Windows 10: Windows Store 0x80070005 Error, tried multiple fixes which didnt work

As suggested from the title I've been battling with this error for a while now.
I am not sure when it started but this Windows 10 installation was a clean one directly from an .iso file from Microsoft meaning no tampering was done with it.
It is a legit activation from the start, so no tampering there either.
My Windows Update works (actual system updates), but any updates/installations regarding Windows Store just refuses to work.
I've tried multiple fixes I've found online:
Relogged in the Store - achieved nothing
Tried wsreset - achieved nothing
Took ownership and tried switching it around multiple times - achieved nothing
Removed registry keys as suggested on another thread - achieved nothing
Tried sfc /scannow - achieved nothing (it did find a dll file it tried to fix regarding gpu drivers but thats another problem in itself)
Tried running apps.diagcab (not the latest diagnostic app but it provided info which the latest one did not)
Interestingly enough it showed a problem:
"Service registration is missing or corrupt"
It ofcourse failed to fix it and now I'm stuck with no idea how to proceed further, I feel like I've tried pretty much everything.

Worthy note: Since the clean install back then I didn't immediately use my email account with the System knowing that it would create a user folder with the name of my email account, so I made a local account and then later just signed in with my email and associated the system with that. This might be a possible problem seeing as how retarded Microsoft's account and permissions system has been going lately (since Win8).

I would really appreciate if someone guides me through a fix, post your ideas about a fix and I'll try them and report back.
Also no viruses on this PC either, running nod32 v9 activated and have done recent scans with Malwarebytes and nod32 which found nothing.

Disappearing apps and programs

I downloaded the new windows 10.

I had Cortana and windows store. Then they stopped working. Did I press the wrong button somewhere?

I got the error code 0x80070005. I tried all the suggestions etc. Nothing seems to work. Is there some easy remedy to fix this?

 

Windows update Error 0xc1900204

I cant download any updates because of this error. I have followed all the guides all over the internet, i even fixed problems on my computer i didnt know i had. Theres nothing i havnt done.

I did the 3 methods here: windows 10 anniversay update Error 0xc1900204

which didnt work at all

I tried manually update it. Didnt work. I tried resetting windows update. Didnt work. I tried deleting softwaredist, didnt work. Tried deleting cahoot2. didnt work. Downloaded "Tweaking" which should have fixed a lot of problems, but it didnt fix windows
update.

Im at the bottom, theres nothing i havnt tried. I cant reset to factory, because i have lots of things i need on the computer. But people on the internet has tried resetting, and it didnt work for them.

I tried sfc /scannow, which succeeded after i did some things, but still doesnt work. Everything has been tested. but still Error 0xc1900204

I hope you can help me, thanks.

 

Nevermind then as I have fixed the problem myself after numerous failed attempts.
This is what fixed it:
1.Downloaded a program called Windows Repair (v3.9.3 Free Version)

2.After installation run the program as administrator

3.Head over to the Backup tab and backup your Registry and create a System Restore point.

4.Head over to the Repairs tab and click Open Repairs

5.Select options: 1,2(Select Win Drive in my case C,14,28(Completely Reset App Store) and 29.
I didn't select the side options but if you want to you can.

6. Click Start Repairs and wait
I wouldn't recommend interrupting it but I had some problems with the repair getting stuck at running some powershell commands (specifically command number 4). In that case I just closed the CMD window and it would continue with other repairs.

7.After its all done close the program and restart your computer.

8.Run the store and try updating/installing apps and it should work.

This is what fixed the Windows Store for me, every other step I tried achieved absolutely nothing.
I believe it was a permissions problem as the error code means that access was denied.

I hope this post helps someone else.
