Change Number of Quick Actions to Show in Windows 10 Action Center

@SM03,

It appears this will no longer work. Any attempts made to make something work just ends with a broken Action Center.

Hopefully something will come along in the future.

Yes, that's why I told you about this after trying, anyway, I'll wait for your solution, let me know if you find any.

I figured out how to expand it programmatically.

ShellExperienceHost.reg:
Windows Registry Editor Version 5.00

[HKEY_USERS\ShellExperienceHost\LocalState]
"isQuickActionCenterViewExpanded"=hex(5f5e10b):01,9a,c0,d7,b7,26,27,d6,01

Sample script: (only tested on a Windows 1909 Pro x64 VM)
taskkill /f /im ShellExperienceHost.exe
reg load HKU\ShellExperienceHost "%LOCALAPPDATA%\Packages\Microsoft.Windows.ShellExperienceHost_cw5n1h2txyewy\Settings\settings.dat"
reg import ShellExperienceHost.reg
reg unload HKU\ShellExperienceHost

Notes:
- The settings are stored in the registry hive located in %LOCALAPPDATA%\Packages\Microsoft.Windows.ShellExperienceHost_cw5n1h2txyewy\Settings
- The value is of type 5f5e10b. I don't think you can set that with reg.exe, so you need to import the reg file.
- The first byte seems to determine if it's expanded (01) or not (00). The rest of the bytes appear to be a timestamp. I just copied it after expanding it manually.
- After you run the script, if you click on the Action Center icon on the taskbar, ShellExperienceHost.exe will start up and it should now be expanded.
- To apply for new users, you probably want to copy the modified settings.dat into the corresponding folder with a RunOnce script. Haven't tested it though.

Is there anything that come out for this? in 20H1 or in any recent build?

I didn't find any reg path like this as you mentioned

HKEY_USERS\ShellExperienceHost\LocalState

can you recheck? And can you share the script for testing? which version of Windows did you use?

You need to load this hive first:
%LOCALAPPDATA%\Packages\Microsoft.Windows.ShellExperienceHost_cw5n1h2txyewy\Settings\settings.dat

To do it manually, open regedit, then highlight HKEY_USERS, File > Load Hive. Then set any name you wish (I chose ShellExperienceHost, hence the path is HKEY_USERS\ShellExperienceHost\LocalState).
Note that you must stop ShellExperienceHost.exe to be able to load the hive.

Hope this helps.
