     Critics say Microsoft Windows 95 must be able to do what the company has said or sales will fall sharply.

This could mean the public would reject future Microsoft products. The public would lose trust in the company. Some people say this will not happen. They say Microsoft sent out several thousand copies of their new product to computer experts to test several months before it was released. Problems that these testers found were

immediately corrected. Microsoft representatives are working to solve all the other problems buyers find when

they try the new system. Computer industry experts say that if there are no major problems Microsoft can

expect to earn about 7 thousand million dollars from Windows 95 in the first two years. The experts say this

could be just a beginning for Microsoft and the whole computer industry. The experts say Windows 95 can

help the user do many different and difficult tasks. They say this means the sale of more powerful computers

and other computer products will increase as people learn about the new Microsoft product. Other companies

say Windows 95 is not a big improvement. The Apple Computer Company says its Mackintosh Operating System has been able to do many of the same things since 1989. For example, it has been able to let users work two

different programs at the same time. The Amega Computer also has offered this for almost ten years. And IBM

says the operating system it developed about 7 years ago is very similar.
