Wuauserv registry keeps getting deleted everytime i restart.

As you can see from the first screenshot sfc /scannow repaired some errors.

So i restarted my pc and did the scan again and it seems to find errors again.

Ill try and let you know some of those solutions you have listed.

Btw my brother said it was this application that started these problems: https://pinapfile.com/download/2d45c953191da89bfcaa37cdb5d09b5b.html

I dont recommend you to run this program but if you find a fix for it id be very grateful.

Dev, did you run SFC until it came up clean to know for sure broken System Files are fixed?

Also run DISM from Step 10 in checklist here:

I'll give you everything possible for fixing failed Windows Updates, so that at least something will work before you work through them all:

Some Updates will sort themselves out in a few days so I'd wait to see. If not or they are bothering you then here are steps you can take:

1) There is a new guided walk-through from Microsoft for repairing Windows Update that leads up to resetting components if necessary:

https://support.microsoft.com/en-us/help/10164/.... Try running that first.

2) If that fails try manually resetting Windows Update Service:

Open administrative Command Prompt and type following commands one-by-one followed by Enter key.

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

Ren C:\Windows\System32\catroot2 Catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Close Command Prompt and see if Windows Updates works then

3) You can also install the Updates manually that fail to install which are logged at Settings > Update & Security > Windows Update > Installed Update History, and then search for those to download and install from this Catalog:

A running log of Update History with known issues is here:

4) If they continue to fail and interfere, then you can block them using one of these methods:

5) If problems with Updates have become chronic and especially if you have other performance problems, go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue
with the other steps to go over your install most thoroughly.

6) If nothing else works then do a Repair Install, by installing Media Creation Tool, open installed Tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance
to the latest version 1909 while I'm here to help you with any issues with it.
