Are you looking for Windows 11 user agents? Surprisingly, they don’t exist and never will. Recently, User Agent strings have started to become less important for browser detection online and some browser developers — notably the Chrome and Firefox development teams — have «frozen» the Windows version number in their user agent strings at «Windows 10». So even as new versions of Windows are released, the user agents for those browsers won’t reflect this and will continue to report Windows 10.

This means that you won’t find user agents (at least for the major browsers) which report «Windows 11». It also means if you are using Windows 11, most websites will still detect you as being on Windows 10.

Use Client Hints to detect Windows 11 instead

Client Hints are an emerging new approach to identifying web browsers, and they do correctly identify Windows 11. Not all browsers send Client Hints yet; so far it’s just Chromium based browsers that do — that includes browsers like Chrome, Opera, Edge, and Yandex.

If you run Chrome on Windows 11, our homepage will correctly detect what browser and operating system you are using by looking at both your user agent and the client hints your browser is sending, and figuring out what you are mostly likely running.

WhatIsMyBrowser.com API detects browsers with User Agents and Client Hints

If you are a web master who needs to correctly detect Windows 11 and other new browsers and platforms on your site; have a look at our API for an easy way to detect it. You don’t need to worry about the new quirks and complexities that Client Hints are introducing, we’ll do the hard work for you.

Experiment with different user agents

You can use our User Agent Parser page to try out different user agent varieties, or to test if your user agent switcher is working properly.

Database of user agents

If you’re interested in our database of many millions of user agents, please check out our API which provides access to our user agent database. You can perform very detailed and specific queries on it to find user agents that match your exact criteria — version numbers, hardware types, platforms and so on.

The Microsoft Windows Update Agent (also referred to as WUA) is an agent program. It works together with the Windows Server Update Services to automatically deliver patches. It’s able to scan your computer and determine what version of Windows you’re running. This allows the update agent to push new updates onto your device, making the process easier.

Windows Update Agent was first introduced for Windows Vista. It replaced the Windows Update web application and the Automatic Updates client. Because it’s a much better solution for updates, Microsoft kept it in every future release.

What is the Windows Update agent?

The Windows Update Agent improves features of the Automatic Updates client. Browsing the Windows Update website was much of a hassle for many users. Not knowing what update you need can lead to loss of time and many errors.

Windows Update Agent can prevent this.

It can automatically select, download and install needed or recommended updates.

Have you ever had your computer unexpectedly crash?

When using the Windows Update Client, you can recover easier and faster. This is possible because the agent uses a feature introduced in Windows Vista. Windows handles its system files better, allowing for easier recovery.

How does Windows Update Agent Work?

The update agent searches and downloads updates from trusted Microsoft sources. This includes:

  • Windows Server Update Services (WSUS) server
  • Microsoft’s update websites
  • Peer to peer distribution (Windows 10)

Once the update agent detects a new update that is missing from your computer, it begins working. You don’t have to spend any time looking for updates and trying to determine which one to install yourself.

You’re able to manage the Windows Update Agent in the following locations:

  • Control Panel
  • Settings app
  • Group Policy
  • Microsoft Intune
  • Windows PowerShell

Windows Update Agent is compatible with these versions of Windows:

  • Windows Vista
  • Windows 7
  • Windows 8
  • Windows 10

How to check what version of Windows Update Agent is installed?

  1. Use APIs on WinHTTP (Windows HTTP Services) and download Wuredist.cab.
  2. With Cryptography Functions, check if the file has a digital signature from Microsoft. If a digital signature can’t be verified, do not continue with this file.
  3. Use File Decompression Interface APIs in order to extract the XML file in Wuredist.cab.
  4. Determine what architecture your computer is using. With the APIs of Microsoft XML Core Services (MSXML), locate the WURedist/StandaloneRedist/architecture node.
  5. Call IWindowsUpdateAgentInfo::GetInfo to determine the current version of Windows Update Agent.

This method is not able to tell you whether or not your Windows Update Agent version is the latest or not. However, identifying your version allows you to do some research and find out if you need to update it or not.

Parts of Windows Update Agent

Microsoft defines five important parts in the Windows Update Agent:

  • Service Availability: This part is what detects, downloads and installs a Windows update. It also handles updates for some other programs.
  • Server Connectivity: This is an API (Application Program Interface). It connects your computer to the locations Microsoft uses for delivering updates. You can see these above.
  • Update Detection: Scans your computer for updates regularly. This allows you to automate the update process, as you don’t have to check for updates yourself.
  • Update Downloads: Downloads available and mandatory updates from safe locations Microsoft uses. Once again, see the list above.
  • Update Installation: Installs the available updates.

Changes to Windows Update Agent in Windows 10

The manual operation of the Windows Update Agent is no longer supported in Windows 10. This is a major change, as all updates get downloaded and installed automatically. What this means is you can no longer select installations and updates yourself.

Windows 10 users have access to peer-to-peer support when updating. Your systems’ bandwidth is used to distribute downloaded updates to other users. You can change this setting to only distribute within a local area network.

What is the Windows Update agent?
Cumulative updates are also included for Windows 10 users. What this means is that the Windows Update Agent is able to pack older updates together. For example, if updates came out in July, August and September, the October update contains all of them.

These cumulative updates end the need to download more than one update. It also spares you from having to restart your computer many times. But, it has a disadvantage. Downloading and installing updates that fix individual problems is no longer possible.

How to Update Windows Update Agent

Before you begin updating, check that your computer has automatic updates.

On Windows 10, search for Windows Update Settings in your search bar on the bottom left of your screen. Open the matching “System settings” result. Select Advanced Options and choose Automatic from the drop-down menu.

If you’re on an older version of Windows, find the classic Control Panel. Select the Windows Update icon and click the Change Settings link on the left. Under the Important Updates section, make sure that you enable automatic updates.

How to Update Windows Update Agent on Windows 10
