    After just installing 5 security updates for several .NET Framework versions my boot time for XP increased by up to 2 additional minutes. I did a System Restore and the boot time went back to normal. I then installed each one singly, doing a System Restore in between each installation, and each update increased the boot time by 1.5 to 2 minutes. The updates involved are:

    .NET Framework 2.0 SP2 (KB2863239)
    .NET Framework 3.0 SP2 (KB2861189)
    .NET Framework 3.5 SP1 (KB2861697)
    .NET Framework 4 (KB2858302)
    .NET Framework 4 (KB2861188)

    Any ideas? :confused:

    Hi daddyo. I don't believe its the updates that are causing the problem but rather the .NET Framework services are probably increasing your boot time. The .NET Framework updates set the .NET Framework Services to Automatic so those services are probably running on boot up. Install all of the .NET Framework updates then after they are installed click Start< Administrative Tools< Services. After the Services window opens set the .NET Framework Optimization Service and the Microsoft .NET Framework service to disabled. Then reboot the computer and see if your boot time has stayed the same.

    Hi Evan, thanks for your prompt and helpful response. I disabled the Microsoft .NET Framework Service as you suggested, and that seems to have eliminated the slow boot. I was unable to locate the .NET Framework Optimization Service, however. Funny thing is though, I have 2 other desktops running XP (1 running XP Home and 1 running XP Pro) with the .NET Framework Service set to Automatic, and neither one of them had any adverse effects from installing any of the .NET updates. And don't I need that service running?

    No. the .NET Framework service is optional and is not required to be running.

    Unless you are using applications that require that service to be running which most home users won't be anyway then you can leave that service disabled with no ill effects.

    If I do have something running that needs it, how will I know? And what type of app would likely need it?

    If you are running an application that does require the service to run which I seriously doubt then it will not run correctly. But it would just be a matter of re-enabling the service and testing to see if the program runs with the service re-enabled. Just make sure you keep track of what services you disable in case you need to re-enable any of them in the future.

    In my years of dealing with computers I've never come across a program that requires that .NET Framework service to be running. Besides, that service improves performance of programs that rely on the .NET Framework architecture so it doesn't do anything too important.

    Can I just uninstall those .NET Framework apps then if they're not needed? Somehow the .NET Framework service gets reset to "Automatic" occasionally which, of course, kills my boot time again.

    Yeah the .NET Framework updates will reset the service back to Automatic. But the .NET Framework components are required for some applications to function properly such as some system drivers so you should not remove it. However the .NET Framework NGEN service does not need to be running for those programs to function.

    How about setting the service to "Manual "? What would that do?

    Yes you can set it to Manual and see if it still starts up but I've disabled this service on hundreds of computers that have .NET Framework installed and have noticed no side effects.

    Yeah no problem. :)

    Do you have any other questions or would you consider this thread resolved?

    I guess I can consider it resolved, although I don't really understand why this is the only one of my PCs affected and why it only popped up after that latest batch of .NET updates was installed. Just another one of life's little mysteries I guess.
