April 14, 2026—KB5082200 (OS Builds 19045.7184 and 19044.7184)

[Sign-In] Fixed: After you install the Windows update released on or after March 10, 2026, some users might experience an issue signing in to apps with a Microsoft account. Even when the device has a working Internet connection, a “no Internet” error appears during sign in and prevents access to Microsoft services and apps such as Microsoft Teams.

[Remote Desktop] This update improves protection against phishing attacks that use Remote Desktop (.rdp) files. When you open an .rdp file, Remote Desktop shows all requested connection settings before it connects, with each setting turned off by default. A one-time security warning also appears the first time you open an .rdp file on a device. For more information, see Understanding security warnings when opening Remote Desktop (RDP) files.

[Secure Boot]

• This update enables dynamic status reporting for Secure Boot states in the Windows Security App (Settings > Update & Security > Windows Security). Learn more about the status alerts via badges and notifications. Note that these enhancements are disabled by default on commercial devices and servers.
• This update fixes an issue that could cause a device to enter BitLocker Recovery after Secure Boot updates.
• With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.

[Vulnerable driver blocklist] This update introduces a security hardening change that adds known vulnerable kernel drivers to the Microsoft vulnerable driver blocklist. Backup applications that rely on blocked drivers might experience failures when attempting to mount or manage disk images.
These apps relying on blocked drivers might display error messages, including "The backup has failed because Microsoft VSS has timed out during the snapshot creation" or VSS_E_BAD_STATE. Affected users should update to a newer version of their application that uses newer drivers that include the required protections. For more information, see April 2026 Windows security updates introduce protections to known vulnerable kernel drivers.

Devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key
Symptoms

Some devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key on the first restart after installing this update.

This issue only affects a limited number of systems in which ALL the following conditions are true. These conditions are unlikely to be found on personal devices not managed by IT departments.

1. BitLocker is enabled on the OS drive.
2. The Group Policy "Configure TPM platform validation profile for native UEFI firmware configurations" is configured, and PCR7 is included in the validation profile (or the equivalent registry key is set manually).
3. System Information (msinfo32.exe) reports Secure Boot State PCR7 Binding as "Not Possible".
4. The Windows UEFI CA 2023 certificate is present in the device’s Secure Boot Signature Database (DB), making the device eligible for the 2023‑signed Windows Boot Manager to be made the default.
5. The device is not already running the 2023-signed Windows Boot Manager.

In this scenario, the BitLocker recovery key only needs to be entered once -- subsequent restarts will not trigger a BitLocker recovery screen, as long as the group policy configuration remains unchanged. For help finding your BitLocker recovery key, see the article, Find your BitLocker recovery key.

Enterprises are recommended to audit their BitLocker group policies for explicit PCR7 inclusion and check msinfo32.exe for their PCR7 binding status before installing this update.

Resolution

We are working on a resolution and will provide more information when it is available.

To temporarily work around this issue, remove the Group Policy configuration before installing the update (Recommended)

1. Open Group Policy Editor (gpedit.msc) or your Group Policy Management Console.
2. Navigate to: Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.
3. Set "Configure TPM platform validation profile for native UEFI firmware configurations" to "Not Configured".
4. Run the following command on affected devices to propagate the policy change: gpupdate /force
5. Run the following command to suspend BitLocker (where BitLocker is enabled on the C: drive): manage-bde -protectors -disable C:
6. Run the following command to resume BitLocker (where BitLocker is enabled on the C: drive): manage-bde -protectors -enable C:
7. This updates the BitLocker bindings to use the Windows-selected default PCR profile.

Remote Desktop security warnings might not display correctly

Symptoms
After installing this update, the security warning that appears when opening Remote Desktop (RDP) files might not display correctly in some cases.
This issue might occur when you use more than one monitor with different display scaling settings (for example, one display set to 100% and another set to 125%). When this happens, the warning window might show overlapping text or partially hidden buttons, which can make the message difficult to read or interact with.
Resolution
This issue is resolved in Windows updates released on and after May 12, 2026 (such as KB5087544). We recommend you install the latest Windows update for your device as it contains important improvements and issue resolutions, including this one.

[Licensing] Improved: This update addresses an issue that affects Long-Term Servicing Channel (LTSC) image creation using Deployment Image Servicing and Management (DISM). DISM offline operations on the below editions could not apply security updates because of limits in licensing enforcement. Now, you can use DISM to add security packages during offline image creation for LTSC.

• Windows 10 IoT Enterprise LTSC 2021
• Windows 10 Enterprise G SKU
• Windows 10 Enterprise N LTSC
