Actually, it’s been running quite well on my test machines for a pre-release operating system, but I have encountered a couple of instances in which it seemed to be fussy about what folder I installed an application into. Now it’s looking like I may have run into a major bug. Ed Bott has the news:
Yesterday, Microsoft published Knowledge Base article 970789, which provides details of a problem that affects the 32-bit (x86) English-language version of Windows 7 build 7100. The problem, in short, is that the installer incorrectly sets access control lists (ACLs) on the root of the system drive.
