Windows 8 is a great and efficient OS if you disable the stock interface. I don’t know what kind of crack the person who designed the interface at Microsoft was on when they designed it but there is a reason PC sales have been falling like a rock since the release of Windows 8! The stock interface is almost unusable to most people and I find it takes myself much longer to navigate through the system. That being said, the under the hood parts of the OS are stable, reliable, and efficient. It is based on Windows 7 with a few tweaks. I am personally running Windows 8 with a third party patch to make it look just like the Windows 7 interface.
Windows Vista looked basically just like Windows 7. Windows 7 is the “fixed” version of Vista if you want to look at it that way. Vista wasn’t too bad by the end but the damage was done and it did take a pretty powerful computer for it to run decent. Microsoft has also set minimum standards
If it wasn’t possible to “fix” Windows 8, I would probably have put off any purchases until the situation was sorted out or I decided to make the switch to Apple. Windows 8 is optimized around new hardware such as SSDs and Intel i series processors so I did notice a pretty remarkable speed increase when upgrading a Windows 7 computer to 8.
They are releasing Windows “blue” or Windows 8.1 to fix all the issues with stock 8. Maybe this will turn things around for others.
