Cortana registry setting?

In that case, you should be able to do a repair install of Windows 10 without losing anything to hopefully fix it.

I have already done upgrade using ISO, "Keep personal files and apps " option but that didn't fix this.

As a test, what options do you have available when trying to do Option 1 in the tutorial below?

Do you have a "Show Cortana icon" or "Show Search icon" in the options?

No Cortana, only search.

That usually indicates that Cortana has been disabled.

If this is the case, then you might see if enabling Cortana using an option in the tutorial below may have Cortana available again afterwards.

I am not disabled on ANY of these.

I think there is a corruption somewhere in my registry setting...

Or do you know if there are services that Cortana need in order to run, I may have accidentally disabled? If so, which services are these?

Brink said:

The "Windows Search" service would need to be running and set to "Automatic".

Nope that was not disabled, it's running.

Really strange...

Maybe these could help, or not I don't know. But it looks like it's related at least the first few.

Code:

The server Microsoft.Windows.Cortana_1.8.12.15063_neutral_neutral_cw5n1h2txyewy!CortanaUI.AppXd4tad4d57t4wtdbnnmb8v2xtzym8c1n8.mca did not register with DCOM within the required timeout.

This computer is configured as a member of a workgroup, not as a member of a domain. The Netlogon service does not need to run in this configuration.


The CldFlt service failed to start due to the following error: 
The request is not supported.

Other than a clean install of Windows 10, I'm not sure what may restore Cortana.

That sucks. Somewhere in the registry, it's messed up. I just don't know which it is, and sadly Microsoft has never released such tool to fully diagnose, fix or reset Cortana to it's factory settings.
