the Known Issue Rollback for the update KB5082063

Hello,

The Known Issue Rollback (KIR) mechanism is Microsoft’s official way of mitigating regressions introduced by cumulative updates without requiring full patch removal. For KB5082063, the BitLocker issue is indeed covered by a KIR release. However, KIR does not apply automatically to domain-joined machines unless you explicitly deploy the rollback policy via Group Policy. On unmanaged consumer devices, the rollback is delivered through Windows Update, but in enterprise environments you need to push the KIR GPO so that the affected registry values under HKLM\SOFTWARE\Microsoft\PolicyManager\current\device\Update are set correctly.

If your concern is preventing the BitLocker problem across your domain, then yes, implementing the KIR through a GPO is the correct approach. Microsoft provides the ADMX/ADML templates for each rollback package, and you should import the corresponding KIR policy file into your central store. Once applied, the GPO will enforce the rollback on all targeted machines, effectively disabling the faulty code path introduced by KB5082063. This ensures compliance and avoids having to manually uninstall the update.

The important point is that LTSC or SAC channel doesn’t change the requirement: domain-joined devices will not receive KIR automatically. If you want to be proactive and prevent the BitLocker issue, you should deploy the KIR GPO across the OU containing your workstations. Make sure to test on a pilot group first, confirm that the rollback is applied by checking the event logs under Applications and Services Logs\Microsoft\Windows\Known Issue Rollback\Operational, and then expand to production.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

Yes. For a domain environment, implementing the Known Issue Rollback (KIR) via Group Policy is the supported way to mitigate a regression from a specific nonsecurity update such as KB5082063, including BitLocker‑related issues if Microsoft has published a KIR for that KB.

Key points and steps:

1. Confirm that a KIR exists for KB5082063
   • Check the Windows release notes/update history for the OS version in use and look under Known issues in this update.
   • If Microsoft has published a KIR for the BitLocker issue in KB5082063, the documentation will include a link to a KIR policy definition .msi file for enterprise deployment.
2. Download and install the KIR policy definition
   • Download the KIR .msi that corresponds to the affected Windows version.
   • Run the .msi on the management workstation (or on each device if using Local Group Policy). This installs the KIR Administrative Template into C:\Windows\PolicyDefinitions (or copy the .admx/.adml to the Central Store if used).
3. Deploy KIR via a domain GPO (recommended for domains)
   • In Group Policy Management Console:
     1. Right‑click the domain and select Create a GPO in this domain, and link it here (for example, name it KIR KB5082063 BitLocker).
     2. Edit the GPO and go to: Computer Configuration → Administrative Templates → KB ####### Issue XXX Rollback → Windows 10/11, version YYMM (names depend on the KIR template).
     3. Open the policy and set it to Disabled, then OK. For KIR templates, setting the policy to Disabled activates the rollback.
4. Apply and verify on domain devices
   • Allow normal Group Policy refresh (typically within 90–120 minutes) or force it on a device with gpupdate /force.
   • Ensure each affected device is restarted after the policy is applied. The rollback only takes effect after restart.
   • After restart, the change introduced by KB5082063 that caused the BitLocker issue is reverted, while the rest of the update remains installed.
5. Lifecycle considerations
   • KIRs are temporary and apply only to nonsecurity updates. Once Microsoft releases a fixed update that resolves the BitLocker issue, the KIR becomes benign and can be removed from the Group Policy infrastructure if desired.

If no official KIR is published for KB5082063, Group Policy–based KIR deployment is not available for that issue and other mitigations must be used.
