While I consider myself a long way from being an absolute master, I think I have more experience with Microsoft Hyper-V Virtual Machines than your average Joe. I have had to convert a few virtual machines If you have an existing Generation 1 virtual machine, converting it to a Generation 2 and, these days, it can be remarkably simple. At least if the computer already has Windows 10 or 11 installed.Continue reading “Gen1 Hyper-V Virtual Machines to Gen2 by converting boot drives from MBR to GPT”
I recently had to troubleshoot an issue where a new Surface Pro 9 for an employee of an existing company. IT staff unboxed the device and began the initial set up, including Windows 11 22H2 Pro. Initially, the machine joined to the domain, but upon reboot, after joining the domain, absolutely nothing would let us log in to the domain. We tried normal users, domain Administrators, and in the end we had to go back to local users to continue troubleshooting.
We didn’t believe there was a problem with the Domain Controller because all of the other computers in the building are behaving fine. Why just this one brand new computer? In the end, we realized it was because Windows 22H2 (Windows 10 or 11) doesn’t like a Linux-based SAMBA Active Directory server.Continue reading “Windows 22H2 repeatedly says “wrong username and password” trying to login Active Directory user”
I sometimes work in an environment that has reasonably tight security requirements. One of those requirements as that a device’s MAC Address / Hardware Address be entered into a table on the router before it can be assigned an IP address.
I recently showed up on site with a brand new in box Surface Pro 9, but I had no idea how to get the MAC Address of the device because I could not log in and open a command prompt. Or so I thought.
I got to the wifi screen telling me to create a connection, then pressed “Control+Alt+Escape” which brings up Task Manager. Although it did not appear on my screen, I suspected it was running behind the overlay locked to the forefront of my screen. I pressed “Alt+Tab” and was able to confirm my suspicion. I then used the keyboard combination of “Alt+F” to open the file menu, pressed Enter knowing that “Run” was highlighted, typed “cmd” and pressed enter to open a Command Prompt window. All of this was happening behind the “Let’s Connect You to a Network” screen, but as veteran of the keyboard era of Windows, all of this was second nature to me.
From there I was able to run the familiar ipconfig /all command, then, with the help of my phone’s camera, I could take a photo of the output of the command prompt and see the MAC Address that I was looking for.
This was convenient enough, but the thought of just being connected to wifi without ever logging in to the machine and then being able to take advantage of this “defaultuser0” account to open a terminal, and then utilize wget to download and execute potential malware before the computer has ever even been set up… fascinating. I’m sure this isn’t “breaking news” to anyone, infact the feature is probably left in, intentionally, for cases just like my original issue! But it does force me to take pause and think of what I can do with this.
People often get a lot of annoying pop ups down by their clocks in Windows 10 and 11, and what they don’t realize is that they have accidentally allowed “notifications” to come from advertising driven websites that are sending them notifications even when they aren’t visiting that website!
In my opinion, the “notification” feature was the worst thing ever added to modern web browsers, but they all have it: Chrome, Edge, and Firefox all include this ability and with more and more browsers being powered by Chrome (Brave, Opera, etc…) this feature doesn’t look like it’s going away anytime soon. So here’s how to disable it!Continue reading “How to disable “notifications” from all major browsers”
