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.
Known issues in this update
Symptom |
Workaround |
After installing this update, the Encrypted File System (EFS) API OpenEncryptedFileRaw(A/W), often used in backup software, will not work when you back up to or from a Windows Server 2008 SP2 device. OpenEncryptedFileRaw will continue to work on all other versions of Windows (local and remote). |
This behavior is expected because we addressed the issue in CVE-2021-36942. Note If you cannot use backup software on Windows 7 SP1 and Server 2008 R2 SP1 or later after installing this update, contact the manufacturer of your backup software for updates and support. |
