window install problem
That looks incorrect. the line 
Deno was installed successfully to C:\Users\yadav.deno\bin\deno.exe
Deno was installed successfully to C:\Users\yadav.deno\bin\deno.exe
Should have been 
Deno was installed successfully to C:\Users\yadav\.deno\bin\deno.exe
Deno was installed successfully to C:\Users\yadav\.deno\bin\deno.exe
Note the missing backslash between yadav and ,deno. Check that first path to see if it has a \bin folder in it.
If so something went wrong! Deno may have been added correctly in the path environment variable.
Please check your path environment variable.
in powershell enter $env:Path
It should contain: 
C:\Users\yadav\.deno\bin 
C:\Users\yadav\.deno\bin
If it does, Deno may have been installed accidentally in the folder: 
   C:\Users\yadav.deno\bin
   C:\Users\yadav.deno\bin
rather than where it should be: 
   C:\Users\yadav\.deno\bin
   C:\Users\yadav\.deno\bin
If so, I would report this as a bug.

deno kv watch vs broadcast channel
Many moons ago -- pre KV -- I also used BroadcastChannel for webrtc signaling in Deploy for a multi-user dice game. It worked very well back then. I think post KV it was somehow crippled.

Importing local files (streaming large JSON files)
I've used this in my in-mem DB code. 
// the hundredK.json file contains 100,000 user objects
// [
//    [0,{"id":0,"value":{"id":0,"first":"Tough","last":"Republic","age":55}}],
//    [1,{"id":1,"value":{"id":1,"first":"Impassioned","last":"Stock","age":10}}],
//    ...
// ]
import * as largeJson from './hundredK.json' assert {type: 'json'};
type User = { id: number, first: string, last: string, age: number }
//@ts-ignore
const UserMap: Map<number, User> = new Map(largeJson.default)
console.log(UserMap.get(1))
console.log(UserMap.get(99990))

// To save the contents of the map to a file
Deno.writeTextFileSync("hundredKJson.json", JSON.stringify([...UserMap.entries()]))
// the hundredK.json file contains 100,000 user objects

//    [0,{"id":0,"value":{"id":0,"first":"Tough","last":"Republic","age":55}}],

[react] document is not defined
Try adding the following to the top of that file: 
/// <reference lib="dom" />
/// <reference lib="dom" />
This is how Fresh handles it, and how I write all client code in TS and then auto-esbuild it to a JS bundle.

FYI many linux commands are just executables. In Windows, they are methods of the command processor.

For Windows. You need to execute. echo from a command processor -- "cmd" 
const command = new Deno.Command("cmd", {
   args: ["/c", "echo","hello world"],
   stdin: "piped",
   stdout: "piped"
 }).spawn();
 
 let result = await command.output();
 const textDecoder = new TextDecoder();
 console.log(textDecoder.decode(result.stdout)); 
const command = new Deno.Command("cmd", {

   stdout: "piped"
 }).spawn();
 
 let result = await command.output();
 const textDecoder = new TextDecoder();
 console.log(textDecoder.decode(result.stdout));
