26063 deduplication data corruption is still there.
From Server 2022 up to this newest 26063 build, they all have the same problem, as described here: https://techcommunity.microsoft.com/t5/windows-server-insiders/server-vnext-26040-and-server-2022-deduplication-data-corruption/m-p/4047321 I am out of energy for today and give up for today. It seems to be impossible to get Microsoft to care for actual OS bugs instead of marketing.

Windows 11 automatically restarting after install security Update — With GPO and WSUS.
Hi everyone, I’m facing a strange behavior with Windows 11 devices that receive updates through WSUS and are fully managed via Group Policy. Here’s the scenario: We have a GPO configured as follows: -Configure Automatic Updates → 4 (Auto download and schedule the install) -Scheduled installation every day at 10:00 -Install during automatic maintenance → disabled -Active Hours configured -Turn off auto-restart for updates during active hours → Enabled -Update deadlines set to 0 (to avoid any forced restart) -No other restart-related policies set in the domain Even with this configuration, after updates are installed, Windows 11 shows the following message: “Your organization manages update settings. We will restart and install this update at X minutes.” And then the device automatically restarts, even when: -a user is logged in -it is outside Active Hours -deadlines are disabled -no-auto-restart is enabled This behavior does not happen on Windows 10 — only on Windows 11.
Unable installing extensions from a different feed
I added a new feed from a path, and WAC is telling me it can't read the feed or update the corresponding catalog. I followed the instructions in this link: "https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/configure/using-extensions#installing-extensions-from-a-different-feed". In fact, since my network isn't connected to the internet, I also followed the instructions in this other link: "https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/configure/using-extensions#installing-extensions-on-a-computer-without-internet-connectivity". Regarding adding a file share as a source, it must meet the criteria outlined in this link: "https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/configure/using-extensions#installing-extensions-from-a-different-feed". However, I'm getting these error messages and therefore don't have any extensions available to add:
Windows Admin Center 2410 not updating Server 2025
Hi, I have 3 new 2025 servers all updated and on the domain. Windows Admin center is working fine with all other servers (2012, 2016, 2019, and 2022). For these 3 new servers, I can connect and login through Adm Center and when I choose the "updates" tab the circle in the middle of the screen spins indefinitely. It never even shows if updates are available or not, it just spins. If I log onto the servers locally, I can see and install updates manually. But when I go back and connect through ADM Center, I just get the spinning circle. I currently only have 3 2025 servers, so for me it appears to be an issue with how they talk to ADM Center concerning updates. (and this makes me hesitate to update other servers) I've tried RDP, registry, Powershell, etc (all through ADM Center). It ALL works, but updates never do. Additionally the 2025 servers are able to communicate just fine to report update status to our WSUS server. If I click the "update history" tab on the updates page in Admin Center, I then see an error, but not sure what would be denying anything, when the connection already seems to be made: "Message We couldn't check update history. Error: (1) RemoteException: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) (2) RemoteException: The property 'ServerSelection' cannot be found on this object. Verify that the property exists and can be set. (3) RemoteException: You cannot call a method on a null-valued expression. (4) RemoteException: You cannot call a method on a null-valued expression." I tried to temporarily disable the firewall with no change in behavior. The account I'm using is a domain admin account and also added to the local admin group for testing.VM Load balance is not working

2025-10 Cumulative Update for Windows Server 2019 (KB5066586) Undoes Update on Reboot
We have a Windows Server 2019 Standard which will not install the 2025-10 Cumulative Update for Windows Server 2019 (KB5066586) update. The installation part goes fine, but when the server is rebooted to finalize the update, it goes into "Undoing changes". Then it reboots again, and I am back where I started. The error code is 0x8007000d. I have done the following to debug this: Ran System File Checker sfc /scannow. No errors found. DISM /Online /Cleanup-Image /ScanHealth. No errors found. Ran Windows Update Troubleshooter. No errors found. Shut down Windows Update services. Renamed SoftwareDistribution and Catroot2 folders. Restarted services. No change. Ran ScanDisk. No errors found. Disabled antivirus. No change. Ran Disk Cleanup and manually deleted additional temp files. No change. Checked Event Viewer. Only error is Event 20 which is a failure of the Windows Update Agent. I am out of ideas. If anyone has some, I would much appreciate the help. I am out of ideas.

Best Regards SGAllow Hyper-V VM attached to Internal Switch access internet and host folders
I have Created an internal switch and attached it to 4 VMs (for a lab setup) on a win2k19 hyper-V host. The hyper-V is in the my local home subnet 192.168.0.1. The 4 VMs are configured with following IPs and gateway. VM1 10.10.0.10 -DefaultGateway 10.10.0.1 VM2 10.10.0.11 -DefaultGateway 10.10.0.1 VM3 10.10.0.12 -DefaultGateway 10.10.0.1 VM4 10.10.0.13 -DefaultGateway 10.10.0.1 In the lab document, it is not indicated how/where to assign the 10.10.0..1 IP? When I check the vEthernet (Private Network), It has "DHCP" for IP and got my local DNS IP. Checking its status, I see DHCP Enabled: Yes Autoconfiguration IPv4 Address: 169.254.32.39 IPv4 Subnet Mask: 255.255.0.0 IPv4 Default Gateway: Not sure where this 169.254.... IP comes from? I tried assigning the IP 10.10.0.1 to this but it fails. In fact I need to allow VMs to access some host folders as well as internet to download some Microsoft tools. Thanks for your help
Securing ldap in WIndows AD
Hello everyone. I would like to secure the use of LDAP within an Active Directory domain. My domain has three Windows 2022 DCs. Searching online, I found these suggestions: Enforce LDAPS (LDAP over SSL/TLS) Disable Plain-text LDAP Bindings Block or Restrict Port 389 (Optional but Recommended) Enable Channel Binding Tokens (CBT) Does it make sense to only allow certain users to browse LDAP? Could limiting LDAP browsing to certain users cause problems? Thanks
Breaking Certutil changes in WS2025
I noticed yesterday that a certutil command I thought I could always rely on no longer works in Server 2025: >certutil -cainfo xchg CertUtil: -CAInfo command FAILED: 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER) CertUtil: The parameter is incorrect. Executing certutil -cainfo xchg was a handy command which would ask the local certificate authority to output it's current CA Exchange certificate in Base64 format. If the CA didn't have a valid exchange cert at the time, it would immediately create a new one. Think of a CA Exchange certificate as a short-lived TLS cert which the CA provides clients when they need to upload private key material for archival. Anyway, looking at the help for certutil, the command still exists, however, it requires a new parameter: xchg [Index] -- CA exchange cert So, I figured [Index] had to refer to the CA certificate index. When you initially deploy an ADCS certification authority, the CA's initial certificate is at index 0. When you renew/re-key the CA, the new CA cert is at index 1. I tried using 0 for the [Index] parameter. No dice: >certutil -cainfo xchg 0 CertUtil: -CAInfo command FAILED: 0x80070057 (WIN32: 87 ERROR_INVALID_PARAMETER) CertUtil: The parameter is incorrect. I can't think of what else that parameter would be. Has anyone been able to successfully used this command on WS2025? If so, please share how!
