Microsoft Edge's tab previews can be useful. They offer a thumbnail glimpse of the current page when you mouse over a tab. If you are reading this blog post, however, you may find them annoying, especially when the tab preview for the left-most tab obfuscates Edge's forward and back buttons.
Thankfully, there is a way to disable tab previews for Microsoft Edge. You will need to dip your toes into Windows Registry waters but it's a simple tweak.
To get started, click the Start button and type regedit, hit enter to open the Registry Editor, and give it permission to make changes.
In the Registry Editor, navigate to the following folder:
HKEY_CURRENT_USER > SOFTWARE > Classes > Local Settings > Software > Microsoft > Windows > CurrentVersion > AppContainer > Storage > microsoft.microsoftedge_8wekyb3d8bbwe > MicrosoftEdge > TabbedBrowsing
You can navigate through the folder hierarchy in the left panel, but a faster way is use the Edit menu at the top. Go to Edit > Find and for Find What, enter TabbedBrowsing to jump straight to that folder.
Next, right-click on the TabbedBrowsing folder and choose New > DWORD (32-bit) Value. A new item will appear in the right panel with a temporary name of New Value #1. Rename it TabPeekEnabled.
After renaming it, double-click the TabPeekEnabled item and make sure for Value data, that 0 is listed. Click the OK button and you're done.
Restart the Edge browser and tab previews should be a thing of the past.
