That's nonsense. I've been using it for my exact needs which are somewhat above basic, for many years XP through Vista. It has always performed very well, if not perfectly for me. And I almost have always run beta, too.
Number 3, alright, that may be true. To get around this, I use another OS to boot from (safe mode from same OS would work too), delete all the files from the system (in program files and windows\system32), remove the service by hand if the uninstaller that froze did not lol, delete the Windows\Internet Logs folder, and then run a reg clean. Then a new install is possible, if ever needed.
