通过注册表恢复Windows 7任务栏隐藏标签并合并图标功能

Absolutely, editing the Windows Registry is a solid solution to restore the default taskbar behavior when the "Taskbar buttons" option is grayed out. Here's a clear, step-by-step guide tailored to your issue:

Step 1: Open the Registry Editor #

• Press Win + R to launch the Run dialog.
• Type regedit and hit Enter. If prompted by User Account Control, click Yes to grant access.

Step 2: Navigate to the Target Registry Key #

In the Registry Editor, head to this specific path (you can paste it directly into the address bar at the top to skip manual navigation):

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Step 3: Modify or Create the TaskbarGlomLevel Value #

• Look for a DWORD (32-bit) value named TaskbarGlomLevel in the right-hand pane. If it doesn’t exist, right-click an empty area, select New > DWORD (32-bit) Value, and name it exactly TaskbarGlomLevel.
• Double-click the value to open its properties.
• Set the Value data to match the behavior you want:
  • 0: Always combine, hide labels (this is the default Windows behavior you’re aiming to restore)
  • 1: Combine when taskbar is full
  • 2: Never combine (this is the problematic state you’re currently experiencing)
• Click OK to save the change.

Step 4: Apply the Change Immediately #

To make the registry edit take effect without a full reboot:

• Press Ctrl + Shift + Esc to open Task Manager.
• Locate Windows Explorer in the Processes tab, right-click it, and select Restart.

If you prefer, a full system restart will also work just fine.

Important Notes #

• Always back up the Registry before making changes: Right-click the Advanced key we navigated to, select Export, save the file to a safe location, and you can restore it if anything unexpected happens.
• If the TaskbarGlomLevel value keeps reverting after you set it, it might be locked by a group policy (common in corporate environments). In that case, you’ll need to check with your IT admin to adjust the policy settings.
