- Addresses an issue that affects a scheduled monthly task. It might not run on time if the next occurrence happens when daylight savings time occurs.
Addresses an issue that affects all the registry settings under the Policies paths. They might be deleted. This occurs when you do not rename the local temporary user policy file during Group Policy processing.- This update affects the Desktop Window Manager (DWM). It improves its reliability.
- Addresses an issue that affects .msi files. A minor update is not installed. This occurs when you use the EnterpriseDesktopAppManagement configuration service provider (CSP) to distribute the .msi file.

When the permissions are wrong, the Start menu, search, and Azure Active Directory (Azure AD) authentication fail.
