"Not the improvement I had hoped..."2.5 starson by radiogeek
Pros: Start menu was partially back
Several great customization features
Cons: When it came to downloading software from the internet, it had a lot of glitches (download would finish, but installation would never start)
Difficult to navigate at times
Ended up having reboot my computer to Factory settings for the downloads
Summary: Overall, somewhat of an improvement, but it needs a lot of work. I can't wait until the real thing comes out in October. So done with 8.1 Preview!
