Loss of WiFi after migrating from Windows 10 to Windows 11
Hello, I have a desktop Dell PC XPS 8930, which is compatible with Windows 11, according to Microsoft application. I've just migrated to Windows 11 (version 25H2), had an error message "impossible to load iqw64e.sys pilot" at the end of Windows 11 installation (version 25H2), and discovered that my WiFi access had disappeared : WiFi logo is "off", Wi-Fi click button (to set it ON or OFF) has disappeared, only Bluetooth appears as wireless device. Can I activate WiFi on my PC with Windows 11 (issue being I have now no Internet access at all) ? Or should I go back to Windows 10 ? Thanks a lot for your help Philippe
Proposal for Native Kernel Integration of GPU VRAM as Tiered System Memory (NUMA Implementation)
Proposal for Native Kernel Integration of GPU VRAM as Tiered System Memory (NUMA Implementation) 1. EXECUTIVE SUMMARY This proposal outlines a strategic extension to the Windows Memory Manager (Mm) and the Windows Display Driver Model (WDDM). The objective is to expose unallocated Video RAM (VRAM) as a secondary, operating-system-managed memory tier. By treating the GPU as a specialized NUMA (Non-Uniform Memory Access) node via PCIe Resizable BAR, Windows can mitigate current high DDR system memory costs (2026 market conditions) and unlock significant performance gains for I/O-heavy workstation tasks. 2. MOTIVATION & MARKET ANALYSIS The "Dark Silicon" Problem: Modern consumer and workstation GPUs ship with large amounts of high-bandwidth graphics memory. In workloads that do not involve active 3D rendering—such as software compilation, office productivity, or general desktop usage—most of this memory remains unused. This leads to a situation where a substantial portion of a high-performance resource sits idle while system RAM continues to be the primary bottleneck. Economic Efficiency: With volatile prices for high-density DDR5 or DDR6 RAM, upgrading physical system memory is a significant barrier. Utilizing existing VRAM immediately improves hardware ROI (Return on Investment). Local AI Workflows: The rise of local LLMs (Large Language Models) necessitates fast memory paging. Offloading context caches to VRAM offers bandwidth strictly superior to NVMe SSD paging, even when constrained by PCIe bus limits. 3. TECHNICAL FEASIBILITY & ARCHITECTURE To implement this securely and efficiently, I propose moving beyond simple "RAM disks" to a Tiered Memory approach: A. VRAM as a NUMA Node (Software-Defined) Windows already supports NUMA for multi-socket servers. Concept: The kernel driver exposes the GPU VRAM aperture (via Resizable BAR) as a distinct NUMA node. Behavior: The Windows Memory Manager prioritizes standard DDR RAM (Node 0). When Node 0 reaches capacity, instead of paging "cold" pages to the disk/SSD, the Kernel moves them to VRAM (Node 1). Benefit: Latency via PCIe 5.0 (approx. 64 GB/s) is orders of magnitude lower than NVMe SSD latency, keeping the system responsive even under heavy load. B. The WDDM Challenge: Resource Contention A major hurdle is the conflict between Graphics/Compute workloads and Storage workloads. Solution: Implementation of a strict "Kernel-Level Eviction Policy." Mechanism: The OS treats "VRAM-as-RAM" pages as discardable or low-priority. As soon as a DirectX/Vulkan context requests VRAM (e.g., launching a game), the Kernel immediately flushes the VRAM-resident system pages back to the SSD (pagefile) or compresses them into system RAM. Feasibility: WDDM 3.x already handles complex residency management. This would be a logical extension of existing paging logic. 4. SECURITY IMPLICATIONS (Why Open Source is Insufficient) Community-driven solutions (User-mode RAM disks) fail to meet modern security standards required for enterprise adoption: HVCI & VBS Compatibility: Accessing physical memory addresses via PCIe BAR requires Kernel-Mode privileges. Unsigned community drivers violate Hypervisor-Enforced Code Integrity (HVCI). Only a Microsoft-signed driver ensures that the "Secured-Core PC" status remains intact. DMA Protection: Direct Memory Access must be strictly controlled by the IOMMU to prevent peripherals from reading system data. Only a native Windows driver can correctly configure the IOMMU for this specific "VRAM-Swap" usage. 5. STRATEGIC ADVANTAGE FOR WINDOWS Implementing this feature positions Windows as the premier OS for high-performance workstations, bridging the gap between consumer hardware and enterprise needs by maximizing the utility of available hardware resources. ADDENDUM: ARCHITECTURAL PATHWAYS FOR IMPLEMENTATION To further clarify the technical execution, I propose two distinct architectural pathways for the engineering team to consider. These range from a pragmatic storage driver (Path A) to a fully unified memory architecture (Path B). PATH A: THE "VRAM-DRIVE" (STORAGE STACK INTEGRATION) Target: Implementation as a virtual block device (VBD). Complexity: Moderate. Risk: Low. Concept: Instead of extending the system memory pool, the driver creates a high-speed RAM disk exposed to the OS via the Storport driver model. Technical Implementation Details: Driver Model: A Kernel-Mode WDF (Windows Driver Framework) driver acting as a virtual Miniport. Address Mapping: The driver requests the Physical Address of the VRAM aperture (via PCIe BAR resizing) and maps it to a logical disk volume (e.g., Z:). Data Integrity: To prevent data loss during GPU resets (TDR), the driver must register for WDDM power state notifications. On "Power Down" or "Standby," the contents of the VRAM-Drive could be flushed to the NVMe system drive (Hibernation-like behavior). Use Cases: Developer Scratchpad: Target directory for "obj" and "bin" folders during compilation (massive I/O reduction on SSDs). Pagefile Target: Windows allows placing pagefile.sys on secondary drives. Placing it on the VRAM-Drive creates a pseudo-RAM extension. PATH B: THE "TIERED SYSTEM MEMORY" (MEMORY MANAGER INTEGRATION) Target: Transparent extension of the physical RAM pool (NUMA/Tiering). Complexity: High. Risk: Moderate (Requires tight WDDM synchronization). Concept: The VRAM is treated as a secondary memory tier managed directly by the Windows Memory Manager (Mm), invisible to user-mode applications. Technical Implementation Details: NUMA Node Emulation: The driver utilizes the SRAT (System Resource Affinity Table) logic to present the GPU VRAM as a "Headless NUMA Node" (Node 1). This allows the OS to apply standard NUMA policies (e.g., allocate on Node 0 first, spill over to Node 1). Page Management & Migration: Windows currently pages "cold" memory to the disk (backing store). In this model, the Memory Manager would "migrate" pages from DDR (Node 0) to VRAM (Node 1) via DMA before considering the SSD. Latency Hierarchy: L1/L2/L3 Cache <-> DDR RAM <-> VRAM (PCIe) <-> NVMe SSD. The "Game Mode" Eviction Logic (Crucial): WDDM Priority: Graphics workloads must always take precedence. Mechanism: When a DirectX/Vulkan context requires VRAM allocation, the Kernel Driver receives a "Pre-Eviction Callback." Action: The OS immediately marks the system pages residing in VRAM as "modified" and flushes them to the system pagefile, freeing the VRAM for the game within milliseconds. Safety Mechanism: To prevent BSODs during GPU TDR (Timeout Detection and Recovery) events, the Memory Manager should prioritize VRAM allocation for Read-Only or Clean Pages (pages already backed by disk) whenever possible, treating VRAM as a non-guaranteed volatility tier. COMPARATIVE ANALYSIS The primary difference between these approaches lies in user interaction and kernel integration. Path A operates within the Storage Stack, requiring the user to manually manage a new drive volume. It is highly effective for specific I/O-heavy tasks like software compilation but limited by file system overhead. In contrast, Path B operates within the Kernel Core (Memory Manager). It offers a fully automatic experience where the user simply perceives an increase in available system memory. However, Path B relies on PCIe bus latency management and complex WDDM integration to prevent conflicts with gaming workloads.lost image message desktop music in quick list

Windows 11 Recovery Logic and BitLocker Default Issues Causing Boot and Reset Failure
I recently submitted critical feedback through the Windows Feedback Hub regarding a recovery failure scenario that blocked a system reset and was compounded by BitLocker being enabled by default without clear consent. After a normal shutdown, the system failed to boot. A reset attempt was blocked by Windows and required file deletion. At the same time, the system could not boot, making file deletion impossible. This forced a clean install in order to recover functionality. BitLocker was enabled by default, with the recovery key tied to a Microsoft account that was not actively managed. No documentation or guidance was provided to explain this circular recovery logic. I did eventually find a workaround, but a recovery process should never require undocumented steps or technical workarounds simply to regain access to one’s own machine. This represents a design failure, not user error. I submitted this issue as high severity under Install and Update, Backup and Restore, with the problem classified as Inability to use my PC. Feedback Hub link: https://aka.ms/AAzbsvg My key concerns are that boot and reset should not be blocked by opaque security defaults, BitLocker should be opt in and clearly explained during setup, recovery logic must be logically consistent and accessible, and a consumer operating system should not require undocumented workarounds to restore functionality. I also raised broader platform concerns including Windows 11 cost and value compared to macOS annual free operating system updates, ongoing install and uninstall friction caused by legacy registry behavior, and Apple’s predictable recovery process and system reliability. This is not bias. It is professional experience based on decades of use, certification, and paying customer history. I am sharing this here to increase visibility and open discussion, with the hope that engineers and other users can engage with the severity of this real-world failure mode.
Windows Explorer is just lagging, and not showing icons, and crashing
If I select "Date" or "Type" windows cursor shows loading?? and then it stalls. sometimes icons will show and then sometimes it just crashes with no icons. If I try to sort files in any way, it does this. I used disk management to clear all cache/temp files/thumbnails and rebooted but still. Thumbnails delaying and not showing is a major issue.What is the best AI tool for restoring old photos?
Hi everyone, I just digitalized hundreds of old photos and some of them didn't look good. I heard these blurred images can be repaired or enhanced with AI tools. I want to digitally restore a collection of old, damaged family photographs. Many have cracks, spots, and faded areas. I’ve heard AI tools can automate a lot of the repair work, but I’m unsure what is the best AI photo restorer tool for restoring old photos? I'd love to hear about your personal experiences. What has worked well for you in terms of ease of use, quality of results, and handling of complex damage? Free options are a plus, but I’m also open to paid services if they are truly superior. Thanks in advance for your suggestions!
Microsoft Edge's "Preview Channel" Option Disappeared in Windows 11
Previously, I joined the Dev channel through the option "Get early preview versions of Microsoft Edge" in the settings, and the browser version switched to Beta. However, recently Edge seems to have automatically received and rolled back to the official Release version, causing the original preview channel selection entry in the settings to completely disappear, making it impossible to reselect or join any preview programs (Dev, Beta, Canary). Seeking methods to restore the channel option or rejoin the preview versions.
