Windows 11 Clients: The Group Policy Editors gpedit.msc and GPMC are broken

The Group Policy Editors gpedit.msc and gpmc from the RSAT tools are experiencing functionality issues in Windows 11 due to a bug that causes an overflow error, resulting in incorrect configurations being saved. This issue was first reported by Mark Heitbrink to Microsoft in March 2026, but he has not received feedback. The bug appears to be unique to Windows 11 clients, as tests on Windows Server did not show the problem. Mark documented the bug with submission number VULN-180447 and case number 111952. He described how to reproduce the issue involving the group policy "Delay Foreground download from http" and the decimal value "4294967295," which gets altered to "2147483647" on Windows 11. Mark speculated that the issue might be due to the Windows client using the INT data type instead of unsigned INT, leading to an overflow. He noted that over 50 policies are affected by this MaxValue issue across various components.

Why Windows updates keep getting bigger and more bloated

Monthly updates for Windows 11 from Microsoft now range from 4 to 9 GB, compared to 300 to 500 MB updates two years ago. The increase in update sizes is attributed to the integration of advanced AI features, cumulative delivery of updates, and a fixed monthly update schedule. Cumulative updates bundle all previous updates, leading to larger file sizes, while the monthly frequency forces consolidation of changes into single releases. Users can check what their PC is downloading during an update by navigating to Settings > Windows Update > Advanced options > Delivery optimization > Activity monitor.

I investigated Windows 11’s massive 5GB monthly .msu updates. AI is only part of the problem.

Windows 11 updates have significantly increased in size, with monthly cumulative updates often exceeding 4GB and some approaching 5GB. One update can expand to nearly 9GB when extracted. Microsoft has shifted to delivering Latest Cumulative Updates (LCUs), which include all previous fixes, leading to larger update sizes over time. The introduction of Checkpoint Cumulative Updates aims to reduce this growth by establishing periodic baselines, but the effectiveness has been mixed. The May 2025 cumulative update saw a size increase from approximately 6.5GB to nearly 9GB, with new MSIX files related to semantic search and on-device AI contributing to this growth. Windows Update uses applicability logic to minimize download sizes for users, but enterprises must download full packages, resulting in increased storage costs. The average yearly storage cost for enterprises rose from about 11 GB in 2024 to 52 GB by 2026. Users can check their actual download sizes through the Windows Update settings and Event Viewer logs.

Windows is sabotaging your expensive hardware, and these are the biggest ways how

Modern PCs, even with mid-range hardware, can experience performance issues not solely due to hardware limitations but because of how Windows operates. The operating system runs numerous background services that consume resources, including Connected User Experiences and Telemetry, Diagnostic Policy Service, and Windows Error Reporting. These services log activity and send data to Microsoft, leading to unexpected CPU spikes and disk usage. Startup applications, such as Microsoft Teams and OneDrive, also contribute to longer boot times and increased resource usage. Users should monitor and limit these applications to improve startup performance. Legacy features like SysMain, Windows Search indexing, and automatic folder type discovery can hinder performance on modern systems, as they were designed for older hardware and can cause unnecessary disk activity. Microsoft services like Copilot and OneDrive continuously run in the background, consuming memory and CPU resources, which affects overall system performance. Windows' power management settings prioritize energy efficiency over performance, leading to inconsistent responsiveness and delays during tasks. This conservative approach impacts various components, making the system feel sluggish.

Optimize Windows 11 with these 8 settings tweaks

Windows 11 holds a 62% share of the global Windows desktop market as of January 2026. Users can access the Settings menu by clicking the Start menu and typing "Settings." The Title bar shake feature, which minimizes all open windows when the mouse is jiggled while dragging a window, can be disabled under System > Multitasking. Users can end a task directly from the taskbar by enabling the feature in System > Advanced > End Task. The Start menu can be customized under Personalization > Start to feature more pinned applications and folder icons for frequently accessed directories. The Widgets feature can be disabled under Personalization > Taskbar. To clean up automatic startup applications, users should visit Apps > Startup and disable unnecessary applications. Accessibility settings allow users to increase screen scaling, adjust text size, restore the traditional scrollbar, customize mouse pointer size, and enable the Mouse indicator feature. Privacy can be enhanced by disabling ad tracking in Privacy & security > General. Windows Update settings can be optimized for multiple devices by adjusting Delivery Optimization under Windows Update > Advanced Options.

This hidden Windows 11 setting might be quietly draining your RAM — here’s a quick fix

Microsoft has concluded support for Windows 10 and introduced Windows 11 25H2, which has a feature called Delivery Optimization that is reportedly consuming excessive system memory, leading to sluggish performance on some PCs. A user on Reddit noted that Delivery Optimization may have a memory leak, as its memory consumption is disproportionately high even when not actively needed. This feature is designed to expedite the download of Windows updates and applications by sharing downloaded packages with other devices. However, a recent update has caused the AppX Deployment Service to activate automatically at startup, increasing CPU, memory, and disk usage. Users can disable Delivery Optimization to alleviate memory strain, though this may result in slower download speeds for updates. The steps to disable it involve accessing Windows Update in Settings, navigating to Delivery Optimization, and toggling off the option to allow downloads from other devices.

I disabled these 5 Windows services to improve my PC performance

Windows operating systems have numerous background services that can consume system resources and slow down performance. Users can improve responsiveness by disabling non-essential services. 1. Windows Search: Indexes files and data for quick searches; can tax CPU and RAM. To disable: press Ctrl + R, type services.msc, locate Windows Search, stop the service, and set Startup type to Disabled or Manual. 2. SysMain (formerly Superfetch): Preloads frequently used applications into memory but can lead to unnecessary disk activity on SSDs. To disable: access services.msc, find SysMain, stop the service, and set Startup Type to Disabled. 3. Windows Update Delivery Optimization: Shares update files with other PCs, consuming bandwidth. To disable: go to Settings -> Windows Update -> Advanced Options and turn it off. 4. Remote Desktop Services: Enables remote connections, which can drain resources and pose security risks. To disable: locate Remote Desktop Services in services.msc, stop it, and set Startup type to Disabled. 5. Connected User Experiences and Telemetry: Collects usage data and can transmit sensitive information. To disable: turn off the service and navigate to Settings -> Privacy & Security -> Diagnostics & Feedback to disable Diagnostic data. Additional services that may be disabled include Print Spooler, Fax, Bluetooth Support, and Windows Error Reporting Service for further performance optimization.
