problems with updates is very slow to be installed

It is possible to constrain updates - e.g. to set them to Notify only.

E.g. use Winaero's free tweaker - many tweaks, with full explanation. Or just see his site. Easy to find.

...why the automatic update does not happen automatically.

- is a different issue to:

I do not know when there will be an update because it happens automatically.

Without user intervention, minor updates are applied automatically- the absurd thing being that when updates require a restart, suddenly that could happen.

If your question is then 'why aren't they silent' (not needing a restart) that's an issue to do with being able to replace files in use or not.

As for upgrades, these follow the manner of Windows installation, and there are a significant number of prompts.

People tend to prefer these to be controlled given the history of difficulties with upgrades (and come to that, even updates).

This is especially true in organisations.

I see, unfortunately your 1st post wasn't clear enough on that, although you mentioned freezes.

First, make sure your disk and file system are ok.
Crystal Diskinfo (free) gives a quick indication.

Then from an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Make sure the result is clear or fixed- else do not proceed.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

Then again from an admin prompt run
sfc /scannow
and post the result displayed (checks system files).

When you apply updates, make sure external peripherals are disconnected.

To find what went wrong, you can try inspecting the various log files.

There are also many threads on this forum on update failures, and there will be suggestions or solutions there- I've not read those or summarised them myself.
