Windows 10: How to resolve performance issues as a result of Windows 11 24H2?

I have been away from my computer for over a month but it appears my last update prior to leaving was KB5046732 - PC AMD Ryzen 5 7600 worked perfectly fine at this time. Have been using Windows 11 for years without issue. PC updated yesterday to KB5048667 prior to my hearing about all the issues with 24H2 - I recall there being an error popping up initially with the updating, which others have reported, but it eventually pushed through. Since then, I have encountered significant performance issues - no game will open will just blackscreen, closing a game will have it continue in the backg

I'm currently running Windows 11 version 24H2 build 26100.863 and I'm considering performing a factory reset on my device.

Is there anything specific I need to be aware of before performing a reset on this particular build version? Are there any known issues or bugs I should be cautious of?

Any advice on the best way to perform a factory reset on Windows 11 24H2 build 26100.863 would be greatly appreciated.

 

Windows Security Issue: Missing 'windowsdefender' in Windows 11 24H2 (26100.863)

Chewed on this for a day. My first post as well. Hopefully this finds people in the same boat.

Known issue

New Windows 11, version 24H2 devices that are intended to be onboarded to Microsoft Defender for Endpoint might require customers to enable the prerequisite feature. This affects all supported architectures.

IT admins might observe devices not being able to be onboarded to the Defender for Endpoint cloud service, and not receiving the expected protection as a result, even if Intune is expected to execute the onboarding sequence by applying an endpoint detection and response (EDR) policy. Intune will also display an error as it is unable to successfully apply the policy. Users may also not be able to connect to corporate resources if a Conditional Access policy is configured to require Defender for Endpoint being enabled and actively reporting in. Compliance status is visible in the Microsoft Intune device compliance dashboard. This might happen in one of the following scenarios.

• A user buys a new device that has the Home SKU. This SKU does not support Defender for Endpoint. Then the user upgrades to Pro using a Pro product key. This process, called “transmog,” does not install Defender for Endpoint, which is by design. The Defender for Endpoint agent is not correctly enrolled in the Defender for Endpoint service, and the device is not protected.
  
• A user buys a new device that has the Pro SKU, and the OEM did not install the required feature.
  

Important Defender for Endpoint has been removed from the base image for Windows 11, version 24H2 and needs to be manually installed whenever a device goes from Home to Pro.

Workaround

Use the Deployment Image Servicing and Management (DISM) command-line tool to install the Windows Sense Client from an elevated command prompt. See the command below.
