Hi everyone,

I have compiled a new Experimental Build (Branch: feat/add-id-59765208 / Commit: 36f949d) to test a new Feature ID.

The Goal:
This feature may allow the Xbox Full Screen Experience (FSE) to launch natively at boot without relying on the Physical Panel Dimensions Override (SetPanelDimensions / PhysPanelCS / PhysPanelDrv).

If successful, this would enable FSE on Desktop PCs and Laptops natively, eliminating the startup race condition.

Supported Windows Builds for this Test:
This feature appears to be available ONLY in the following build (and newer):

  • 26220.7271 (25H2 Dev Channel)

How to Test:

  1. Uninstall your current version, then download and install this experimental build.
  2. Enable the Xbox Full Screen Experience in the tool.
  3. Crucial Step: Disable the Override
    Since this build still includes PhysPanelCS as a fallback, you must disable it to verify if the new Feature ID works on its own.
    • For Standard Desktop/Laptop Users:
      Open Task Scheduler, find the task XFSET-SetPanelDimensions, and Disable it.
    • For Surface Users (DeviceForm Reset):
      You cannot disable the task because you still need the registry fix. Instead, edit the task Action. Change the dimensions 155 87 (7-inch) to 500 300 (approx. 23-inch size), but keep the reg argument.
      • Example: Change set 155 87 reg to set 500 300 reg.
  4. Restart your PC.
  5. Verification: Please report if FSE launches successfully at boot.

Important: Please also attach the log files located at:

  • "C:\Program Files\8bit2qubit\Xbox FullScreen Experience Tool\XboxFullScreenExperienceTool.log"
  • "C:\Program Files\8bit2qubit\Xbox FullScreen Experience Tool\XboxFullScreenExperienceTool.log.bak"

(Note: You need to rename the .bak file to .txt or .log to upload it to GitHub.)

我編譯了一個新的 實驗版本 (分支: feat/add-id-59765208 / Commit: 36f949d),用於測試一個新的 Feature ID。

測試目標:
此功能可能允許 Xbox 全螢幕體驗 (FSE) 在開機時原生啟動,而不再需要依賴「實體面板尺寸覆寫」 (SetPanelDimensions / PhysPanelCS / PhysPanelDrv)。

若測試成功,FSE 將可直接在桌上型電腦與筆記型電腦上運作,消除啟動競態條件 (Race Condition)。

支援測試的 Windows 版本:
此功能似乎 在以下特定版本(及更新版本)中生效:

  • 26220.7271 (25H2 Dev Channel)

如何測試:

  1. 請先 解除安裝 目前的版本,然後下載並安裝此實驗版本。
  2. 在工具中啟用 Xbox 全螢幕體驗。
  3. 關鍵步驟:停用尺寸覆寫
    由於此版本仍保留 PhysPanelCS 作為備案,您必須手動停用它,才能驗證新的 Feature ID 是否獨立生效。
    • 一般桌機/筆電使用者:
      開啟「工作排程器」,找到 XFSET-SetPanelDimensions 工作,並將其 「停用」
    • Surface 使用者 (DeviceForm 會被重置者):
      您不能直接停用工作,因為仍需依賴它修復登錄檔。請編輯該工作的「動作」參數,將尺寸 155 87 (7 吋) 修改為 500 300 (約 23 吋螢幕大小),但務必 保留 reg 參數。
      • 範例:set 155 87 reg 改為 set 500 300 reg
  4. 重新啟動電腦。
  5. 驗證: 請回報開機後是否能順利進入 FSE 介面。

重要: 請同時附上位於以下路徑的 Log 檔案:

  • "C:\Program Files\8bit2qubit\Xbox FullScreen Experience Tool\XboxFullScreenExperienceTool.log"
  • "C:\Program Files\8bit2qubit\Xbox FullScreen Experience Tool\XboxFullScreenExperienceTool.log.bak"

(注意:您需要將 .bak 副檔名改為 .txt.log 才能上傳至 GitHub。)
