<Probably time for a complete Windows Update reset
That is what I did, and it helped. Thanks for help, everyone.

I tried it again. This time I said download only. Then I did Download and Update. It did start update. I wasn't watching what it was doing, but when I got back to the computer it was a message saying...

I ran the Download and Update using this tool. In the log it shows: Downloading updates: Succeeded with errors (0x00240003). What do I do with that? Also what location it's downloading into?

Yes, there is windows.old folder there but it's empty.

Maybe I did, although I dont remember.

I dont see any rollback under Advanced options.

Yes, it is installed. Here is what I am talking about:
195677

It says: Status:Pending restart. I am restarting, but nothing happens. It goes through normal restart and that's all. Any idea?

Thanks

Great!, thanks for all the help provided.

Yes, I extended my C dive over all partitions on the right. Restarted the computer and everything seems to be working. Can I do the same to the partitions on the left side of the C drive?

Do you mean merge all these partitions:

Also I can only merge two partitions at a time. Is that how I do it?

Yes, I can boot from my old drive (which disk 3 now). Are you asking that in case something goes wrong with my disk 0?

What about the left of drive c?

I cloned disk 3 which was Disk 0 into Disk 0 which was Disk 3. That's why they match. Here is the full screenshot:

Alright, here is a better picture:

Here is a picture of my Disc 0:

How can I use Unallocated space and all not needed partitions including J? This is where I have my C drive and I like to make it as big as possible.
...

I dont, but I sure can create it. If I put in on an USB drive how much space does it need?

Can I use Windows 10 installation media that have on my USB? I guess Repair/Fix startup problems?

Ok, here is the situation. I have removed my old drive and connected the new one to the same connector. Now bios recognizes the new drive as bootable. But.... not that fast. Here are some pictures of...

<just disable secure boot
Can you please elaborate on that?

I was wrong. The source does have all these partitions.

After the clone I see a number of partitions on my new drive that weren't seen on source disk. Why is that?

Thanks

Ys, I am going to swap drives and take disk 0 out. If Bios takes the new one as boootable then it is all I need. Will post tonight.

I will reformat my current drive as soon as I get the new one working.

I dont need dual boot. All I want is to boot from the new drive and have as C: in order to continue using all apps.
I didn't swap the drives as you are suggesting but I went to Bios to change the...
