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. |
