They NEED to make it an option in Windows 10 as it will be a welcome addition for many, and there are millions of PC's that can run Aero very well. While some don't want it, many do! So being an option would be great!
Aero Glass by Big Muscle may "corrupt" memory and potentially lead to a BSOD system failure. This is usually when using intense applications that use alpha channels, so do NOT run this with Photoshop, Paint.NET, GIMP, and other similar programs unless you are prepared for crashes and problems.
Back up your work and consider creating a system restore point before installing and using Aero Glass.
