Announcing Windows Server Preview Build 26063 Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions, Annual Channel for Container Host and Azure Edition (for VM evaluation only). Branding has been updated for the upcoming release, Windows Server 2025 in this preview - when reporting issues please refer to Windows Server 2025 preview. What's New Windows Server Flighting is here!! If you signed up for Server Flighting, you should receive this new build automatically later today. For more information, see Welcome to Windows Insider flighting on Windows Server - Microsoft Community Hub [NEW] The new Feedback Hub app is now available for Server Desktop users! The app should automatically update with the latest version, but if it does not, simply Check for updates in the app’s settings tab. [NEW] Win32-OpenSSH server component is now installed by default. Starting in Windows Server 2025 the Win32-OpenSSH server side component (SSHD) will ship installed by default. Previously, the Win32-OpenSSH server component shipped as an optional feature that needed to be installed. Additionally, there is a new option in the Server Manager UI to enabled/disable SSHD, as well as a new group, “OpenSSH Users”. To use SSHD, the feature only has to be enabled, not installed. When enabled, SSHD is allowed only on private networks on default port 22. The following new features are specific to Windows Server with Desktop Experience only. Some of these will require running the OS on physical systems AND having the right drivers on hand. [NEW] Try the "WinGet" command line utility on Windows Server! The WinGet command line utility enables installing applications and other packages from the command line. Simply type winget on the command line for a list of available commands to get started. For example, you can install the latest version of Powershell using the winget command: winget.exe install 'Microsoft.PowerShell' [NEW] Desktop Wallpaper: Our newly modernized desktop experience now includes an updated desktop wallpaper. Additions to <Settings>Accounts: Email & Accounts is now consistent with Windows 11. Please note, domain join will still be necessary for most scenarios. Call to action: Please try adding Microsoft accounts and/or work accounts along with relevant apps that take advantage of this.

If you encounter this issue, please upgrade to this newer build using the ISO media download option. Download Windows Server Insider Preview (microsoft.com) [NEW] VMs created using ISO media may not boot: Some users may encounter boot issues when creating Gen 2 VMs using this build (26063) and attempting to set the DVD ISO as boot preference. The new VM is unable to boot through the ISO and skips to subsequent boot options. This will be addressed in a future release. [NEW] Access denied error when using Diskpart --> Clean Image on Winpe.vhdx VMs created using WinPE: Create bootable media | Microsoft Learn. We are working to resolve this issue and expect to have it fixed in the next preview release. Download Windows Server Insider Preview (microsoft.com) Flighting: The label for this flight may incorrectly reference Windows 11. However, when selected, the package installed is the Windows Server update. Please ignore the label and proceed with installing your flight. This issue will be addressed in a future release. Setup: Some users may experience overlapping rectangle voids following mouse clicks during "OOBE" setup. This is a graphics rendering issue and will not prevent setup from completing. This issue will be addressed in a future release. WinPE - Powershell Scripts: Applying the WinPE-Powershell optional component does not properly install Powershell in WinPE. As a result, Powershell cmdlets will fail. Customers who are dependent on Powershell in WinPE should not use this build. If you are validating upgrades from Windows Server 2019 or 2022, we do not recommend that you use this build as intermittent upgrade failures have been identified for this build. This build has an issue where archiving eventlogs with "wevetutil al" command causes the Windows Event Log service to crash, and the archive operation to fail. The service must be restarted by executing "Start-Service EventLog" from an administrative command line prompt. If you have Secure Launch/DRTM code path enabled, we do not recommend that you install this build. Available Downloads Downloads to certain countries may not be available.

Announcing App Control for Business (aka WDAC) with OsConfig Windows Defender Application Control (WDAC) for business is a software-based security layer that reduces attack surface by enforcing an explicit list of software that is allowed to run. For Windows Server 2025, we have provided Microsoft defined ‘default policy’ which can be applied to the server via PowerShell cmdlets, powered by our ‘Security configuration platform called ‘OSconfig’. For more detailed information, please refer here. App control feature provides two main operation modes, Audit mode and Enforcement mode. In Audit mode, untrusted code is allowed to run, and events are recorded. In Enforcement mode, untrusted code is blocked, and events are recorded. To learn more about Application Control for Business-related events, see List of Events. As part of WS 2025, we want to make it easier for customers to deploy Application control policies in audit mode and facilitate enforcement mode via local tooling/PowerShell experience. There will be no Application Control policy in audit mode which will be enabled by default in WS 2025. The only way to add Application Control for business is via OSconfig tool. Base policies are integrated in OSconfig (unsigned). Using these policies, users will be able to add supplemental policies to existing base policies (to customize the default base policy. Caution -- Production signed Windows Server 2025 build is needed since the App Control for Business policy doesn't allow flight signing binaries. Prior to general availability, please download the production signed preview by visiting the Microsoft Eval Center to try out the new features and experiences that Windows Server has to offer. 1.1 Application Control for Business – Apply Pre-requisites: You have installed ‘OSconfig Powershell Module’ to configure Application Control for Business. Install the package providers by running the following commands in an elevated PowerShell window: Install-PackageProvider -Name NuGet -Force Install-Module PowerShellGet -AllowClobber -Force Close powershell window. Open a new elevated PowerShell window and run the commands below to install the OSConfig PowerShell module: Install-Module -Name Microsoft.OSConfig -AllowPrerelease -Force 1.2 Application Control for Business – Apply default polices: Next step is to install the default policies in audit mode: Set-OSConfigDesiredConfiguration -Scenario AppControl\WS2025\DefaultPolicy\Audit -Default Set-OSConfigDesiredConfiguration -Scenario AppControl\WS2025\AppBlockList\Audit -Default 1.3 Application Control for Business – Post apply check policies are present in your machine: Run the citool to confirm the policies are in place. Hit enter twice after running the command below: citool -lp | findstr /I "WS2025" You should see ‘policies named’ in the list: BlockUMCI_Microsoft_WS2025_Audit AllowMicrosoft_WS2025_Audit 1.4 Application Control for Business – After applying ensure policies are present in your machine: Run a 3rd party application of your choice, verify that a block event was emitted for the 3rd party app you ran, and no block event was emitted for any 1st party apps you ran. Check in Event Viewer >> Filter Current log >> Filter Audit events 3076 >>Check event for the 3rd party app. 1.5 Application Control for Business – Apply supplemental policies: Reset filter: In the right panel, click on Filter Current Log... and click clear to remove the previously applied filters. In Event Viewer, still under "Applications and Services Logs" -> Microsoft -> Windows -> CodeIntegrity -> Operational, select the Save All Events As... option in the right panel and save the evtx file to the location of your choice. Share the evtx file to a Windows client device. On the Windows client device, install and start the WDAC Wizard. Note: The WDAC wizard installer will download .NET 8.0 if you don't have it already In the WDAC Wizard, select Policy Editor -> Convert Event Log to a WDAC Policy, then click on the Parse Log File(s) button under Parse Event Log evtx Files to Policy. Select the evtx file and click Next. Click on +Add Allow for all items you want to add to the policy, then Next. The WDAC Wizard will share the location of the XML file on the next page. Copy the XML file to your server device. On the server device, run the following commands: $policyPath = "<path to the XML file>" # Reset GUID (best practice) Set-CIPolicyIdInfo -FilePath $policyPath -ResetPolicyID # Set Policy Version (VersionEx in the XML file) $policyVersion = "1.0.0.1" Set-CIPolicyVersion -FilePath $policyPath -Version $policyVersion # Set Policy Info (PolicyName, PolicyID in the XML file) Set-CIPolicyIdInfo -FilePath $policyPath -PolicyID "<App name>-Policy_$policyVersion" -PolicyName "<App name>-Policy" # E.g. Set-CIPolicyIdInfo -FilePath $policyPath -PolicyID "Chrome-Policy_$policyVersion" -PolicyName "Chrome-Policy" $base = "{9214D8EE-9B0F-4972-9073-A04E917D7989}" Set-CIPolicyIdInfo -FilePath $policyPath -SupplementsBasePolicyID $base #Set the new policy into the system Set-OSConfigDesiredConfiguration -Scenario AppControl -Name Policies -Value $policyPath Go through step 2 again. This time, there shouldn't be any new audit events for the application you ran. 1.6 Application Control for Business – Query the list of active and non-active policies 1. Run the following command to see the current policies in effect: (Get-OSConfigDesiredConfiguration -Scenario AppControl).Value.PolicyInfo | Where-Object { $_.IsEffective -eq $true } 2. Run the following command to see the policies that are not active: (Get-OSConfigDesiredConfiguration -Scenario AppControl).Value.PolicyInfo | Where-Object { $_.IsEffective -eq $false } 1.7 Application Control for Business – Remove the policies via OSConfig 1. Remove the Application control policies by running the commands below: Remove-OSConfigDesiredConfiguration -Scenario AppControl\WS2025\DefaultPolicy\Audit Remove-OSConfigDesiredConfiguration -Scenario AppControl\WS2025\AppBlockList\Audit 2. Verify that the policies are no longer effective. Hit enter twice after running the command below. You should NOT see the following: Friendly Name: BlockUMCI_Microsoft_WS2025_Audit Friendly Name: AllowMicrosoft_WS2025_Audit Warning: We recommend using OSconfig to remove the policies otherwise the drift control will be in still in effect and it will re-apply. 1.8 Azure Monitor - Application Control for Business We have created a new Azure Monitor workbook to alleviate the burden of reviewing Audit or Block events being emitted by the Operating System when Application Control for Business is activated. This workbook can help you get insights on file audit and block activity, as well as policies activity. Here is a comprehensive list of usages for this workbook: Collect and send to Log analytics workspace Windows Event logs for App Control for business. Identify file and policy events activities, providing various dashboards, charts, filter and export capabilities to help customers analyze and troubleshoot App Control policies effects and status. Refine your App Control for business policies, by exporting the workbook data and ingesting it in WDAC Wizards. For more information, see WDAC Wizard documentation. To start using the Azure Monitor workbook for Application Control for Business (Preview) please go to the GitHub repo in the Azure Monitor here. We value your feedback! Please provide feedback as to what is working and what needs to be improved as your feedback is extremely valued to make the product experience better.

Announcing Windows Server Preview Build 26227 Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions, Annual Channel for Container Host and Azure Edition (for VM evaluation only). Branding has been updated for the upcoming release, Windows Server 2025, in this preview - when reporting issues please refer to Windows Server 2025 preview. If you signed up for Server Flighting, you should receive this new build automatically. What's New [NEW] Delegated Managed Service Accounts (dMSA) A new account type known as delegated Managed Service Account (dMSA) is now available that allows migration from a traditional service account to a machine account with managed and fully randomized keys, while disabling original service account passwords. Authentication for dMSA is linked to the device identity, which means that only specified machine identities mapped in AD can access the account. Using dMSA helps to prevent harvesting credentials using a compromised account (kerberoasting), which is a common issue with traditional service accounts. To learn more about dMSA, visit https://learn.microsoft.com/en-us/windows-server/security/delegated-managed-service-accounts/delegated-managed-service-accounts-overview. More Server Message Block (SMB) protocol changes. Starting with Build 26097 and higher, we are introducing the following Server Message Block (SMB) protocol changes for QUIC, signing, and encryption: SMB over QUIC client and server disable: Administrators can now disable the SMB over QUIC client and SMB over QUIC server options with Group Policy and PowerShell. SMB over QUIC client and server connection auditing: Successful SMB over QUIC client and SMB over QUIC server connection events are now written to the event log to include the QUIC transport. SMB signing and encryption auditing: Administrators can now enable auditing of the SMB server and client for support of SMB signing and encryption. This shows if a third-party client or server doesn’t support SMB encryption or signing. You can configure these settings with PowerShell and Group Policy. For details on configuring these new settings, review https://aka.ms/SMB74MDNP. For more information on SMB over QUIC in Windows and Windows Server Insider Preview builds, review https://aka.ms/SMBoverQUICServer and https://aka.ms/SmbOverQuicCAC. For more information on SMB signing and encryption in Windows and Windows Server Insider Preview builds, review https://aka.ms/SmbSigningRequired and https://aka.ms/SmbClientEncrypt.

Known Issues [NEW] Secure-boot Gen2 VMs created using ISO media may not boot: Some users may encounter boot issues when creating secure-boot Gen 2 VMs. Disabling secure-boot allows the Gen2 VM to boot successfully. This will be addressed in a future release. Upgrade does not complete: Some users may experience an issue when upgrading where the download process does not progress beyond 0%. If you encounter this issue, please upgrade to this newer build using the ISO media download option.

We are working to resolve this issue and expect to have it fixed in the next preview release. Download Windows Server Insider Preview (microsoft.com) Flighting: The label for this flight may incorrectly reference Windows 11. However, when selected, the package installed is the Windows Server update. Please ignore the label and proceed with installing your flight. This issue will be addressed in a future release. Setup: Some users may experience overlapping rectangle voids following mouse clicks during "OOBE" setup. This is a graphics rendering issue and will not prevent setup from completing. This issue will be addressed in a future release. WinPE - Powershell Scripts: Applying the WinPE-Powershell optional component does not properly install Powershell in WinPE. As a result, Powershell cmdlets will fail. Customers who are dependent on Powershell in WinPE should not use this build. If you are validating upgrades from Windows Server 2019 or 2022, we do not recommend that you use this build as intermittent upgrade failures have been identified for this build. This build has an issue where archiving eventlogs with "wevetutil al" command causes the Windows Event Log service to crash, and the archive operation to fail. The service must be restarted by executing "Start-Service EventLog" from an administrative command line prompt. If you have Secure Launch/DRTM code path enabled, we do not recommend that you install this build. Available Downloads Downloads to certain countries may not be available.
