window 7

Looked for a desktop discussion, but couldn't find one. My new desktop is slated to arrive tomorrow. Is there a "best" way to make it look like Windows 7. I absolutely loathe Windows 10. I found a step-by-step instruction by digitaltrends.com, but it's 10+ pages. Anybody done this? Any suggestions?

i have installed thikpad power manager in my computer. after restarting system it shows that battery is not installed what can i do
