Issues with Windows 11 KB5070311: Installation Failures, Dark Mode Problems, Missing Login Password Icon, and Intel Arc Driver Bugs

Released a bit behind schedule, Windows 11 KB5070311 marks November 2025’s optional update. While it brings a range of quality-of-life enhancements, some significant issues have surfaced. Notably, users might encounter installation failures characterized by errors such as 0x80070306. Furthermore, if the update is successful, it may disrupt dark mode functionality in File Explorer and lead to complications with Intel Arc GPU drivers.

One user expressed their frustration, stating, “The new update for 2025-11 Pre-Update Update KB5070311 (26200.7309) is giving ERROR 0X80070306. I usually update everything, but I don’t know why it’s giving an error. I have already paused and enabled updates, but it keeps happening. Does anyone else have the same problem, or will Windows release a new update to fix it?”

It’s worth noting that issues with Windows updates are not uncommon. Therefore, if you experience complications while attempting to install Windows 11 KB5070311, it may be best to bypass this release altogether. Since it’s categorized as an optional update and labeled “preview, ” it is expected to contain bugs, even though it doesn’t fall under the Insider technical preview build classification.

Microsoft Acknowledges Dark Mode Issues

Following the installation of Windows 11 KB5070311, many users have reported experiencing flashes of white when interacting with File Explorer, especially when opening new tabs. However, reports suggest that the problem is more extensive than Microsoft has indicated, with flashes occurring when navigating between various sections of File Explorer, particularly when returning to the Home page.

For instance, if you are in the Program Files folder and click on the Details panel, a white flash will occur. Similar flashes can be observed when switching between the Home, Gallery, and other pages in File Explorer.

While this may not be life-altering for those not using dark mode in Windows 11, it can certainly be frustrating, and users are advised to postpone the update until a resolution is provided.

Invisibility of the Password Icon on Windows Lock Screen

For those utilizing Windows Hello, a new issue has emerged: the password icon disappears when selecting the “Sign-in with other options” button, which appears when a Windows PIN is set as the default sign-in method. This feature includes alternatives such as fingerprint, camera (iris), and standard password login.

Post-update, the password option becomes hidden, affecting all users, including those with local accounts. Fortunately, the password icon is not malfunctioning; it’s merely obscured. Users can still click around the area where the icon should be to access the password entry field.

As Microsoft noted, “If you hover over the space where the icon should appear, you’ll see that the password button is still available. Select this placeholder to open the password text box and enter your password. After entering your password, you can sign in normally.” While this issue may not seem like a significant problem, it could hinder access for those who forget their Windows PIN, especially if they lack alternatives like fingerprint or camera sign-ins.

Currently, Microsoft is investigating this issue, which appears to affect Windows 11 KB5070311 and previous updates, with patches anticipated in the December 2025 Patch Tuesday rollout.

Problems with Intel Arc GPU Following KB5070311

A thread on Reddit highlighted further complications, particularly regarding the compatibility of Windows 11 KB5070311 with Intel Arc B580 GPUs. Users reported serious issues, including blue screens that prevent access to the desktop after the installation of the latest Arc driver. Others have experienced black screens with only a mouse cursor visible.

In some instances, users noticed a warning icon in Device Manager for the Arc B580, and many reported being unable to run most games unless reverting to the earlier 6252 driver that Windows automatically installs.

If you encounter these problems, it is advisable to uninstall the update once you can access the desktop. However, if you face error 0x800F0825 while attempting to remove the update, a temporary solution is to disable Windows Sandbox and reboot your computer, which has proved effective for numerous users.
