My "Windows Update" isn't in my Services.

Welcome to the forum What service are you looking for WSUS

wsus dont you have that

Hi, have you tried searching the Tutorials section? It really is worthwhile spending a little time becoming familiar with this huge resource, illustrated with screenshots and links from one tutorial to related tutorials below the main text.

I found this for you:
Restore Default Services in Windows 10

It may help.

Sometimes you may need to restore a service back to default if you mistakenly deleted it, missing, or made changes to its General, Log On, Recovery, or Dependencies properties settings causing an issue.

This tutorial provides you with registry downloads to completely restore any of the default services and their settings in Windows 10.

Find the one for Windows Update, follow the instructions. Restart as necessary.

=================
If this has recently happened, you could also have tried using a System Restore point.
As Windows only creates thes infrequently, I have one created on a daily schedule. Tutorial available- in the searchable Tutorials section.

Note: System Restore usefully complements the regular and routine use of 3rd party disk imaging using a free or paid program and large enough external storage for sets of image files.

That gives you another way to restore your working environment even if your internal disk fails or is affected by ransomware for example.
