Can't type into these fields at all, but can type in Outlook, Chrome etc and every where else. Various other issues with the desktop, Microsoft Support remoted into it and told me the next "rollup" update will fix it all?? The current rollup KB4015438 x64 installs then after the reboot fails and uninstalls all changes. Taskschd.msc also doesn't work, comes up with errors whenever you try to look at the properties of any of the tasks. Also, can't type into Edge..

Hi Quinco,

What version of Windows 10 Mail app are you using?

To check, open the Mail app, then in bottom left click the Cog icon then select About

The latest is Version 17.8021.42367.0

If you have something earlier then open Store and in top right side either click the Down arrow or Check for updates button and update your Windows apps.

Regards,

Fixed by system restore, then doing the update that would not install previously. Only problem left is Taskschd.msc not working properly, when I go to properties of any tasks, it give this error.

Would you be able to type or copy & paste the following into a Command Prompt

Code:
REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMC\SnapIns\FX:{c7b8fb06-bfe1-4c2e-9217-7a69a95bbac4}"
Press Enter key to execute.

Now adjust Command Prompt window so you can read all the resulting data displayed then press Alt and PrtScn to take a screen capture.

Now open Paint and paste the capture here then click Crop and finally File > Save as

Then upload image here so I can take a look at the results please.

It's possible a MMC key has become corrupted or is missing altogether.

It's also possible a Task created by the installation of a third party application has become corrupted, or is orphaned since the removal of that application, which can also trigger this kind of event.

There are some circumstances when the .Net Framework machine.config files are corrupted which can also trigger this scenario.

The point being it may take a little detective work your end to resolve this without reinstalling Windows.

OK thanks for that.

The Registry Key is normal, so no issue there.

That leaves the possibility of an orphaned Task, or an existing Task being corrupted.

To verify whether a task is orphaned, you'd need to review Tasks via the Task Scheduler that have been created by third party programs; for example a security program that creates a task to scan your hard drive when idle.

Once you confirm which tasks you currently have which were created by third party applications, you can then review the Registry TaskCache to see if the records there match your list, or there are any extra values. An extra value would be your orphan and can be deleted.

If you right-click on Start and select run then type regedit and click OK and click Yes to User Account Control prompt you can then in the left pane of the Registry Editor window expand the keys to this location:

HKEY_LOCAL_MACHINE
— SOFTWARE
— Microsoft
— Windows NT
— CurrentVersion
— Schedule
— TaskCache
— Tree
That ought to give you a quick list to Tasks you or a third party application created to compare with the list you made.

Inside the Registry Editor you will notice just above the Tree key is another key named Tasks. If you expand that Tasks key you'll see a long list of {alpha-numeric} IDS each of which points to the many tasks that are by default part of windows, but also may contain some third party items. If your error messages ever provided a {alpha-numeric} name of the Task not working, then it will be located here and can be right-clicked > Deleted to resolve an issue.

I deleted the taskcache and tree keys to remove all tasks, then created a new simple task and still get the same errors..

Have you run a System File check or a Restore health pass via Command Prompt (Admin)?
  • sfc /scannow
  • dism /online /cleanup-image /restorehealth
