File Explorer's preview pane no longer shows your downloaded PDFs, documents or HTML files, and instead says: "The file you are attempting to preview could harm your computer. If you trust the file and the source you received it from, open it to view its contents." This is neither a virus nor a bug: it is a protection
On many laptops and keyboards released since 2024, the manufacturer replaced the Right Ctrl key (or sometimes the Context Menu key) with a Copilot key. As a result, your Right Ctrl shortcuts no longer work, and a screen reader that relied on that key becomes awkward to use. In 2026, Microsoft added a Windows 11 setting
Hyper-V is the hypervisor built into Windows: it lets you create virtual machines without extra software. Microsoft states that there is no Hyper-V download: it is an optional Windows feature, which only appears if the edition and the hardware allow it. When Hyper-V is missing from the list, greyed out, or Hyper-V Mana
You open an Excel, Word or PowerPoint file received by email or downloaded, and a red security risk banner says: "Microsoft has blocked macros from running because the source of this file is untrusted". This is not a fault: since 2022, Office on Windows blocks VBA macros in files from the Internet by default, because t
Windows 11 includes OpenSSH as an optional feature: the client (the ssh command) to connect to another machine, and the server (the sshd service) to accept incoming connections. When the connection fails, the cause is almost always one of four things: a missing component, a stopped service, a closed firewall, or a publ
Recall is the Windows 11 feature that saves snapshots of your screen so you can find later what you have seen. It cannot be found, the Windows + J shortcut does nothing, or snapshot saving refuses to turn on? Recall depends on strict hardware and security requirements: most cases are explained by one of them. Problem R
You want to enlarge drive C: or another partition, for example after cloning Windows to a bigger SSD or shrinking another partition, but in Disk Management the Extend Volume option is greyed out. Windows only enlarges a volume under specific conditions: most of the time, the free space is simply not in the right place.
An older program or game requires .NET Framework 3.5, and the installation fails: a "Windows couldn't complete the requested changes" window, error code 0x800F0906, 0x800F081F or 0x800F0907, or a checkbox missing from Windows features. Since Windows 11 26H1, Microsoft has changed how this component is installed: the ri
You type python in a terminal and Windows opens the Microsoft Store, or the command is not found even though Python seems to be installed. Since Python 3.14, the recommended installation method on Windows is the Python install manager, which provides the python, py and pymanager commands. Most failures come from a Wind
You type a winget command in Command Prompt or PowerShell and Windows says the term is not recognized, or the command closes without displaying anything. WinGet, the Windows package manager, is not a separate program: it ships with the App Installer component, delivered through the Microsoft Store. The fault almost alw
Windows 11 refuses to copy, move, extract or delete a file, saying that its name or path is too long? The problem almost always comes from an old Windows limit: 260 characters for the full path of a file, folders included. This guide explains how to recognise it and work around it, from the simplest solution (shortenin
You want to delete, rename or move a file, and Windows 11 refuses, saying it is open in a program? Windows protects a file as long as a process keeps it open: this is not a fault, but you need to identify that process. This guide offers a progression from the simplest to the most technical, with Microsoft's free tools
