Microsoft is rolling out Windows 10 KB4508433 with at least
three important fixes to improve Windows Update experience.
Windows 10 KB4508433 is supposed to replace the
KB4506933, which is also a servicing stack update.
As Microsoft explains, KB4508433 improves Windows 10’s
servicing stack, which is the OS component responsible for
downloading and installing updates. The update was released on
July 26, 2019, and it will automatically install on some
devices. The same update was released to Release Preview Ring
users earlier this month.
According to the changelog, Windows 10 KB4508433 has resolved
an annoying bug where some Windows 10 updates will require two
reboots and scans to complete the installation when certain
other updates are installed.
Windows 10 May 2019 Update (version 1903) introduced a new
feature called ‘Reserved Storage’ to ensure easy installation
of updates in the future. While it improves the upgrade
experience, it takes up at least 7 GB of your device’s
storage for updates and optional files.
The latest servicing stack update fixes an issue
where reserved disk space won’t release space when the
installation of Language Packs and Features on Demand fails.
The disk space was released only when the user manually
activated Storage Sense’s cleanup and freed up storage.
Another bug causing Windows 10 update installation failures has
been fixed. Microsoft says the issue was experienced when the
user checked for updates during installation or uninstallation
of Windows 10 update, Language Packs, or Features on Demand
A new compatibility update
Microsoft has also released KB4511712 to
improve the installation and recovery experience on Windows 10
version 1903. This update will also download and install
On July 26, Microsoft also shipped a new patch for Windows 10
version 1903 with a long list of improvements.
Windows 10 KB4505903 bumps the OS to Build 18362.267 and
offers a variety of bug fixes and improvements for Edge,
Windows Hello and other features.
The company also fixed issues with important features like the
Start menu. As per the changelog, a new change has been
implemented to ensure that Start works as expected when new
users sign in to the device.
Build 18362.267 also
hides the UWP Microsoft Edge when preview build of
Chromium-based Edge is installed on your PC.
