Important
An upcoming change to Windows, included in the April 2026 Windows Server update, the default Kerberos encryption type is changing from RC4 to AES-SHA1.
File shares hosting FSLogix containers that aren't upgraded to AES-SHA1 might have access issues after this change is applied. To avoid disruption, complete the upgrade to AES-SHA1 before installing the update.
Customers who have already upgraded to AES-SHA1 aren't affected.
For more information, see the FSLogix blog: Action required: Windows Kerberos hardening (RC4) may affect FSLogix profiles on SMB storage.
Reboot required after install
FSLogix installs Windows services and file system (minifilter) drivers. These components require the virtual machine to be restarted.
