Windows users who rely on the Alt + Tab shortcut to quickly switch between open applications have run into a frustrating bug with the recent Windows 11 24H2 update. This feature, which is essential for multitasking, currently triggers a black screen delay of up to 10 seconds. Although the shortcut itself isn’t completely broken, this unexpected pause can be disruptive for anyone needing to switch apps in real time.
Widespread User Frustration Over the Black Screen Bug
After installing the Windows 11 24H2 update, many users began reporting this black screen glitch across forums and community posts, including popular sites like Reddit. For most, the issue appeared shortly after upgrading to 24H2, with users discovering that the problem persisted even on different systems. For anyone affected, one way to revert to the previous Windows version is by rolling back the update—but this option is only available for 10 days after installation, leaving a limited window for those who want to avoid the bug entirely.
Microsoft’s Response and Available Fixes
Microsoft acknowledged the black screen issue with Alt + Tab and rolled out a preliminary fix in the optional October 2024 update. However, optional updates don’t install automatically, so users must manually download this patch. Even then, the fix may not take effect right away due to Microsoft’s phased rollout approach. The company has also assured users that a full solution will be included in the upcoming December update, which should gradually resolve the bug for everyone with Windows 11 24H2.
Temporary Workarounds for the Alt + Tab Black Screen Issue
In the meantime, there are a few potential workarounds that may alleviate the problem:
Disable Game Mode: Microsoft’s Game Mode feature appears to contribute to the issue. Turning it off can reduce the black screen duration, though it doesn’t eliminate it entirely.
Disable Hardware Acceleration: For those encountering the black screen within browsers or social apps like Discord, disabling hardware acceleration might help. Unfortunately, this setting isn’t available in every app.
Turn Off Windowed Games Optimization: Another workaround involves disabling the “Optimizations for windowed games” feature, which aims to reduce latency when switching apps. You can do this by going to System > Display > Graphics > Optimizations for windowed games and toggling off the option.
While these fixes are not foolproof, they may help reduce the length of the black screen delay until a permanent solution arrives.
Looking Ahead: Official Fixes and Other Bugs in Windows 11 24H2
A comprehensive fix for the black screen issue with Alt + Tab is expected in the November Patch Tuesday update for Windows 11 24H2. However, users should be prepared for a gradual rollout, as Microsoft often releases updates incrementally to monitor performance and stability.
Beyond the Alt + Tab bug, Windows 11 24H2 has a few other known issues. Some users have reported that the File Explorer menu appears outside the visible screen area, while others experience disruptions in network connectivity, including Wi-Fi failures and network sharing errors. While these issues may not impact all users, they serve as a reminder to approach new updates with caution, especially on mission-critical devices.
Final Thoughts
While Microsoft has made significant improvements with Windows 11, this black screen glitch with Alt + Tab in the 24H2 update highlights the importance of timely updates and community feedback. Users experiencing this issue should stay informed about the upcoming December patch, which promises to fully address the black screen delay. For now, the temporary fixes outlined above may offer some relief for those affected.
