Windows 8 Update

We have succeeded in removing Windows 8 and replacing it with Windows 7. It looks like we will have to move to LINUX. Some companies are making their systems hardware specific so you cannot remove Windows 8 such as Dell & HP. The question we must ask is what is going on. Why is there such an effort to force Windows 8 on everyone? We have not dissected fully Windows 8 to see what is going on behind the scenes. But this effort to force this operating system on people is not realistic and is anti-free market. Why are computer manufacturing companies getting involved? They should only care about selling machines not forcing a particular operating system on anyone. We cannot and will not provide machines to clients with Windows 8 or manufactured by any company that is making the equipment requiring Windows 8. The one thing I have learned over the years, there is always a reason for such activity no matter how much people deny it.
