PATH code

hey i was trying to install a bot and was following steps and accidently deleted this thing called path under environmental variables have no clue what it is for but apparently i need it to work the bot any help on how to get the default one back

 

I remember a couple years ago having to setup 'javac' in environmental variables for certain bots to compile that are java. That might be it, I dont have a lot of experience with the current bots tho.
