 ====== Setup ====== ====== Setup ======
 ===== Tweaks ===== ===== Tweaks =====
 +==== Context Menu ====
 +Yes, the classic {86ca1aa0-34aa-4e8b-a509-50c905bae2a2} registry tweak is broken in the latest Windows 11 updates (26H2 and November 2026 updates like KB5127936 / KB5132061). Microsoft introduced a redesigned, customizable context menu engine that completely ignores that legacy registry key.
 +Depending on whether you want to force the old menu back or adapt the new one, you have three working options:
 +
 +1. Force the Classic Menu Back Using ViVeTool (Workaround)
 +
 +Because the new context menu engine overrides the registry, you must disable the new context menu feature ID first so Windows recognizes your registry tweak again.
 +1. Download ViVeTool from the official ViVeTool GitHub releases page and extract the ZIP file to a folder (e.g., C:\ViVeTool).
 +2. Open Terminal (Admin) or Command Prompt (Admin) and navigate to that folder (e.g., cd C:\ViVeTool).
 +3. Run the following command to disable the new context menu engine:cmd
 +vivetool /disable /id:60813048
 +Use code with caution.
 +4. Ensure the classic registry key is still applied by running:cmd
 +reg add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve
 +Use code with caution.
 +5. Restart your PC for the change to take effect.
 +(Note: Future Windows feature updates may re-enable this feature ID, requiring you to run the ViVeTool command again.)
 +
 +2. Use the New Built-in Customization Settings (No Third-Party Tools)
 +
 +Microsoft replaced the old workaround with native controls designed to reduce the need for the legacy menu.
 +• Open Menu Settings: Go to Settings > Personalization > Context menu.
 +• Move App Extensions to Top Level: Enable the option to show third-party app commands directly on the main right-click menu instead of burying them in an App Extensions submenu.
 +• Restore Missing Commands: Toggle on commands that are hidden by default, such as Send to, Print, Create shortcut, Copy as path, and Rotate image.
 +• Re-enable "Show more options": Check under Additional options in the same settings page to restore the Show more options button at the bottom of the menu if it was hidden.
 +
 +3. Quick Keyboard Shortcut (Zero Setup)
 +
 +If you prefer not to use third-party tools like ViVeTool, holding Shift + Right-Click on any file, folder, or desktop area still bypasses the modern menu and immediately opens the classic Windows 10 context menu.

 +==== Connection to external monitors drops ====
 +Windows 11 can lose connection to multiple external monitors when a screen saver starts due to aggressive power-saving states or corrupted display topology caches in the graphics registry.
 +
 +Troubleshooting Steps
 +
 +• Disable the Screen Saver: Turn off the screen saver temporarily via Settings > Personalization > Lock screen > Screen saver to see if the dropouts stop entirely.
 +• Update Graphics Drivers: Install the latest clean drivers directly from NVIDIA, AMD, or Intel rather than relying on basic Windows Update packages.
 +• Clear Display Cache: Go to Registry Editor (regedit), navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers, and delete the sub-folders Configuration, Connectivity, and ScaleFactors, then reboot your PC to rebuild the monitor topology.
 +• Check Power Management for USB/Hubs: If your 2nd and 3rd monitors run through a dock or adapter, open Device Manager, find your USB Hubs/Controllers, right-click Properties > Power Management, and uncheck "Allow the computer to turn off this device to save power."
 +• Force Rescan: Press Windows Key + Ctrl + Shift + B to restart your graphics driver, or go to Settings > System > Display > Multiple displays and click Detect.
 +=== next ===
 +When dealing with NVIDIA graphics driving multiple monitors over USB-C, the screensaver disconnect issue is usually triggered by a combination of NVIDIA's power management states and Windows aggressive USB power saving features. When the screen saver starts, the system drops the power profile, causing the USB-C Alt-Mode video signal to drop and lose its handshake entirely.
 +Try adjusting these settings to fix it:
 +
 +1. Disable USB Selective Suspend & PCI Express Link State
 +
 +By consensus on the Microsoft Support Community, changing advanced power profiles keeps the USB-C channels active when the system idles:
 +1. Press Win + R, type control powercfg.cpl,,1, and hit Enter.
 +2. Scroll to USB settings > USB selective suspend setting, and change it to Disabled.
 +3. Scroll to PCI Express > Link State Power Management, and change it to Off (or Maximum Performance).
 +4. Click Apply and OK.
 +
 +2. Configure the NVIDIA Control Panel Power Mode
 +
 +NVIDIA's drivers sometimes put the GPU into a deep sleep state when a screensaver triggers, breaking the multi-monitor alignment.
 +1. Right-click your desktop and open the NVIDIA Control Panel.
 +2. Go to 3D Settings > Manage 3D Settings.
 +3. In the Global Settings tab, look for Power management mode.
 +4. Change it from Optimal power to Prefer maximum performance.
 +
 +3. Adjust USB Root Hub Properties
 +
 +If you are using a USB-C dock or separate USB-C to DisplayPort/HDMI cables:
 +1. Right-click the Start menu and select Device Manager.
 +2. Expand the Universal Serial Bus controllers section.
 +3. Right-click on USB Root Hub (or USB4 Root Router / Thunderbolt Controller if available) and choose Properties.
 +4. Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power." Repeat this for any other USB hubs listed.
 +
 +4. Check NVIDIA Surround / Multi-Display Performance Mode
 +
 +If Windows treats the screensaver as a "3D application," it can shift how the GPU prioritizes ports.
 +1. In the NVIDIA Control Panel, go to 3D Settings > Manage 3D Settings.
 +2. Look for Multi-display/mixed-GPU acceleration (if present on your driver version) and ensure it is set to Multi-display performance mode.
