Task Sheduler Error

This problem has nothing to do with KB5034441 or the Recovery partition.

I agree with dalchina that trying to restore tasks manually is going to cause problems. I would never even try it.

Once armed with a list of the missing ones, I would unhappily export them from one computer and import them into another.
If a Repair install does not fix your problems then I can guide you through making the list and doing the transfers.
But the procedure will be long & boring and might cause a couple of errors that then need to be checked.
Overall, a nightmare.


All the best,

If there's an event id characteristic of one of the missing scheduled tasks, then the event log would tell you when that task last ran.. so you would know when the tasks were last present.

The OP has not enabled Task history in TS so there won't be any Task records in Event viewer.

And changing it does not act retrospectively, the missed tasks cannot now be made to be listed in Event viewer.

I wasn't referring to that- but to events generated in the normal course of use of the O/S.

For example, if an event was generated when a Windows Update scan ran- that's one of the missing tasks. I just can't readily think of an appropriate one.

Oh, right.
WU is the only one I can think of as well.

Probably the best idea. After all, you don't know what other damage exists.

Before you do, check your entire physical disk using e.g. Crystal Diskinfo (free). (That's quite different from chkdsk).

Of course, make sure you have a full backup of all browser-related and email client-related data, + program licenses, passwords etc etc as appropriate.

When you do clean install, start using 3rd party disk imaging to external storage as early as you can in the process and at intervals as you configure things so that should something go wrong you don't lose much.

Understood.

Just speculation
Perhaps it's your disk.
Perhaps TS is behaving properly but the disk is not being read correctly.

chkdsk - SS64
The most aggressive form of ChkDsk I have used is

Code:

chkdsk c: /R /X
