I am running Windows 7, x64 RC 2 (7100) build, downloaded from Microsoft a month or two back.
Legitimate product key that I received from MS is used, and it is activated through MS as well.
Everything has been working great, this is a fresh install from 08/01/2009.
I noticed my MS Windows "Update" icon appear on the task bar, and decided to have a look, I already went ahead and selected for windows to check for updates but to ask for me to install/chose which ones.
Anyways, there was a huge list of updates for MS office 2003 (yes i know there are newer versions but I like 2003), so I went ahead and selected a few, most of them were security updates, and there was one update for microsoft silverlight.
I went ahead and installed them all, restarted, and all of my desktop icons , and task bar icons including shortcuts began disappearing, then I tried moving mouse over them and they would appear and or disappear again.
I have not messed with any hacks or tweaks to remove the logo from the "windows 7 evalutation ..." from the desktop , that doesn't really bother me so i dont mess with removing it. Besides, I don't like installing stuff that messes with my registry, let alone on an unstable build.
Moving forward, I went through the recently installed updates list, and figured one of the new updates must have triggered this new found problem.
Sure enough, it was the [Microsoft Office 2003 (Security Update)] that triggered this, I don't know why, how, or what exactly the problem was, but after I installed only that update, and restarted my issue disappeared.
I replicated the problem twice, and fixed it the same way.
Just thought this was odd, wondered if anyone else experienced similar issues with MS updates.
