Server 2003 Enterprise R2 with Service Pack 2. While installing this month's critical updates, we received a pop up from the "Windows Security Alert" asking if "Do you want to keep blocking this program", Name : Windows Service Pack Setup, Publisher: Microsoft Corporation. The updates install regardless of the button I hit but take 15 minutes a piece to install. If I install the updates manually, they install immediately but hang the same amount of time while "performing cleanup". Did the July or August updates change something? I am running a fail over cluster.

Hi, Sometimes the update process seems to be hang at performing cleanup when the size of the update is big. We only need to wait patiently and it will continue to install the update. So please wait more time to see the result. If it still hangs, I suggest temporarily disable or remove your anti-virus programs. In addition, lets disable all startup items and third party services when booting. This method will help us determine if this issue is caused by a loading program or service. Please perform the following steps: 1. Click Start, click Run, type "msconfig" (without quotation marks) in the Start Search box, and then press Enter. Note: If prompted, please click Continue on the User Account Control (UAC) window. 2. Click the "Services" tab, check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray). 3. Click the "Startup" tab, click "Disable All" and click "OK". Then, restart the computer. When the "System Configuration Utility" window appears, please check the "Don't show this message or launch the System Configuration Utility when Windows starts" box and click OK. Please test this issue in this Clean Boot environment, if the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue. If the issue still occurs, please let me know what update you are trying to install. Meanwhile, please send me the windowsupdate.log and system information files for further research. Note: There are two Windows Update log files with similar names, we will be using the "WindowsUpdate.log" file without a space in the middle of the name. 1. Click on Start, Run and type "WindowsUpdate.log" (without the quotes) 2. Click on the OK button. We will see a file named "WindowsUpdate.log" 3. Now click on the "File" menu and then click on the "Save As" and select "Desktop" in the "Save in" option on the top of the window. 4. Click on the Save button. The file will be saved to your Desktop. 5. Upload this log to the following site: https://sftus.one.microsoft.com/choosetransfer.aspx?key=d1603763-f1c3-4fcb-9646-057168e39482 Password: qRP0XzYkn00% The System Information can provide us with more information about the current status of the system. I would like to check it for you. Please send it to me using the following steps: 1. Click Start, go to Run, type in "MSINFO32" and press Enter to start System Information. 2. On the popup window, on the menu bar, click File, and click Save to save it as an NFO file, such as system.nfo. 3. Upload it to https://sftus.one.microsoft.com/choosetransfer.aspx?key=d1603763-f1c3-4fcb-9646-057168e39482 Password: qRP0XzYkn00% Hope it helps. Tim Quan - MSFT
