What’s new in Windows 10 KB5031445
Microsoft has not added any new features in this release, and the update acts as a bug for Windows 10, resolving nine issues.
The three highlighted fixes and new features in the KB5029331 update are:
- Addresses an issue that affects touchscreens
- Supports daylight saving time (DST) changes in Syria
- This update addresses a memory leak in ctfmon.exe
The only known issue in this update causes BitLocker errors:
“Using the FixedDrivesEncryptionType or SystemDrivesEncryptionType policy settings in the BitLocker configuration service provider (CSP) node in mobile device management (MDM) apps might incorrectly show a 65000 error in the “Require Device Encryption” setting for some devices in your environment,” explains the release notes.
“Affected environments are those with the “Enforce drive encryption type on operating system drives” or “Enforce drive encryption on fixed drives” policies set to enabled and selecting either “full encryption” or ‘used space only’.”
“Microsoft Intune is affected by this issue but third-party MDMs might also pe affected.”
Microsoft says this is only a reporting issue, not a BitLocker drive encryption problem. Redmond says they are working on a fix and will release it when it’s ready.
A complete list of fixes can be found in the KB5031445 support bulletin.
