Microsoft Office and other permanent apps (or so I thought) are gone!

Hello
I did a reset earlier because I had this proxy problem (did the unchecking of the LAN settings and everything but it keeps rechecking). I tried everything until I got tired with it and decided to do a reset.. also my laptop restarts randomly and I just bought this laptop a month ago so I thought it was no big of a deal since I chose not to delete my personal files kind of reset.
All my apps are gone
The MS Office, the WinRAR thing, windows defender and the likes.
How do I get them?
I bought this laptop (Lenovo) with Windows 10 as the OS, and I tried to go to Microsoft to download but I can't because it's asking me for product key I DON'T KNOW WHAT TO DOOOOOOOO!!
Microsoft costumer service is closed till Monday and I have to finish school stuffs
Please help me. Please please!!!

The messages I've seen, I believe, tell you that programs will be lost. You should have gotten recovery media with your computer to restore, including all the apps it came with. If you paid for Office, you should have a key in your documentation. If you didn't, you only had the trial installed, which can be reinstalled from here.

Oh yeah :'(
Is that a trial too? Is there no way I can recover them? And I need the Win RAR app and the Windows defender What have I done?!!!!

What is this? I saw "ms office key"?

The Office key is the license key you enter to make it the full app suite, not a trial so it won't stop working after a certain amount of time. You can download 7zip if you need a full archiving program. WinRar isn't free, so unless you paid for it, just use 7zip. If you only need to extract .zip files, Windows does that already. Windows Defender is built-in to Windows, so you have it already.

"Office is installing in the background (27%)"
SIR ARE YOU EVEN HUMAN?! <3
