Thanks, I already did the download and reinstall Windows 10. The same error message keeps occurring and I cannot figure out why and what I need to do to get the service out of the pending stage.

Your above statement does not make sense.
Doing a reinstall formats the drive before installation, suggests your ISO was faulty.
If you have an M$ account and have synced to the cloud you could do a clean install, all your files and settings would be restored.

My thoughts exactly and why I asked where the ISO was downloaded from.

It is morning now and I followed your Repair Install instructions except for the disk cleanup - the error message is still the same - it seems like there is a problem with one of the updates, I think it is KB3211320. Here is a copy of my Windows Update Log (file to large - 2 logs) and copy of registry. Attachment 122558 Attachment 122559

FYI, when I do a reinstall of windows I only use the files from this site - https://www.microsoft.com/en-us/soft...load/windows10

If you think it is that update, try this tutorial to uninstall it. Windows Update - Uninstall in Windows 10

Other than that, I am not sure what the problem is. Hopefully someone else will be able to help.

KB3211320 is a servicing stack update from Jan 24. It replaced another from Oct 27th, which replaced another from back in Oct, and so on and so on. I would try going into Uninstall Updates and uninstall all of these he can find. Reboot and see if it fixes itself. He may have had one botched update that has tainted the rest.

Also found this relating to that error code.

0x80040154 is a typical 'class not registered' error message. It occurs when PC users try to register and Run a 32 bit dll (dynamic link library) Windows programs on a 64 bit version of Windows.

If the OP could do a WINVER and post the pic, it would help.

WIN KEY + R, type WINVER, hit enter. Post pic. Hope he doesn't have 32-bit and 64-bit stuff co-mingled somehow.

And this page from settings:

Sorry for the late reply. My computer crashed and I was rebuilding it today. I am taking the updates one at a time to see which one is causing the problem and will uninstall it. Here are the screenshots of my system.

Good morning, @kaltland

Thanks for the system info. Rebuilding? Does that mean a clean install, or something else?
