About one week ago, Microsoft released Update Preview KB4577063 for Windows 10 20H2 users bringing the OS Build to 19042,541. There are quite a few fixes that came with the update, including a fix for the Windows Subsystem For Linux problem that encountered an “Element not found” error message and several other problems.
One week passed, today Microsoft seems to be releasing Update Preview KB4577063 for Windows 10 20H2 users either on Beta Channel or Release Preview, even though the update has the same name (KB4577063), it includes additional fixes including changes to the OS Build which is now 19042,546.
Based on the windows blog page, there are two additional fixes and one of them is a fix for an issue that prevented the device from going into standby mode and a fix for the reliability issue on Microsoft Edge that occurs when users open multiple windows or tabs.
To get this update, for those of you who are Insider Beta or Release Preview users, you can go to Settings> Update & Security> Windows Update, and please click Check For Update and download the available KB4577063 preview update.
