Windows 10: Windows Update Won't Work

So recently I wanted to download updates for my laptop, because last time I updated was last year. I am running Windows 10 Anniversary Update, and I don't have any antivirus. So I just downloaded Malwarebytes and Avast, because Windows Defender Definition update was stuck at 5% Then, when I installed it I get this: Updates are available. Downloading updates 0%. I ran windows update troubleshooter, and it gave me this error: Potential Windows Update Database error detected. It did't fix it, but everything else is good. It wanted to do some updates stuff when checking for updates, but when I select that, it doesn't do anything. I tried deleting SoftwareDistribution folder, but I can't do it, because Windows Update Service won't stop. I tried using Command Prompt in Admin mode to disable the services, but it still didn't work. What do I do?

WIndows Defender Update Error - 0x80240022

I am having the same problem -- windows defender won't update -- through windows update or through defender itself. As well -- the newest windows 10 update won't work either.

 

numbers won't work after windows 10 latest update...

numbers won't work after windows 10 update...They work on google, note pad, word pad, but won't work on AOL, and other websites...

 

So I just tried using the windows update troubleshooter again after posting, and it started suddenly working. Even the database error got fixed, and now, windows update shows me failed updates and other stuff.
EDIT: It broke again. It just stopped working. It is stuck at 9% at downloading KB4015438. What do I do?

 

Start fresh with a clean install of version 1703 (Creator's Update)?
