    Task Manager does not launch from Ctl-Alt-Del


    Doing Ctl-Alt-Del brings up the blue screen with Task Manager as the last option. Clicking on it removes the blue screen but does not launch Task Manager. I can run Task Manager using Window + Run but I'd like to get my system back to running as it should. Has anybody solved this problem?

    New laptop - one week old, running Win 10 Pro 1903.

    Thanks

    Does Ctrl+Shift+Esc work?

    Searching about this brings up one utility from Windowsclub, but I don't know it, back to it later

    Check system health (in admin command)

    sfc /scannow
    Also, Taskmanager can be disabled in Group policy. Chech the registry, if there is a key called DisableTaskmgr in
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System.
    Value should be 0

    It would be good to know Laptop model. Some manufacturer utilities could interfere with system

    If all fails, perform a Repair Install Windows 10 with an In-place Upgrade

    "Does Ctrl+Shift+Esc work?" - no.
    "sfc /scannow" - done this and no errors reported
    "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System" - there is no entry for System in the Registry. So I think I have a seriously messed up registry. I am going to "go back to a previous version''. I'll probably use the Recovery partition and go back to the beginning.
    Incidentally my laptop is a Dell XPS 15.
    Thanks for your comments.

    Paulo,

    STOP.

    That Registry key does not necessarily exist in all systems so there is nothing to indicate that you have "a seriously messed up registry". I do not have it, just by way of example.

    Personally, I would try a Repair install. Despite its name, this is a repair operation not a reinstallation. See Repair Install - TenForumsTutorials
    [I can now see that AndreTen also suggested this.]

    Well that's useful to know. However I had already decided that I would execute the recovery operation to reset my pc to its factory state. I'd put all my programs' installers and data on an external drive so reconstituting my set up is fairly straightforward.
    Thanks.

    A repair install is a very useful repair technique to bear in mind as your system matures as it keeps all progs, data and most settings.

    This forum also very strongly and repeatedly advises the routine use of disk imaging. E.g. Macrium reflect (free) + external storage for image files.

    Given a disk image of Windows (or any disk or partition) you can restore that to a previous good state relatively quickly, even if your disk has to be replaced. Best to create a base disk image as early as possible.

    Only weakness- if the problem is actually longstanding, it will exist in a recent disk image. So best to support this with data backups of key data and keep data off C: as far as possible.

    @dalchina

    I agree wholeheartedly. I've been using Reflect on another computer for some time. As far as the recovery is concerned I am making disk images after every major change.

    Hi.

    If you perform a clean install and I mean clean, you should perform a full backup image on this OS when it is completed.
    This way it acts like a template as you restore and test your configuration very slowly.

    Idea is to limit the number of variables involved.

    Hope this helps.

    I've done a back-to-factory-settings reinstall so my laptop reverted to the state it was in when delivered to me. I've reinstalled all my software so everything is now fine.

    Great! Don't forget the full backup.

    Cheers!
