Do you know the thumbnails that appear when you hover over an app in the taskbar? You do not have for them to always appear, and this guide will show you how to disable them.
- Go to the Winaero Tweaker download page and download the app. It's a small file so the download doesn't take that long. When done, open the .zip file and extract the contents of the Downloads folder. From there, double-click the installation file to begin the installation. If you are prompted with a "Windows Protected Your PC" screen, click the link More information .
- Click the Still Run button. Winaero Tweaker is a popular program that has been downloaded countless times – it is 100% safe to use.
- The rest of the installation is very straight forward – for the most part you just click "next" a lot of times. On the last screen, make sure that Run Winaero Tweaker is selected – you can remove the control from Visit Winaero.com for the latest news – and click on Finish  In the navigation pane to the left of the app, look for Desktop and Taskbar and then select Taskbar Thumbnails from that list.
- Select the box Disable thumbnails completely
- Finally click on the Restart Explorer button. This will stop and then restart Explorer.exe, which is a way to "update" the taskbar.
- Now when you hover your mouse over any of the apps in the taskbar, only the small description panel will appear – no more thumbnails.
- Look through the other options in Winaero Tweaker – there are many of them 🙂 You can use it to restore the "old" volume control style in Windows 10 or increase the size of the scroll bar among many other things.
