What is SMBv1? Server Message Block version 1 (SMBv1) is a network file-sharing protocol developed in 1983. It enables file and printer sharing across Windows networks using specific TCP/IP ports. It was the primary file-sharing protocol for Windows systems until SMBv2 replaced it in 2007.

Windows 11 25H2: Changes, installation, and user feedback – 4sysops
Enablement package approach Windows 11 25H2 will be delivered as an enablement package (eKB), sharing the same servicing branch as version 24H2.

VS Code extension Cline: AI-automated scripting and CLI administration - A PowerShell example
In a previous post about the new AI features in the Warp terminal, I suggested that AI interfaces would eventually replace the CLI and facilitate the automation of script generation. The Cline extension for Visual Studio Code is a significant step in this direction, allowing you to create scripts using natural language, execute them with AI support in the terminal, rely on AI to analyze shell output and respond to errors.
Add icons to Windows 11 Start with Group Policy
The significant technical changes in the Windows 11 Start menu become evident when attempting to deploy a standardized Start menu across multiple computers. The XML export method familiar from Windows 10 is no longer supported; instead, a JSON configuration must now be deployed via MDM.

As a result, logging in with Outlook 2013 becomes impossible.
