I found out about this a couple of days ago and have already turned off automatic updates. I set my home system to let me choose the updates I want.
VERY scummy of Microsoft. I called my sister who isn't at all PC savvy and told her that when this happens to her system, she will no longer know how to use her computer. What's more, some of the applications that work for her under Windows 7 will probably break.
Ain't Microsoft wonderful?
Once more, for anyone who isn't following: MICROSOFT HAS CHANGED WINDOWS 10 TO BE AN AUTOMATIC UPDATE FOR WINDOWS 7 and 8 USERS. IF YOU DON'T DISABLE IT, YOU WILL BE RUNNING 10 IN THE NEAR FUTURE.
