Safe sites to download better icons than what came with Win 10 upgrade

Hi All !
I'm a transplant from your "Eight Forum" & I'm almost used to the upgrade to Win 10.
What I can't tolerate are the Desktop icons I'm able to find when using the 'Customize' tab.
I learned how to use a PC when it was built to be fun, back in the good old days of XP, when you could change almost everything imaginable, so the cold, drab icons provided in this 'all work-no play' OS aren't enough for me.
Will you please tell me safe sites for me to get new icons, (where I won't get garbage included in the download with the icons ), so I can make the changes I want?
I'd also like to learn how to change the Desktop Font. The only Font settings I could find were to "allow fonts to be installed" & whether or not to "hide fonts depending on language". If there's a way to change the Desktop font & especially a way to eliminate the annoying shadow, please supply very detailed information so I can change that, too.

Thanks in advance for your help.
All the Best,
DogPal

Hi dalchina & brotherboard!
Many thanks for the tips...I really appreciate your help.
Oh, & thanks a bunch for not poking fun at my need to get nicer icons than what's been provided. I'm glad I'm not alone!
Many thanks
