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
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.

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
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
Is Windows 11 denying you access to a data folder: an old drive connected to a new PC, the folder of a former user account, an external drive formatted as NTFS on another computer or a folder restored from a backup? This guide explains why File Explorer blocks access, what the Continue button really does, and how to re
You want to show your Windows 11 PC screen on a TV, a projector or another PC without a cable, but the display does not appear in the list, the connection fails or Windows asks you to plug in a cable? This guide starts from what you observe to find the cause, following Microsoft's support pages. Windows wireless projec
Microsoft launched the Windows 11 2026 Update (version 26H2) on September 29, 2026, and its status page has stated since October 28, 2026 that it is available for all eligible devices. Yet Windows Update still does not offer it to you? This guide helps you find out why, starting from the version installed on your PC, a
The Microsoft certificates used by Secure Boot, issued in 2011, expire in 2026. Windows replaces them with 2023 certificates, normally automatically through Windows Update. Since April 2026, the Windows Security app shows where this update stands. If it says "Not yet updated", shows a yellow badge or a red icon, this g
