I thought that Windows 8/10 tiles/Apps may have been nice except:

1)  You have to physically open them to see what they are reporting

2)  When opened, they take up 20-30 % of your desktop view.

3) They weren't made to be displayed on the desktop.

Windows 7 Gadgets are small and packed with very useful Data plus also make certain computer functions much easier. This the main website where I downloaded most of my gadgets that weren't included in the original Windows 7 Gadget package: Windows10Gadgets.pro - Homepage - Free Desktop Sidebar Gadgets for Windows 10/8.1/7. .

My CPU gadget was what alerted me that my CPU Cooler wasn't cooling efficiently as in the pass. Eventually I needed to upgrade the stock CPU Cooler with Cooler Master 212x EVO which now prevents my CPU (FX 8350) from overheating, even when the CPU is at 100% load. My GPU Gadget constantly lets me know the GPU Temperature and whether the GPU fan is on or off.

I have a Gadget for my UPS that lets me know how much wattage my computer is using at any given time.

Generally, as you can see, I am a big fan of Windows 7 Gadgets. I hope you are correct and they bring that feature back once they determine how to make them more secure. But I would think with all the security features of Windows 10 + Windows Defender + Anti-Virus program it will catch any suspicious attempt by hackers even if they use the Gadgets as a doorway.
