I don't understand the negative comments about Windows 8. I have had a great time with it. I also like that one OS will let me use all apps and programs I want to use. I too use Classic Shell but I also use the Start Screen. I find it very handy as I do Classic Shell.
What I use the most is the Task Bar. This is where I have all most used programs. One click and I'm in a program.
Things run smoothly with Windows 8 and I also think its the most secure OS Microsoft has yet offered.
It starts up quickly and goes directly to the Desktop. I am running Windows 8.1.1 Pro 64 bit. My main programs are Sonar X3 and Vegas Pro 13 with Aftershot Pro 2 and PantShop Pro X5. All are 64 bits and Windows 8 runs them very well indeed.
Having dual monitors I find Windows 8 supports them better then past OSs. Clearly I have good time with Windows 8 and think it is so far the best OS Microsoft has yet produced.
