This update addresses an issue that affects lsass.exe. It leaks memory. This occurs during a Local Security Authority (Domain Policy) Remote Protocol (LSARPC) call.
Starting in this update, File Explorer adds the Mark of the Web (MoTW) tag to files and folders that come from untrusted locations.

This might affect some scenarios that rely on file copy operations.

Those of you who use the Home edition of Windows are not likely to experience this issue. MCC and DHCP Option 235 are typically used in enterprise environments.	This issue is addressed in KB5040525.
