Peek at desktop is not enabled by default in Windows 10. However, you can enable it if you prefer. Let’s start.
Right-click the “Show desktop” button in the taskbar, which is beside the action center.
Here are the two options available: Peek at desktop and Show desktop. Click on “Peek at desktop.”
- When the “Peek at desktop” option is ticked, it is on.
- Follow the steps above to revert.
Open the taskbar settings.
Enable the toggle switch beneath “Use Peek to preview the desktop when you move your mouse to the Show desktop button at the end of the taskbar.”
You can find this one between Use small taskbar buttons and Replace Command Prompt with Windows PowerShell in the menu when I right-click the Start button or press Windows key+X.
Note: To revert, disable the toggle switch above.
Before proceeding, I recommend taking a backup of the Registry.
Go to the following: HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > Advanced.
Locate DisablePreviewDesktop and double-click it.
Enter 0 if you want to turn it on and 1 if you want to turn it off in the Value data field.
Hit the OK button.
