Finally got my PC upgraded to Windows 8 after I saw your question about RetroUI and after a bunch of recommendations from our support desk. So then I gave RetroUI a shot - definitely helped the move to Windows 8. I had only used Windows 8 at work, but now I can actually move my parents to Windows 8 (I downgraded their new one back to Windows 7). Retro UI is worth the $5 because it isn't just a start menu like Classic Shell. I've never been one to balk at something that costs less than a pack of smokes, and have always been leery of free software. At least with RetroUI I seem to get support from a real company. If you follow the rabbit hole down, the parent company (Thinix) of the parent company (R&D Industries) has been in business for like 30 years. I'd pay $5 for the features alone - you can't really compare classic shell to RetroUI on feature set unless you ignore everything else RetroUI does - it's like comparing an iPad to Gen 1 Kindle. Would you rather pay for a tablet, or get a Gen 1 Kindle for free?
