Is there any way to make taskbar icons bigger in Windows 10?

Solution 1:

You can use 7+ Taskbar Tweaker.

1. Right click the title bar to go to Advanced Options
   
2. Under OptionsEx, set the w10_large_icons to 1

Solution 2:

Install StartIsBack++, it has an option to use larger Icons.

Solution 3:

To add clarity to the other answer relating to 7+ Taskbar Tweaker (http://rammichael.com/7-taskbar-tweaker-v4-4), to access the advanced options you will need to right click on the icon in the system tray and select "Advanced Options". Near the bottom of the list is "w10_large_icons". Simply right-click on the 0 beside it and modify it to a 1, apply the change and the icons will be reverted to their proper size. Note that this feature is only available in the beta version of the program at the time of posting.

Solution 4:

Try this:
1.Go Into Settings
2. Click Display
3. Locate the 'Change the size of text, apps and other items:' slider.
4. You can move that up to your liking. Make sure to sign out and sign back in again for the changes to affect everything.
