Samsung Easy Settings
I have the Samsung Series 9 (NP900X4AC) laptop. Samsung created a stupid little application called Easy Settings to "help" with a number of basic settings. The one useful thing it does is control the special 'FN' key to allow you to use the function key shortcuts. You can live without these keys. And there is probably a way to enable these features without the Easy Settings application.
Samsung never updated this application for Windows 10. As a result you cannot upgrade from Windows 7 to Windows 10 without first uninstalling this application. After you upgrade it won't install with the default settings either. But there are workarounds. Samsung Easy Settings also prevented me from updating to the MS Windows Fall Creators Update. And I suspect it will be an issue in future major updates to Windows 10. Here is one way to get around this problem.
Uninstall Samsung Easy Settings
These directions assume you are running your computer as a standard user and not an Administrative user. When I first upgraded to Windows 10 I had to uninstall another Samsung application as well. But I never installed that again and I don't remember what it was. Follow the directions below to uninstall Easy Settings.
Launch command line and run it as an administrator. Click on the start button and then type 'cmd'. Once you see the command prompt application right click on it and select 'Run as administrator'. Then type the following command.
Scroll down and select 'Easy Settings' and click 'Uninstall'. Reboot to be safe.
Upgrade Windows 10
Once you uninstall Samsung Easy Settings it should be straightforward to upgrade Windows 10 using the Windows tools. Once you are done with the upgrade you can reinstall Samsung Easy Settings.
Install Easy Settings on Windows 10
Download version 188.8.131.52 of Samsung Easy Settings. I got this from the Samsung support site. The sha256sum is shown below.
You can use Windows Powershell to check the sha256sum. In the example below I placed 'Samsung_Easy_Settings.tar.gz' in my 'Downloads' directory. The variable '$ENV:USERPROFILE' equates to 'C:\Users\<your_user_name>'. Adjust the path as required.
PS C:\Users\zaphod> Get-FileHash $env:USERPROFILE\Downloads\Samsung_Easy_Settings.tar.gz -Algo sha256 |FL
Algorithm : SHA256

Path : C:\Users\zaphod\Downloads\Samsung_Easy_Settings.tar.gz
Use 7-zip or another program to unzip and un-tar it to any directory of your choice.
The setup.exe file has already been renamed to setup1.exe. If you download Easy Settings from Samsung directly you must rename setup.exe to setup1.exe.
Right click on setup1.exe and select "Run as administrator". Follow the prompts to install the application and reboot.
Setup Windows 7 Compatibility
You must enable Windows 7 compatibility on Samsung Easy Settings. I am modifying the EXE itself. But you can also do this using the desktop shortcut for Easy Settings.
Navigate to "C:\Program Files (x86)\Samsung\Easy Settings" in File Explorer. Right click on "ControlCenter.exe" and select "Properties". The following window will open. Please note that I have already changed the compatibility to Windows 7. The values are greyed out. You need to click on "Change settings for all users" and provide the Administrator password.
As stated above click on "Change settings for all users". The following screen will appear. Under 'Compatibility mode' check the box for 'Run this program in compatibility mode for:' and then in the drop down list select 'Windows 7'. I also check the box for 'Run this program as an administrator' at the bottom of the screen. See the screen shot below. The two changes are highlighted by a red box. Click OK. And then click "OK" again on the previous screen. Reboot to be safe.
You should now be able to run Easy Settings. And the function keys should operate correctly. Make sure you check the Easy Settings and change things as you wish. It will default back to the Samsung defaults.
The Registry Values
You can also manually edit the registry if you so desire. The changed values are shown below.

Double Check Your Power Settings
The power management settings may change back to the default settings. This will happen if you modified the default settings but did not create a new power plan. One way to check your values is shown below.
From a command prompt run the following command.
C:> control powercfg.cpl
Make any desired changes. Keep in mind some other settings may have reverted back to the defaults. You may need to change a few other items.
