That Ulitimate Performance is great and even worked on 1703/1709 and gets the ultimate lable when Build upgraded

but

Lenovo like many other manufactures pre-building PC's now have there own Power Plans created and must be used in order for the machines to matchup correctly ...

Lenovo I know is big on having all drivers available, also both Dell and HP to have created Huge Default Win10 setting packages that are Build Labeled that correct and install proper power plans and system config file tables to boot / login correctly. Talking big, between 300mb-500mb of nothing but Win10 manufacture cofig files, also explains why a lot of registry entries are now empty, good if clean installing settings, bad for everyone else that is left without manufacture support.

Amazing how well a Win10 PC runs after a package like that is installed, most would think those problems were driver related turns out was just the PC setup was wrong.

Not sure how many wil follow this info, but is true and gets known soon as someone runs into a 2016 or newer Win10 PC

I have solution for you then, if your wanting to defer 1803 and stay on any (build) that's 1709 and below

Click your Start Button, type:  services  :and hit Enter

Scroll down to find Windows Update Service

If it is Started, double click it and stop that service

Close the services App

Click your Start Button, type cmd, right click Command Prompt and choose 'Run as Administrator'

Run this command and hit Enter

sc delete wuauserv

Close Command Prompt

Restart your PC

Enjoy Win10 on any build you like until end of life of device

Hope this helps, if it did and this is final answer don't forget to close thread

Quick question, did you Disable Secure Boot ,... but stayed in UEFI boot mode,.. , to allow Windows10 to install the drivers ? If you go Legacy it will fail/crash

If you stay secured, it will fail / crash and bcedit ,cmd.exe, the entire %sys% folder.. just about everything WILL stay locked and revert any changes upon next reboot.

Thought i would ask,no one has mentioned it. Even the WMI stays locked from acces unless its the Store for the new rules of 1803

Hiya, after thinking about it some more, i have a Relive system on 1803 and tried something that worked, rather than upgrading to the newer drivers for what ever reason, what you gotta do is

Open File Location Radeon from start menu, follow that puppy until you hit the folder its in.

Tick box the Radeon Settings --  file Properties  / Compatibility Tab Like seen in pic Also Use the new DPI settings for app

Click APPLY and Close , oprn Radeon , Click YES, UnTick Taskbar Icon, close it, or look at your setting, (You cant use the Tray icon option this way, it will never appear )

Now Reboot. Everytime Radeon needs something you should now see your Admin box appear or when settings is opened, such as to run a game.

You shouldn't be bothered anymore by Radeon Settings unless it really needs to do something or is opened and now Radeon's config's will save and stay saved.

Hope this helps,

Edit:: To add in last part

If your worried about Radeon not running during your games or normal use, just open Radeon Settings Click Yes everytime, and it will stay running in the Task Manager saving and configuring without reverting back to crash/fail

This is probably one reason new drivers are created, Win10 1803 overhauled the security, so this trick always will work. Little bit of a pain over getting the newer set of drivers, but stable.

Ah, no problem. I'm always hanging around the web on one system or another. What would i do if i didn't have Windows-10 to look at

Manufactures are replacing boards all time, no biggie. It could be worse.  Still, there might be a few progs in the Store or the sys32 folder you might want to grant permissions to or

Easy way around a lot of trouble. Send / Save all your installers to your desktop . It might sound crazy but those permissions are locked to (unlock) so anything on your desktop wont suffer resistants.

When you get a chance again, just Right+Click your Desktop icon in the file explore, cright click its propertis and Tab Security for it and you will see only 3 main granted full permissions.

Those are what yoyr going to compare to when granting Full access to anything , just those three. They are System, Admin Desktop(name of desktop). and

your username User(desktop)

The desktop icon found in Quick Access will work to just have a look, but if anything starts to run funny, you will know what security to look for. If it doesn't match the desktop icon properties, you'll know what to do. Not everything, but a lot is supposed to look like that .... MS dropped the ball on that long time ago.
