Slow file upload via httpPOST - Windows 10 Clients only - ASP.Net

I'm having an issue I can replicate with windows 10 for a local intranet file hosting app. The site is only exposed on our internal domain, and specifically while testing, running on IIS on my PC. Site is deployed in ASP.NET, using a simple file upload via a FileUpload control and HTTPPOST.

Issue : Windows 10 CLIENTS take 8+ minutes to upload the same file a windows 7 CLIENT can upload in 40 seconds. The test file is 70mb. Both client PCs are on the same domain. I was able to replicate this on 2 windows 10 clients(slow) and 2 windows 7 clients(fast) both using chrome. Destination is a shared network drive, file is received in both cases

The code is simple, just using a file save as serverside when the post completes, the issue seems to lie in the POST itself being slow. I've included some information from the headers below from chrome. What I noticed is with the windows 10 clients, I'm seeing a request to "Switch Protocols" and then in addition a 302 response, Here are the header details for each below

What are we doing wrong?

Here is the "Switch Protocols" header only seen on windows 10 clients

The reason for the performance degradation is the use of websocket, which should be avoided for file uploads. An older discussion, Large file upload with WebSocket, but seeing your results, still valid.
