Windows 10: Windows 11 UWP App : Windows Security *Microsoft.SecHealthUI* reinstallation issue.

I used the O&O App Buster to uninstall/remove unwanted pre-installed UWP apps from my Windows 11.I managed to uninstall the "Windows Security" *Microsoft.SecHealthUI* UWP app in the process.Now, my question is, how do i re-install Windows Security with a powershell command? I tried several things, but so far I had no luck.I now have an inaccessible "Windows Security" and the following entry show up at the bottom of my Start Menu/All apps list : "ms-ressourceisplayName" preceded by the Windows Security iconNone of those powershell admin command worked ISM.exe /Online /Cleanup-imag

Microsoft Adds Ability to Block Win32 Apps from Install on Windows 10

Yes, UWP is an interpreter, an app running in UWP can't function without the interpreter. Only the UWP core has access to the actual hardware, the app does not.

By not having direct access to the hardware, they perform slower. UWP has to translate everything and make sure it passes safety and security checks.

If UWP has issues, all of the apps running on top of it also will. I've seen that in early release of Windows 10 where all UWP based, Windows-included apps broke (Edge, Calculator, Mail, etc.). Granted, it was only broke in one user account.

 

Microsoft Botches Up UEFI Support for Windows 7 on ASUS Motherboards

• It lacks SecureBoot - making it impossible to flesh out a rootkit or something that attacks the boot order. Why this bug even exists in the first place I can't say, but SecureBoot can be used by either Windows or a modern Linux Distro, and Windows 7 doesn't support it.
• To go even further than SecureBoot, if you have a Windows 8.1 or Windows 10 system that utilizes a TPM (1.2 or 2.0, doesn't matter) it uses an even more secured version called Timed Boot. This is what I use on my desktop at home.
  
• There is no HEASLR support, only ASLR, making 64-bit applications inherently less secure in Windows 7 than Windows 10 as they lack a higher entropy randomization.
  
• The WDDM graphics drivers in Windows 10 (WDDM 2.x) are both more performant, and more secure than the WDDM 1.x driver model in Windows 7
• In both Windows 8 and Windows 10 there is a new - and more isolated/secure - Integrity Level available that isn't available in Windows 7. It's even available to be used by Win32 applications, not just UWP apps. IE11 used it before it was replaced by Edge for example. Integrity Levels are what Microsoft refers to as "sandboxing" and Chrome for example runs in a "Low" integrity level. The additional security feature in Windows 8 and Windows 10 is known as "App" level, but don't let the name confuse you. Even a Win32 "desktop" application can utilize it if it wants. It doesn't need to use the UWP framework.
  
• Speaking of UWP framework, it in and of itself provides a great security barrier. I use the Foxit PDF viewer UWP app because literally everything is sandboxed about it. It can't touch the registry, it can't touch the disk where it's not allowed, it can't interact with other applications, it can't auto-elevate itself. This provides some detriment to high-performant applications like games, but that's not what I'm referring to here.
• The additional of Control Flow Guard for applications written in Visual Studio 2015 or above is only available in operating systems more modern than Windows 7.
• The UAC is actually improved, as the AMSI engine scans every program that triggers a UAC elevation prompt for known malware.
• There's also a whole host of Enterprise security improvements that sadly are unavailable to us private users (even with Windows 10 Pro) like Device Guard that adds some really neat security checks that are isolated from the system using Hyper-V to virtualize its existence to prevent malware from abusing it.
