Microsoft Removes Upgrade Blocks, Expanding Windows 11 25H2 Availability for Additional PCs

Windows 11 25H2 has officially launched, but many users may find it inaccessible due to existing safeguard holds stemming from compatibility concerns. Recently, Microsoft lifted restrictions that had particularly affected certain Intel PCs, allowing broader access to this year’s feature update.

These upgrade restrictions were initially meant for Windows 11 24H2 but similarly apply to 25H2, as both versions share the same core code. Essentially, the transition to 25H2 is facilitated through a minor “enablement package”for devices currently running on 24H2, which simply updates the version and build numbers.

Devices still operating on versions 23H2 or Windows 10 that were blocked from upgrading to the 24H2 update due to driver or application issues are similarly barred from accessing the 25H2 version.

According to Windows Latest, Microsoft had imposed compatibility restrictions on certain hardware configurations, particularly on PCs utilizing Intel’s Smart Sound Technology and specific integrated webcams. Thankfully, updated documentation from Microsoft confirms that the issues causing these blocks have now been resolved.

Overview of Upgrade Blocks Imposed in 2024

While Windows updates are expected to fix bugs, the recent situations surrounding the upgrade blocks are noteworthy. These issues were first reported nearly a year ago in September 2024.

As stated earlier, since Windows 11 25H2 is essentially an extension of 24H2, unblocking these upgrades significantly increases access for users upgrading to the latest version.

Intel’s IntcAudioBus Issue Causes Upgrade Blocks

In 2024, Microsoft discovered that users with Intel’s 11th-generation processors and newer, utilizing Smart Sound Technology, experienced critical system errors or Blue Screens of Death (BSOD) after transitioning to the 24H2 update. Consequently, an upgrade block was placed on systems running the ‘IntcAudioBus.ss’ file versions 10.29.0.5152 or 10.30.0.5152.

Microsoft indicated that once a suitable fix is available for Windows 11, this block could be circumvented, or users could manually procure an updated driver from their manufacturer’s website. Fortunately, it seems the issues have finally been addressed in Windows 11, and users can now expect to see the 25H2 update appear.

Camera Issues No Longer Preventing Upgrade to Windows 11 25H2

A separate bug affecting webcams also triggered an upgrade block on Windows 11 installations. Microsoft did not communicate the specific impacted devices, leaving many users uncertain about their eligibility for the upgrades to 24H2 and 25H2. Now, however, that barrier has been removed.

This block was entirely reasonable, as many rely heavily on camera functionality for various tasks such as video calls, photography, and Windows Hello authentication, which all became dysfunctional for affected users.

Considering the extensive use of webcams in laptops and PCs, the impact of these restrictions was significant. While individual experiences varied—some users managed to upgrade their personal and work devices without issue—these blocks undoubtedly hindered others.

With the removal of these upgrade barriers, users on Windows 10 or 23H2 devices can now proceed to update to Windows 11 25H2, assuming it’s available within their region. For those eager to upgrade immediately, a guide on accessing Windows 11 version 25H2 using the Installation Assistant or Media Creation Tool is available.

The earlier installation block via the Installation Assistant has now been lifted, allowing users to upgrade seamlessly.

Install Windows 11 24H2 using Installation Assistant

Boxed by the challenges of its predecessor, Windows 11 24H2, users are hopeful that the transition to 25H2 will prove to be smoother. Currently, Microsoft acknowledges a handful of issues associated with Windows 11 25H2. However, these do not appear to pose significant problems for the majority of users.

One specific concern includes a bug that could potentially block SMBv1 file sharing—although this is less likely to impact most enterprises that have transitioned to newer SMB protocols. Additionally, there are reports of the Media Creation Tool malfunctioning on ARM PCs; yet again, this might not be a significant hurdle, given the limited use of this tool by those operating on Snapdragon-based machines.
