As the other poster noted, WinDbg is actually being actively developed. In fact, it even supports JavaScript. https://github.com/Microsoft/WinDbg-Samples https://github.com/Microsoft/WinDbg-Samples https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/debugging-using-windbg-preview https://docs.microsoft.com/en-us/windows-hardware/drivers/de... As for suitability with userland debugging; I use the WinDbg Preview version almost every day to debug userland programs. I rarely use it for kernel/driver debugging. Quite frankly I was surprised how easy it was to pickup given that I was mostly used to Solaris' mdb and the ubiquitous gdb on other *nixes.
