The Windows Debugger (WinDbg) for Linux users

The following provides commands for getting started with WinDbg if you've come from a Linux only background and have only used GDB and LLDB.

VMware Fusion and VHD images

Some Windows operating system trials come as virtual hard disk (VHD) images, that state Hyper-V is required to use them. With macOS and VMware Fusion (at the time of writing, VMware Fusion 12.1.2), you can drag the executable files into VMware (the same as with ISO images) and install them normally. No subscriptions are required to obtain access to a DVD or ISO image if you do not have a system that uses Windows as the base operating system.

Microsoft symbols

git clone --bare [email protected]:usi-systems/easytrace.git

	I figured out how to enable USB device mode on my XPS 13 (9350) 🎉

	Though for some ungodly reason, it uses the right-side full USB port. So a crossover cable is required.
