Windows Installer is very slow on Windows 11 24H2
I am experiencing a recurring issue after upgrading to the latest version of Windows. The problem arises when I try to install any MSI packages. There is a consistent delay of exactly 2 minutes during the "Software Restriction Policy" verification phase of the installation process:
MSI (c) (08:DC) [07:08:23:080]: SOFTWARE RESTRICTION POLICY: Verifying package --> 'D:\Downloads\MuseScore-Studio-4.4.4.243461245-x86_64.msi' against software restriction policy
MSI (c) (08:DC) [07:10:23:757]: SOFTWARE RESTRICTION POLICY: D:\Downloads\MuseScore-Studio-4.4.4.243461245-x86_64.msi has a digital signature
MSI (c) (08:DC) [07:10:23:758]: SOFTWARE RESTRICTION POLICY: D:\Downloads\MuseScore-Studio-4.4.4.243461245-x86_64.msi is permitted to run at the 'unrestricted' authorization level.This issue only started happening after I upgraded to 24H2, and it affects both of my laptops, which are of the same model, but not virtual machines. In the virtual environment, the installation proceeds without any delay, which suggests that the problem may be related to the physical hardware (or driver?) or a specific system configuration. Interestingly, with Windows Server 2025 (which is also 24H2), the issue disappeared completely, and installations proceed without any delay—just like in the virtual machine environment.
OS Version: Windows 11 10.0.26100.3194

I had this same issue on my laptop, I don't know if you used a program such as defender control to disable windows defender (like I did), But I learned that if you have windows defender disabled and still have 'Smart App Control' running in the Windows Security center, it causes that delay. To fix, simply look up 'Smart App Control' in your start menu, and toggle it to off. Hope this helps, this issue was driving me crazy because I couldn't find any solutions, and was trying to install Visual Studio, which has like 500 MSI installers in a row.
