Detecting Wired, Wireless, and VPN Connections using PowerShell

By Johan Arwidmark / September 2, 2019

In a recent customer project we needed to detect whether the clients where connected via Wired, Wireless (WiFi) and/or VPN. This was a decent sized environment, about 50K clients, with hardware models from both HP, Dell, and Lenovo. The existing code I had did not work across all the hardware, so I reached out to […]

You get what you pay for – Using NVMe disks in a lab

By Johan Arwidmark / February 1, 2019

In my personal labs, and in our classroom labs, we’ve been using Samsung NVMe SSD Pro and Evo disks (950/960/070) for many years with good result. But when Amazon announced a dang good deal, moneywise, just before Christmas, on Crucial NVMe SSD’s (the CT1000P1SSD8 – Crucial P1 1TB 3D NAND NVMe PCIe M.2 SSD), I could not stop myself and asked my manager to order 15 of them, so we could upgrade the remaining classroom hosts from 512 GB to 1 TB. Shiny idea, right?

Setup Low Extra Delay Background Transport (LEDBAT) for ConfigMgr

By Johan Arwidmark / July 12, 2018

LEDBAT, or Windows LEDBAT as the Microsoft implementation of it is called, is yet another option to reduce the impact Windows 10, and other software distribution, will have on your network. This feature is currently available on Windows Server, version 1709 or later, and requires Windows 10 v1607 or later on the client side. Hopefully the feature will be backported to Windows Server 2016 too (it’s technically already there, but disabled, and in the need of a bug fix).

Starting with Windows 10 v1607, OEMs like Dell, HP, Lenovo etc. are required to support TPM 2.0 for new machines certified for Windows 10. Exceptions apply for special purpose commercial systems, as well as custom orders, or machines delivered with a custom image from the customer, but anyway.

Windows 10 Servicing Script – Creating the better In-Place upgrade image

By Johan Arwidmark / June 27, 2018

When doing Windows 10 Servicing, meaning going from one Windows 10 version to the next, it makes absolute sense to do that upgrade using an already updated image. In this post you find a script that does exactly that. This image can obviously also be used for the image you use if upgrading from Windows 7 to Windows 10 (for the few orgs that does).
