I've got Windows 7 beta 7000 installed on my laptop (Acer5520G 402G16Mi, 15.4'' screen,AMD Turion 64 x2 1.9 , 2 Gb RAM DDR2, nVidia GeForce 8400M G 128Mb DDR3). There's a multiboot with Vista Home Premium Pre-SP2 (rev.113), but I suppose that doesn't matter.When I try to install any kind of update for Windows or its components (e.g., KBxxxxxx, Windows Defender base, Windows Update's version update, Silverlight update etc.)and make a restart,I've got the following bug:All Windows Explorer'swindows got frozen. I mean, it's not possible to resize, drag, minimize, maximize, close them.When I bring my mouse pointer to Windows Explorer's control buttons, instead of the appropriatehints (Minimize, Maximize, Close), there's a small empty yellow area of 2 or 3 pixels width.When I after thattry to open Microsoft Management Console or at leastany of its components (for example,Device Manager),I see the following messagebox appearing:"Microsoft Management Console - Cannot create empty document" and on the buttons of this box there's no inscription (the "OK" text issupposed). Well, now about what I did to try to fix that.If Iopen "Programs and Features" > "Installed Updates" and uninstall these installed updates - that DOESN'T WORK. The only way out in this situation isgoing to Restore Point via System Restore and turning back to the date when none of the updates were installed. At the same time, when I update drivers for my laptop's hw (video card, motherboard, lan, and so on) or when I update my MS Office - everything is ok. No freezing happens.So, I'd be grateful for advices about how I can completely fix bug hereof.

Thanks a lot for such an excellent manual, but actually this bug was referring to build 7k only. Since that time, I've got builds 7048, 7057, 7068 and finally now 7077 installed - winupdate is working perfectly on 'em all.

Just so you know...Builds 7048, 7057, 7068 and 7077 leaked builds that were never really meant for general public consumption. They were leaked by parties unknown who probably violated their NDA... These builds were designed to test various fixes for issues and while they MAY fix some issues, they may (and likely have) introduced other bugs and issues into the OS. As such, for future reference, you won't find any support here for any build other than 7000 and the official Release Candidate - whenever that actually gets released into the wild.The offiical word on all this can be found here.
