 32- 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.

The bug also appears in Windows Explorer when you run the integrated disk check utility. In each case, the utility executed the first three stages of the test correctly using modest amounts of memory (several hundred megabytes).
