Windows11 system deleted Windows Defender. How can I restore it?
I recently ran a batch file that ended up deleting Windows Defender from my computer. This happened some time ago, and unfortunately, I don’t have any system restore points set up beforehand. I’ve been trying to find a way to get Windows Defender back but haven’t had any luck so far.
4K monitor Win11 scaling causes abnormal mouse movement
After replacing the monitor with a new 4K display, when the Windows 11 scaling is set to 150%, the mouse encounters an “obstacle” at the Y-axis position of 1440 (1728 at 125% scaling), preventing vertical movement. It can only move horizontally and requires acceleration to force through. Hardware issues with the mouse have been ruled out (replacing the G502 did not resolve the issue), and this phenomenon does not occur on the Windows 10 system. System version: Windows 11 Pro 23H2 (22631.4112).The Windows 11 login screen lacks a password field and displays a password error.
The Windows login screen fails to display the password input field. After clicking “Login,” it prompts that the password is incorrect (though the actual password is correct), preventing access to the system. Seeking an effective solution.
Upgrade to windows 11 Pro from unlicensed Home version
Hi I have build a computer and I downloaded unlicensed Windows 11 Home to a usb drive (from microsoft) and installed it as operative system. Then my manager bought a 11 pro license key (misunderstood each other) instead of windows 11 home license key. Now I try to write in the 11 pro license key but it doesn't work. I get an error message when I push next. I thought it would upgrade to pro automatically. So my question is: does this not work? what should I do? I don't want to reformat the computer since I have bought office package and another program.Save the date: Windows Office Hours - August 21, 2025

Windows 11 Pro for Workstation. Broken features, lack of support.
There are two reasons I wanted to deploy workstation edition for a new system I'm working on. ReFS and RDMA. I'm unable to use ReFS and in my research and troubleshooting I've found out there is very little support, documentation and knowledgeable people in Microsoft that can help. Workstation edition was properly installed from the start. I've tested the ISO available at the download windows 11 site and the visual studio Business Edition ISO. I've tested both 23H2 and 24H2. ReFS is not available as a filesystem option in explorer's context menu, storage spaces or disk manager. Creating a storage space volume in PowerShell and setting returns an error that the filesystem is not supported. I suspect there might be a problem with my work account and the Windows Business Digital license it applies. I brought the issue up with MS365 support, but they didn't want to take it and pushed me off to the team for activation support. They weren't helpful, they didn't know much about workstation edition. I can see both the key and digital subscription are both active. There's absolutely no documentation regarding any of the features workstation edition enables. Even when starting support tickets or reviewing windows documentation there is no mention of workstation edition. There is an option for enterprise edition. I'm at a loss of how Microsoft supports this edition of windows and where to get any help.HP 15s-fq2811nc (72H94EA): Win 11 Install - SSD Not Found (Missing IRST Driver)
Hello everyone, I'm facing a critical issue while attempting a fresh installation of Windows 11 on my HP Laptop 15s-fq2811nc (Product Number: 72H94EA). The system is currently running a Linux distribution, and I'm trying to replace it with Windows 11. During the Windows 11 setup, after selecting the language and accepting the terms, I reach the "Where do you want to install Windows?" screen. The installer fails to detect my internal storage drive (a 512 GB PCIe NVMe M.2 SSD), and the list of drives is completely empty. The error message explicitly states: "We couldn’t find any drives. To get a storage driver, click Load driver." Based on my research, this problem is a well-known issue with Windows 11 installation on systems equipped with 11th-generation Intel Core processors (in my case, the Intel Core i3-1125G4). These platforms often require the Intel Rapid Storage Technology (IRST) driver to be loaded manually during the installation process to recognize the NVMe SSD. I've already tried some basic troubleshooting steps, including checking the BIOS settings to ensure the SATA mode is set to AHCI, but this did not resolve the issue. I would be extremely grateful if someone could provide the following: A direct link to the correct IRST driver package for my specific laptop model, the HP 15s-fq2811nc. I've tried searching on the general HP support site, but it can be difficult to find the exact driver file that needs to be loaded. Clear, step-by-step instructions on how to load this driver during the Windows 11 installation. This includes what files to place on a separate USB drive and the exact steps to follow in the setup wizard. Any other potential solutions or workarounds that may be relevant, such as specific BIOS settings for this model. This is a complete blocker for me, and I cannot proceed with the installation without this driver. Any help from the community would be highly appreciated. Thank you!
