Bug fixes

The following items have been fixed in this release.

  • Fixed issue where the FSLogix Profile Service would crash if it was unable to communicate with the FSLogix Cloud Cache Service.
  • The OfficeFileCache folder located at %LOCALAPPDATA%\Microsoft\Office\16.0\OfficeFileCache is now machine specific and encrypted so we exclude it from FSLogix containers. Office files located outside this folder are not impacted by this update.
  • Windows Server 2019 version 1809, and newer versions of Windows Server, natively support per-user search indexes and we recommend you leverage that native search index capability. FSLogix Search Indexing is no longer available on those versions of Windows Server.
  • Windows 10 Enterprise Multi-session and Windows 11 Enterprise Multi-session natively support per-user search indexes and FSLogix Search Indexing is no longer available on those operating systems.
  • FSLogix now correctly handles cases where the Windows Profile Service refCount registry value is set to an unexpected value.
  • Over 30 accessibility related updates have been made to the FSLogix installer and App Rules Editor.
  • A Windows event now records when a machine locks a container disk with a message that looks like “This machine ‘[HOSTNAME]’ is using [USERNAME]’s (SID=[USER SID]) profile disk. VHD(x): [FILENAME].”
  • Resolved an issue where the DeleteLocalProfileWhenVHDShouldApply registry setting was ignored in some cases.
  • Fixed an issue where active user session settings where not retained if the FSLogix service was restarted. This was causing some logoffs to fail.
  • Fixed an issue where FSLogix did not properly handle logoff events if Profile or ODFC containers were disabled during the session or per-user/per-group filters were applied mid-session that excluded the user from the feature. Now FSLogix logoff related events will always occur based off the FSLogix settings applied at login.
  • FSLogix will no longer attempt to reattach a container disk when the user session is locked.
  • Fixed an issue that caused the FSLogix service to crash when reattaching container disks.
  • Fixed a Cloud Cache issue that caused IO failures if the session host’s storage block size was smaller than a cloud provider’s block size. For optimal performance, we recommend the session host disk hosting the CCD proxy directory has a physical block size greater than or equal to the CCD storage provider with the largest block size.
  • Fixed a Cloud Cache issue where a timed out read request (network outage, storage outage, etc.) was not handled properly and would eventually fail.
  • Reduced the chance for a Cloud Cache container disk corruption if a provider is experiencing connection issues.
  • Resolved an issue where temporary rule files were not deleted if rule compilation failed.
  • Previously, the Application masking folder was only created for the user who ran the installer. With this update, the rules folder is created when the Rules editor is launched.
  • Resolved an interoperability issue with large OneDrive file downloads that was causing some operations to fail.
  • Fixed an issue where per-user and per-group settings did not apply if the Profile or ODFC container was not enabled for all users.
  • Resolved an issue where the Office container session configuration was not cleaned up if a profile fails to load.
  • Fixed an issue where HKCU App Masking rules leveraging wildcards would fail to apply.
  • Fixed an issue that caused some sessions configured with an ODFC container to fail to login.
  • Resolved an issue where the App Rules editor would crash if no assignments were configured.

For the long-standing issue with FsLogix _local user profiles not being properly deleted at logoff, you will need to first test this new FsLogix version in a lab environment and determine if the issue persists or not.
