Yes, I was impressed when I first came across it - it’s no longer available from MS, but it was apparently free (in $) so I was happy to find a downloadable installer on the Internet Archive. TBH it’s the best stitching software I’ve used, although it’s looking like xpano will give it a hard run for it’s money if it can handle bigger panoramas - which I’m sure it can once the teething troubles I seem to be getting are sorted. 
Edit:
I just checked what my definition of “quick” actually is - turns out to be just a smidge over 1 minute including the export, for that 21 x 16MP pano above.
