Window 10 build 10565 has a new feature that allows you to preview tabs so you can have one tab open and hover the mouse over another tab to see what is happening in the next tab. The point of the tab preview is so you can check on another tab without having to click on it and change from the current tab you are viewing. It’s another step in the right direction in general computing efficiency.
These tab previews could still be better in the future. Right now, you only get a split second of what is happening in the other tab when you first hover over it; it cannot keep playing a video for example that might be playing in the other tab, though that would be nice to have one day, particularly if you like sports as much as I do et cetera.
What these tabs can do is let you choose how long after you move the cursor away for the tab preview to continue to show. The default settings in Edge is for the tab preview to go away immediately after you move the mouse and this is suitable for most people. But perhaps you may also want to have the tab preview stay for longer than that.
The following tutorial demonstrates how to change the tab preview show/hide delay time in Microsoft Edge.
How to Change Tab Preview Show/Hide Delay Time in Microsoft Edge
You can change the delay time for tab previews in the Registry Editor. Here is how to do that:
1. Open the Registry Editor app.
2. Using the Registry Editor’s left pane, click through to the following keys:
3. With the TabbedBrowsing selected, click on the TabbedBrowsing DWORD on the right side of the same window.
4. In the Value data field, enter in milliseconds how long you want the delay to be. And then click on the OK button in the DWORD dialog to save the changes.
Note: Should you ever want to restore the default time, open the same TabbedBrowsing DWORD and set the value to 0.
In conclusion, that is how to change the tab preview delay time in Windows 10.
