Windows is an operating system designed by Microsoft. The operating system is what allows you to use a computer. Windows comes preloaded on most new personal computers (PCs), which helps to make it the most popular operating system in the world.
Windows makes it possible to complete all types of everyday tasks on your computer. For example, you can use Windows to browse the Internet, check your email, edit digital photos, listen to music, play games, and do much more.
This tutorial is designed to show you the absolute basics of using a Windows computer, including how to use the desktop, how to open different files and applications, and how to move and resize windows. The information in this tutorial will apply to more recent versions of Windows, including the ones mentioned above. However, once you've learned the basics, you may also want to review one of our version-specific Windows tutorials. Just select the version of Windows that's installed on your computer:
While most versions of Windows are relatively similar, Windows 8 works very differently from other versions. However, if you have Windows 8 on your computer, you should now be able to upgrade to Windows 10, which is more similar to earlier versions, including Windows 7. We recommend upgrading your computer to Windows 10 if you can. Review our Windows 10 tutorial to learn how.
However, we'll still point out any major differences between Windows 8 and other versions, which means you'll see some Windows 8-specific information from time to time. If your computer uses Windows 8, you'll want to review both this tutorial and our Windows 8 tutorial to learn more about the differences.

So normally I see host/fqdn when Windows Computers do their Computer Authentication, but in this case it's sending domain\machinename$. This results in a Reject from AD and a failed [Machine Authentication].
domain\machinname$ is only used when the computer is setup with EAP-PEAP and authentication method = "user or computer authentication". In "Computer authentication" auth mode the correct host/machinname.fqdn is used and authentication works correctly.
Hi John,
Not sure if you're still chasing this problem. We just started doing machine authentication for a small building and are running into this problem now today for some individuals. Something that stuck in my mind shortly towards end of my shift - what build number of Windows 10 were you running into - and did it differ from you lab setup - I saw this on Version 1607 [Build 14393] (My recently updated work and test laptop) and Version 1703 [Build 15063] (affected population version ran in to) - and I hope to have the original version I tested this again shortly Version 1511 [Build 10586] - where I didn't have this problem - Enterprise Version Info - -us/windows/release-info.aspx
Almost forgot one more important detail. The machine passes authentication with "host/FQDN" - and then almost immediately fails with "domain\machinename$" - so this could be a separate issue from OPs.
Made some progress (ruled out Windows 10 versions) and happened to find a recent Aruba KB about this behavior - -NAC-Guest-Access-BYOD/Machine-authentication-fails-when-ssid-profile-pushed-via-GPO/ta-p/290978 - not sure what causes it though and why for some clients. Still trying to do more analysis.
Made some further progress. I was wondering if anyone could try replicating the issue I experienced in Windows 10 Version 1703 with an SSID (802.1x - PEAP-MSCHAPv2) deployed via GPO. In previous versions of Windows 10 - the OS will NOT and SHOULD not allow the creation of duplicate SSID Profiles. Feel free to PM if willing to test - I almost disregarded one person as not having the issue - till I realized a sneaky behavior that masked the issue.
In Version 1703 - the OS is allowing two profiles of the same name to be configured (The Original GPO "Added by Company Policy") and then a user-defined one (either through "Add a new network" - or possibly a by-product of an in-place upgrade) - testing this tomorrow. I suspect if one GPO is (User or Computer Authentication) and the other is (Computer Authentication Only or vice-versa) it's causing the client to machine authenticate as "host/FQDN" followed by immediate failure attempt of "Domain\MachineName$" - based on the various authentication methods if I'm been testing.
This is specific to profile set as "User or computer authentication" with native Windows Supplicant on a 802.1x WPA2Enterprise - PEAP-MSCHAPv2 SSID. If a user interactively brings up the Wi-Fi taskbar on the logon screen, selects the corporate ssid, and clicks "Connect" manually - then the laptop will attempt to authentcate as "Domain\MachineName$". If the Wi-Fi is "toggled" or it attempts to automatically connect (connect automatically setting) without user-interaction of the "Connect" button - the laptop will attempt to authenticate as "host\FQDN-MachineName".
If referring to me. I unfortunately was not able to find the solution. I've been meaning to finally sit down and open a ticket with Microsoft concerning this behavior. I had a lengthy discussion on the TechNet forums whom agreed the "samAccountName" is only for legacy purposes. They informed me last year that in their test lab they couldn't reproduce the specific behavior I was reproducing. I'm hoping to get some time once our third engineer returns and open a ticket with Microsoft -> which bore fruit last time concerning the "Duplicate Profile" issue I discovered last year.
tagged specify authentication mode: User or computer authentication, untagged delete credentials, tagged enable single sign on, selected after user logon, maximum delay: 10 seconds, tagged allow dialogs, tagged this network uses separate vlans
We deployed both wired and wireless profiles via GPO, with the same settings. Wired always uses host/fqdn, manual wireless connection at the logon screen always fails because of netbiosname\hostname$ fails to authenticate. Exactly as described above.
Taking another crack at this again at TechNet finally. I'm curious what the difference is between their lab environment, the original posters, and everyone elses is. Since TechNet and OP couldn't reproduce this problem in their environment, but several other folks are.
Microsoft Support confirmed what they saw in the netsh tracing of the samAccountName - and inquired about the "registry modification" that was referenced - although I changed it - reverted back (waiting to hear back from them now). In the meantime, looking back over everything with fresh set of eyes of my authentication failures. In regards to EAP-PEAP-MSCHAPv2 - What does it mean in ClearPass when the challenge computation doesn't have a "username referenced" (is clearpass generating a challenge incorrectly or an error with how client supplied the user-name in the tunnel?) - even though a user was located? Note - a domain was referenced correctly.
It happens only when you manually connect to network at the login screen. However, if single-sing on is enabled before user login, with "User or computer authentication", computer authentication is porcessed successfully immediately when the user attempts logging in.
Hi all... new to Azure AD here, so bear with me a little. We are moving away from a traditional server / domain. We all have Office 365 licenses and by default (I gather) Azure profiles. We are using Windows 10 Pro on our desktops are connected to a server/domain. Our laptops our Windows 10 Home using standard local user accounts.
What I am wanting to do it log into our computers using the Office 365 / Azure profile (we are currently logging into our server/domain). I understand that we can access work or school accounts using settings and connect it there (which we have done), but the computer is still logged in as a domain user (or, on our laptops, as a local user). From what research I have done, it appears that during a fresh install of Windows 10 Pro, one is given the option to set the computer up under an organization. I assume this is where we could achieve what I am wanting, but there doesn't seem to be anyway to do it if the computer is already set up.
I'm just very confused on this. Do I have to have every employee set up a Microsoft account in order for them to be able to login to Windows using their office 365 account? This just seems like a nightmare, as they are two separate things with two credentials to keep up with -- correct? Or, is there a way to do it that I am just not seeing? If I did a fresh install, would I be given the opportunity to set the computer up under an organization?
Some of the benefits of having your Windows 10 devices in your Azure AD is that your users can join the computer to your Azure AD without any extra administrator privileges, assuming you have configured this in your Azure AD. They can also login to the computer without the need of being connected to a specific company network the first time, as long as they have internet connection. You can also manage your Windows 10 devices wherever it may be in the world.
Start the Windows 10 installation as usual.
Choose Set up for an organization.
Enter your your mail address, on the next page you will enter your password.
In this case the administrator has decided that we need to use Windows Hello/Two-Factor Authentication, therefore we will set up a PIN that is used to logon to the computer. Once this is done we will finish the installation and login to Windows using the PIN-code.
