  1. Disable Receive Window Auto Tuning

Windows Vista includes the Receive Window Auto-Tuning feature which improves performance for programs that receive TCP data over a network. However, this feature is disabled by default for programs that use the Windows HTTP Services (WinHTTP) interface. Jan 20, 2019 Windows 10 have an auto-tuning feature which tries to dynamically adjust the receive buffer size for transmission and latency of the link. In-fact this feature is present in all Modern Operating systems including Windows 10. Aug 05, 2016  Managing Window Auto-Tuning in Windows 10. The first thing you may want to do is check the status of Window Auto-Tuning. If it is turned off for instance, it is likely that it is not the case for the slow downs, but if it is set, it may very well be the culprit.

I am uncertain about the more modern Windows OS like 8.1 and Server 2012. However, auto-tuning did not work correctly in Windows 7 and Server 2008 R2. One of the biggest symptoms was that GUI-based copy/paste between Windows 7 workstations and Server 2008 R2 servers would fail or creep along very slowly (think of copying a file to the company share or your home drive). Disabling auto-tuning, receive-side scaling, and heuristics almost eliminated the issue for me. If your environment consists of these particular operating systems, then you will want to disable auto-tuning, receive side scaling, and heuristics on both the workstations and servers. There is a hotfix but it may be just as easy to either script it or do it manually.

It is an easy fix and won't interrupt production.

EDIT: Has to be done with elevated privileges.

Windows Autopilot is a collection of technologies used to set up and pre-configure new devices, getting them ready for productive use. You can also use Windows Autopilot to reset, repurpose and recover devices. This solution enables an IT department to achieve the above with little to no infrastructure to manage, with a process that's easy and simple.

Windows Autopilot is designed to simplify all parts of the lifecycle of Windows devices, for both IT and end users, from initial deployment through the eventual end of life. Leveraging cloud-based services, it can reduce the overall costs for deploying, managing, and retiring devices by reducing the amount of time that IT needs to spend on these processes and the amount of infrastructure that they need to maintain, while ensuring ease of use for all types of end users. See the following diagram:

When initially deploying new Windows devices, Windows Autopilot leverages the OEM-optimized version of Windows 10 that is preinstalled on the device, saving organizations the effort of having to maintain custom images and drivers for every model of device being used. Instead of re-imaging the device, your existing Windows 10 installation can be transformed into a “business-ready” state, applying settings and policies, installing apps, and even changing the edition of Windows 10 being used (e.g. from Windows 10 Pro to Windows 10 Enterprise) to support advanced features.

Once deployed, Windows 10 devices can be managed by tools such as Microsoft Intune, Windows Update for Business, Microsoft Endpoint Configuration Manager, and other similar tools. Windows Autopilot can also be used to re-purpose a device by leveraging Windows Autopilot Reset to quickly prepare a device for a new user, or in break/fix scenarios to enable a device to quickly be brought back to a business-ready state.

Windows Autopilot enables you to:

  • Automatically join devices to Azure Active Directory (Azure AD) or Active Directory (via Hybrid Azure AD Join). See Introduction to device management in Azure Active Directory for more information about the differences between these two join options.
  • Auto-enroll devices into MDM services, such as Microsoft Intune (Requires an Azure AD Premium subscription for configuration).
  • Restrict the Administrator account creation.
  • Create and auto-assign devices to configuration groups based on a device's profile.
  • Customize OOBE content specific to the organization.

Benefits of Windows Autopilot

Traditionally, IT pros spend a lot of time building and customizing images that will later be deployed to devices. Windows Autopilot introduces a new approach.

$ /usr/libexec/javahome -vOutput after executing above command may be similar with following text, which means there was two versions of JDK installed, 1.8.0121 and 1.7.079. Matching Java Virtual Machines (1):1.8.0121, x8664: 'Java SE 8' /Library/Java/JavaVirtualMachines/jdk1.8.0121.jdk/Contents/Home1.7.079, x8664: 'Java SE 7' /Library/Java/JavaVirtualMachines/jdk1.7.079.jdk/Contents/Home/Library/Java/JavaVirtualMachines/jdk1.8.0121.jdk/Contents/Home2 How to locate JDK installation folderAbove javahome -v command has already told you where JDKs were installed. Uninstall jdk mac os. Tips on how to uninstall JDK or Java SE in Mac OS X.1 How to see JDK versions already installedThe javahome -v command will list all JDKs already installed in your Mac OS. $ cd /Library/Java/JavaVirtualMachines$ lsjdk1.8.0121.jdk jdk1.7.079.jdk3 How to check which JDK version is currently used by Mac OSUsing java -version or javac -version to show the JDK version used by system.

From the user's perspective, it only takes a few simple operations to make their device ready to use.

From the IT pro's perspective, the only interaction required from the end user is to connect to a network and to verify their credentials. Everything beyond that is automated.

Requirements

A supported version of Windows 10 semi-annual channel is required to use Windows Autopilot. Windows 10 Enterprise LTSC 2019 is also supported. See Windows Autopilot requirements for detailed information on software, configuration, network, and licensing requirements.
