Hello friends, I successfully installed W7 x64 SP1 Beta on my rig. No problems, smooth sailing. After about 30 minutes, I'm surfing the web, and my Antivirus (NOD32) alerts me to the fact that there are updates that need to be installed. So, I close the browser, and manually check windows update. Sure enough, there is one update available for me to install. KB2032276 is installed, and I reboot the machine. Upon reaching the desktop, I am greeted by a watermark that claims that my install is an "Evaluation Copy"...lol. Now, to be clear, this is a bios modded machine, running an OEM install, that has run flawlessly for months. I built it, I modded the bios, this thing has been nothing short of bullet-proof. I ran a -dlv command from an elevated command prompt, the report shows that the OS is licensed through the OEM_SLP channel, with 4 rearms remaining. I have an Asus Mobo, and used an Asus Cert and Key. Is it possible to be "Licensed to Evaluate"?? This is a heads-up, and a request for input. I thank you for your valuable time, Gideon Edit: I should add that I used the Windows Update Tool, and applied SP1 through Windows update. The Service Pack, as downloaded from WU was 58MB. The SP took less than 10 minutes to complete. Second Edit: I should add that on my x64 installation, this update is removable. It can be uninstalled from the Windows Update dialogue box. Click on "Installed Updates" in the lower left hand corner, then find and select the update from the "Microsoft Windows" header, then select uninstall. It is highly advisable to close any running apps in the system tray before performing this action. Please be advised that anyone who has installed the SP1 Beta can remove it the same way. I can confirm that this works my system, as I performed this action 3 times for confirmation. I can only provide this confirmation for systems updated through Windows Update. Other methods (updating through application of downloaded ISO, etc) may not be subject to this.
