IMPORTANT We have been evaluating the public health situation, and we understand this is impacting our customers. In response to these challenges, we are prioritizing our focus on security updates. Starting in May 2020, we are pausing all optional non-security releases (C and D updates) for all the supported versions of Windows client and server products (Windows 10, version 2004 down to Windows Server 2008 SP2).
There is no change to the monthly security updates (B release – Update Tuesday); these will continue as planned to ensure business continuity and to keep our customers protected and productive.
- Updates an issue that might prevent certain printers from printing, generate print errors, or cause apps and print spoolers to close unexpectedly.
Improvements and fixes
This non-security update includes quality improvements. Key changes include:
- Addresses an issue that might prevent certain printers from printing. The print spooler might generate an error or close unexpectedly when attempting to print, and no output will come from the affected printer. You might also encounter issues with the apps you are attempting to print from, such as receiving an error, or the app might close unexpectedly. This issue might also affect software-based printers, such as when printing to PDF.
If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.
Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.
