Windows 10: Start Menu, minimized programs in the Taskbar are bigger

Hi guys, I recently re-installed Windows 10 Pro 64 bit and I already ran into troubles.
I fixed most of them with DISM & SFC scans, but for some weird reason my Start Menu, minimized programs in the Taskbar are bigger, and the Folders inside Windows Explorer look somehow a tad smaller. When I reboot these problems are gone, until I restart again, they resurface.

I hope this screenshot helps you to visualize what I'm trying to say.
Two programs are open (Chrome & Mail), they're minimized, but their size has increased about 40%.





In the next screenshot my Folder icons look slightly smaller than their original size:





What could be the cause?

Feature suggestion: Add right-click menu

Suggestion: Please add a Windows 7 Jump-List and/or right-click menu to the GPU-Z icon in the Windows taskbar. Possible menus in it would be "Exit" and "About GPU-Z...".
Maybe also "Switch to tab 1/Switch to tab 2/Switch to videocard 1/Switch to videocard 2" too.
Examples of programs that have such menus are ICQ, Skype, AIM.

NOTE: It seems for a right-click menu, Windows 7 is not needed - it works on WinXP and Vista too.
But even a Windows 7 Jump-list may be good enough.
What do you think?

 

How to actually start program minimized in Windows 10?

Steps i tried to make program (for example: Thunderbird) to load on startup, but minimized:

1. Placed shortcut under: C:\Users\Username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
   
2. In a shortcut properties i've checked "minimized"
   

Rebooted windows, it does start, but MAXIMIZED! Can't make it minimized, just like on MacOS i could set it hidden.
