Putty never had good tab support even with all the various work-around and frankensteins people had made to do it. If that situation has changed in the past 5 years, I'm sure I'm not the only one here who would be excited to hear about the details.
putty needs some serious UI love. It doesn't look like the UI has been updated in over 10 years. I use MSYS which comes with mingw and works for my purposes.
It worries me slightly that I can still remember the URL for PuTTY - I'm not even sure I've used Windows once in the last 5 years in a context where I would have needed it!
