Microsoft admits that Windows 10 KB4571756 caused WSL2 failure and compatibility error warnings
Every time Microsoft releases a cumulative update, it will bring new problems. Recently, Microsoft quickly admitted to the problems caused by the cumulative update this month (KB4571756), perhaps because the WSL2 problem affected too many developers to use it normally.
The installation of this month’s cumulative update will cause a remote call exception to the WSL 2 function, which will also directly cause the Linux subsystem to fail to start normally.
This is a very troublesome problem for developers, because many developers now rely on subsystems for programming, development, debugging, and even operation and maintenance.
After extensive media reports, Microsoft stated in its official blog that there is an abnormality in WSL 2. After tracking by internal experts, the cause of the problem has been determined.
However, it cannot be repaired at present, so if the developer is affected, please uninstall the KB4571756 cumulative update. After uninstalling the cumulative update, the subsystem can start normally.
Microsoft did not explain what caused the abnormality and did not disclose the specific repair timetable, which means that the problem may not be resolved in a short time.
The cumulative update of this month also caused the start menu of some devices to fail to open, that is, it flashed back when clicking the start menu, or there was no response except for icons after clicking.
Some users still experience the blue screen of death after installing the cumulative update, but Microsoft has not acknowledged these problems so it is not clear what the specific reasons are.
Microsoft admitted that Lenovo’s ThinkPad had compatibility issues that caused the blue screen of death, but it is unclear whether the blue screen of death on other non-Lenovo devices is related.
Of course, if there are frequent crashes or the start menu cannot be clicked to affect normal use, it is recommended that users directly uninstall the latest cumulative update and wait for the repair.
In addition to subsystem issues, Microsoft quietly admitted in a document that there was a compatibility error warning for feature updates. Users may see this document if they search.
In this document, Microsoft admits that “When updating to Windows 10, version 1903 or Windows 10, version 1909 from any previous version of Windows 10, you might receive a compatibility report dialog with “What needs your attention” at the top and the error, “Continuing with the installation of Windows will remove some optional features. You may need to add them back in Settings after the installation completes.” You might receive this compatibility warning when LOCAL SYSTEM accounts are blocked in a firewall from accessing the internet via HTTP. This is caused by the Windows 10 Setup Dynamic Update (DU) being unable to download required packages.”
This problem mainly causes users to be unable to upgrade to the latest version of Windows 10. The latest cumulative update has been integrated into the feature update, so it will have some impact.
In response to this problem, Microsoft said it is working on a targeted fix. The company will fix the bug in the upcoming cumulative update to allow users to upgrade to the latest version.
