What if we could run that script silently? What if we could send a package to a user, have them copy it to a USB drive, and then plug it into a computer they bought at their local big-box store? What if our support teams could gather those hashes by simply plugging in external media? It’s effective for testing, but not effective at scale. Running the PowerShell script from a command prompt isn’t overly difficult, but it is time consuming. The script can be run from the full OS or during OOBE by pressing shift+F10 and launching a command prompt. The hash can be uploaded to your tenant by an OEM, your hardware vendor, or by running a script. If we want to use a deployment profile or use Windows Autopilot pre-provisioning mode, a device’s hardware hash must be uploaded ahead of time. While user-driven AutoPilot can be performed without having a record of the device in our environment, having the hash pre-populated is essential in some scenarios. However, if you have ever had to manually collect AutoPilot hashes from a new Windows device, you should understand how cumbersome the process can be. So what? Why would I want to run a script during OOBE? How can this solve any problems I am having?Īt first glance, this may sound like a solution that’s looking for a problem. By combining these two features – running automatically (or nearly automatically) and executing scripts – we can silently launch a PowerShell script that runs from within Windows before a user ever completes the Out-of-box experience. One of the most powerful tasks a provisioning pack can perform is to run scripts. They apply settings to a device that were added to the package when it was created. Provisioning packs can be run almost completely silently during the Windows out-of-box experience. I am going to focus on two specific features of Provisioning Packages. In other words, how can we solve a common problem using the tools that we already have in our environment? This post is about exploring the art of the possible. In fact, it’s not even directly about OS deployment. This post isn’t meant to be a treatise on replacing imaging workloads with provisioning packages. When Windows 10 was first released, ppkg files had a lot of fanfare but never really gained much traction in enterprise environments. They allow us to provision a PC without bare metal re-imaging and require minimal infrastructure. I truly believe that provisioning packages are often overlooked. If you are reading this article because of this post, I hope that I haven’t oversold myself. It feels like a bold claim – especially given the face that Provisioning Packages (which are saved as ppkg files) have been around for a while but don’t really get used in most environments. Hello, and welcome back! If you follow me on Twitter, you may have seen the above tweet before. Wait until you see what I'm working on next.- Sean Bulger March 23, 2022 ![]() Finally, if you want to see a summary of all the changes that you have made to any of the hash values, you can click on the 'edit' button, which opens the properties dialog box.Provisioning packs are one of the most underrated tools in OS deployment. You can also edit the value for the current or previous time of day by clicking on the clock icon. You can then type anything into that column, except for spaces, which will close the row. If you want to change the value for a known hash, you just click the up arrow on the column that shows the current value. ![]() One of the features of HashTab that is especially interesting is that you can actually edit the existing value for a washtub in two different ways. You can find the file properties option from the HashTab context menu, which is nice because you can see at a glance exactly what you are looking at. When you click on one of the files, you get the context menu, which normally just has two choices: right-click to open it, and then select properties. It makes use of an in-depth, in-memory hashtab table to store data about each file on your computer. It doesn't check for missing parts, corruptness, or corrupted changes, because all of these can be found easily. The most important feature of HashTab is it actually checks for known good hashtags against its database. This article is going to tell you what these features are and why they are important. Most of these features are hidden from the user, and the only way they will be found is by doing a deep search for them. What this program does is very similar to other antivirus programs, but it also has some unique features.
