Microsoft has made available a patch to a Windows 7 bug in the Release Candidate (RC) and is preparing to roll out some “fake” test patches to verify Windows 7’s automatic-updating abilities this week.

Microsoft posted on May 8 an update that fixes incorrect access control list (ACL) settings on the root of the system drive in the 32-bit RC version of the product. (For the gory details on this “doozy” of a bug, my colleague Ed Bott has a lot more.) More at; http://blogs.zdnet.com/microsoft/?p=2731
