15 years ago? You might have just missed it. Event Tracing for Windows gained a lot of functionality in Windows Vista, which some[1] have described as the most forward-looking and instrumental release in Windows history. Vista had a lot of flaws, but it introduced almost everything fundamental to Windows 7 to Windows 10, save perhaps the more recent developments in virtualization and containerization. From differential application-consistent full backups, to transparent full disk encryption, to the use of a TPM to verify boot integrity.
Vista was a massive release, but also much maligned so maybe you didn't miss much leaving when you did. The tooling has certainly gotten a lot better since then, and so has Windows.
Vista's importance in Windows history can't be overstated. It's regarded as a failure in the end but it provided a great baseline for the releases following it. Windows 10 has a much better networking stack, update mechanism, device driver model, GUI etc, all thanks to Vista.

Rather more recently, Windows has gained dtrace support: https://techcommunity.microsoft.com/t5/Windows-Kernel-Intern...
