Want your own Windows 11 21H2 ARM64 ISOs?

By Michael Niehaus on September 14, 2022 • ( 2 Comments )

I was trying out Parallels Desktop 18’s new feature that allows it to automatically download Windows 11 for ARM64 to install a new VM, and wondered how exactly that worked. Fortunately, it […]

Getting rid of Teams (consumer), revisited

By Michael Niehaus on September 8, 2022 • ( 3 Comments )

My previous post on removing the consumer version of Teams from Windows 11 (to avoid confusion when you’re going to install the business version of Teams) had some holes. Rather than edit […]

Send MDM commands without an MDM service using PowerShell

By Michael Niehaus on August 26, 2022 • ( 1 Comment )

Sometimes you run into something completely by accident; other times, it’s more of a building process based on work that you’ve done in the past. In this case, it’s a combination of […]

How many ways are there to manage Autopilot devices and profiles?

By Michael Niehaus on August 24, 2022 • ( 9 Comments )

Working on presentations frequently makes me revisit past stuff. And in this case, that “past stuff” predates my involvement with Windows Autopilot (I started working on it in 2018). Let’s go back […]

M1 Mac virtualization revisited: Parallels Desktop 18 vs. VMware Fusion 22H2 Preview

By Michael Niehaus on August 15, 2022

I probably own more ARM64-based machines than then typical person, and I used those somewhat regularly for testing OS deployment scenarios. Virtual machines are usually more productive for those types of activities, […]

Fun with TPM firmware version numbers

By Michael Niehaus on August 12, 2022 • ( 2 Comments )

I’ve spent a lot of time looking at Autopilot log files, hardware hashes, and TPM-related “stuff.” And it’s always puzzled me why things have to be so difficult. In this case, it’s […]

Connect the dots: Create your own hashes

By Michael Niehaus on August 8, 2022

My previous post was to figure out the format of an Autopilot (OAv3) hash. But there’s more to that intellectual exercise than the exercise itself, because I wanted to be able to […]

Connect the dots: Reverse-engineering an Autopilot hash

By Michael Niehaus on August 2, 2022

I previously posted details on breaking down an Autopilot hash (really, an OAv3 hash as these aren’t Autopilot-specific), leveraging the OA3TOOL.EXE utility in the ADK to convert the hash into a printable […]

Connect the dots: Remediating the Autopilot hardware hash

By Michael Niehaus on August 2, 2022

It’s a common problem: You send a PC off for repair and it comes back with a different hardware component and is no longer recognized as an Autopilot-registered device. In an attempt […]

Connect the dots: From hardware hash to Autopilot profile

By Michael Niehaus on August 1, 2022 • ( 2 Comments )

In my previous blog post about the hardware hash used with Windows Autopilot, as well as in the official documentation, it mentions that the exact algorithm for identifying a machine isn’t documented. […]

Bypassing Windows 11 hardware requirements, revisited

By Michael Niehaus on July 25, 2022

As I stated previously, bypassing the Windows 11 hardware requirements can be done, but that doesn’t mean it’s a good idea. And I stand by that. But based on a couple of […]

Rufus isn’t magic: How it modifies Windows 11 media

By Michael Niehaus on July 25, 2022 • ( 5 Comments )

I keep seeing messages on social media about using Rufus to work around various things in the Windows 11 installation process that people don’t like. But no one ever actually explains what […]

Geeking out with the UEFI boot manager

By Michael Niehaus on June 29, 2022

It seems like every time I need to work with UEFI, it turns into a multi-day affair involving reading spec documents and source code examples. And this time is no exception. The […]

Breaking down the Windows Autopilot hardware hash

By Michael Niehaus on June 3, 2022 • ( 1 Comment )

Lots of you have gone through the effort of gathering the Windows Autopilot hardware hash from a computer (with around 17 million downloads of the Get-WindowsAutopilotInfo script on the PowerShell Gallery), with […]

Requiring a network connection during OOBE

By Michael Niehaus on May 31, 2022 • ( 3 Comments )

When deploying an organization-owned device, you typically want to put “guard rails” in place to make sure the user goes down the right path. (Really, that’s what Windows Autopilot is all about, […]

Product Review: Apcsilmic DOT 1 Mini PC

By Michael Niehaus on May 19, 2022 • ( 3 Comments )

I’ll state this up front: I’m a fan of ARM64-based PCs. They may not always be the best choice for everyone, but there are always scenarios where they make sense (whether running […]

Language pack handling in Windows 11 continues to evolve

By Michael Niehaus on April 27, 2022 • ( 8 Comments )

The later Windows 10 releases were shifting to using Language Experience Packs (LXPs), which had a variety of limitations. So it wasn’t terribly surprising when Windows 11 shifted back to focusing on […]

Customizing the Windows 11 22H2 Start menu layout

By Michael Niehaus on April 27, 2022

When Windows 11 shipped, the Start menu wasn’t particularly flexible. One of the biggest losses was the ability to group apps into folders. With the release of Windows 11 Insider build 22557, […]

Getting rid of Widgets in Windows 11

By Michael Niehaus on April 26, 2022 • ( 3 Comments )

It’s becoming a theme: things get added to Windows, IT pros want to know how to remove them. Maybe it would be better to not include them in the first place and […]

Getting rid of Teams (consumer)

By Michael Niehaus on April 26, 2022 • ( 4 Comments )

I’ve seen all the grumbling about the consumer Teams app (the one with the white “T” icon) being a bit of a pain to remove, which I didn’t understand — it’s just […]
