These are applications that can block you from upgrading to Windows 11 24H2 version

24H2 will be the only major system update for Windows 11 in 2024. This update is expected to launch around the end of the year, and is currently available in the Windows Insider program. Naturally, Microsoft wants to make sure the operating system works well on supported hardware and doesn't cause trouble for customers. For that reason, all devices with incompatible software, hardware or drivers will be blocked from switching to the new version.

German-language Windows blog Deskmodder dug into the appraiser.sdb file in build 26100 and discovered that Microsoft has expanded the file with new programs that could theoretically block users from accessing it. Windows 11 version 24H2. This list includes applications like StartAllBack and ExplorerPatcher… which are both applications that Microsoft recently blocked on 24H2 builds. The specific list includes:

1. ConisioAdmin.exe (Solidworks PDM)
2. EaseUS Disk Copy.exe (EaseUS Disk Copy Application)
3. ep_dwm.exe (ExplorerPatcher) Included since 22H2
4. iCloudServices.exe (iCloud files shared in Explorer via WhatsApp) from 23H2
5. RadeonSoftware.exe (AMD GPU perf settings) From 23H2
6. StartAllBackCfg.exe (StartAllBack) Included since 22H2
7. Multi-mon + Copilot (Microsoft)
8. MergeSdb (Microsoft)
9. Intel IntcOED.sys (Intel)
10. Intel IntcAudioBus.sys (Intel) (%WinDir%System32driversIntcAudioBus.sys)
11. Realtek 8192su Wireless USB 2.0 Adapter (Realtek) (%WinDir%System32driversRTL8192su.sys)

It's also worth noting that Microsoft may block specific versions of apps, such as the Windows 7 version of VLC. Therefore, newer versions of these apps could theoretically work fine. on Windows 11 24H2. Normally, Microsoft will inform users about major caveats in its official update notes document.

In addition, there are still a few months until the public release of Windows 11 version 24H2. Therefore, users expect Microsoft to provide many fixes and patches in the near future.

Software blocking is generally not difficult to deal with (you can always update to a newer version or uninstall the problematic app), but it's different. Version 24H2 will be the end point for those running Windows 11 on very old computers running processors without the SSE4.2/4a instruction set (including the POPCNT instruction set).
