Windows 10: Windows 10 Hardening and management

We have about 10 Windows 10 Single user license computers & laptops and would like to harden them and be able to manage them somehow. They're all using Microsoft accounts and are all "Administrators", how do I change them to regular accounts then have an administrator account so that I can limit the accounts from

Windows 10 Pro Update Error after hardening

Hi,

I have a new installation of Windows 10 Pro and after a few days of use, I am getting this error on Windows Update:

"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070426)"

The background is as follows:

I have a new Dell XPS 13 laptop. It came with Windows 10 Home, and I upgraded it to Windows 10 Pro because I need to use it for business and need the extra encryption and other features that Home does not provide. I have implemented security hardening on
the Windows 10 Pro installation following the process documented here: Harden Windows 10 for Security. How to secure Windows 10.

After completion of the hardening steps (first time round), the above error appeared. I assumed that it was due to my hardening steps, so I tried all sorts of fixes and tweaks to repair it, until I finally restored back to a previous restore point from 2
days earlier. After the restore, the windows updates were functioning. I then repeated the hardening steps, while testing Windows Update after each major step in the process. Windows Update continued to work fine through the hardening and even worked fine
after I completed the hardening (the second time). This was yesterday evening when I ended work for the day. Now, this morning (the next day), when I started up my Windows 10 Pro, it is giving the above error once again under Windows Update.

I am not sure whether this is an issue caused by the hardening, or just a temporary issue that will resolve itself. Can somebody please assist and shed some light on the situation.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Hardening Guide

I looked around a bit, and cannot seem to find any guide to harden Windows 10. All I'm looking for is a generic Microsoft hardening guide, I'm really just assuming that one exists at this point. Any help would be appreciated, and thank you in advance.
