Microsoft has begun rolling out Windows 11 version 25H2, the fall feature update. As the rollout continues, Windows Latest reports four known bugs that Microsoft is aware of. The issues could affect playback of DRM protected media, file sharing via SMB v1, the Media Creation Tool on ARM devices, and installation of updates through the Windows Update Standalone Installer (WUSA).
Four known bugs in Windows 11 25H2
DRM protected media playback
One of the first reported issues concerns DRM protected files. Some video and audio files protected by digital rights management may fail to play or stutter in certain apps after upgrading to 25H2. The impact varies by content vendor and app. At the moment Microsoft has not posted a universal fix, so users who rely on DRM content should monitor updates and consider delaying upgrading on critical machines where uninterrupted media playback is essential. Workarounds include using non DRM content where possible and keeping apps up to date to mitigate compatibility problems.
SMB v1 file sharing
A second bug affects file sharing over SMB v1. In some networks the ability to share files or access shared folders may be unreliable after the upgrade. Given the security risk associated with SMB v1, many organizations already disable it, but some home networks rely on older setups. If you must share via SMB v1, plan for changes or prepare to migrate to newer SMB protocols; as a temporary measure, you may need to avoid 25H2 on devices that depend on SMB v1 sharing until a patch is released.
ARM based devices and the Media Creation Tool
A third issue concerns ARM based PCs. The Media Creation Tool may not run correctly on ARM devices, making it harder to create installation media or upgrade manually. Users with ARM hardware should consider alternative installation methods, such as downloading a Windows 11 ISO from official sources or using other supported upgrade paths. Microsoft has not yet provided a universal fix for ARM devices, so upgrading strategy may need to be adjusted on affected machines.
Windows Update Standalone Installer problems
The fourth bug involves update installation via WUSA. Some cumulative updates may fail to install when using the standalone installer, leading to confusion and frustration. The recommended approach is to rely on the standard Windows Update mechanism for now and postpone WUSA only if you can. If you encounter WUSA errors, run the built in troubleshooter, check system integrity, and defer non essential updates until a patch is available.
Should you upgrade now or wait
With four known bugs acknowledged by Microsoft, cautious users may want to wait before installing 25H2 on production machines. If your setup relies on DRM content, SMB v1 networks, ARM upgrade workflows, or regular standalone updates, delaying the upgrade while Microsoft ships fixes can save time and trouble. For many users the fall update will bring valuable improvements, but a staged approach or testing on a non critical PC is wise while patches are prepared.
Practical steps if you decide to upgrade
If you choose to proceed, back up important data, create a system restore point, and ensure you have a working rollback plan. Keep monitoring official channels and independent outlets for confirmation of fixes. After upgrading, install all pending updates and avoid uninstalling essential security features. In the meantime, check Windows Latest for the latest guidance and bug status updates.
