I really want to upgrade to Windows 10, but have begun seeing stories come out about the new Terms and how they affect your privacy. It looks like the default Windows 10 system puts copies of your data out on the "cloud", gives your passwords out, and targets advertising to you. The main reason I am looking to upgrade is that Bitlocker is not available on Windows 7 Pro, but is on Windows 10 Pro, and Microsoft no longer offers Anytime Upgrades to Windows 7 Ultimate. However, I don't want to give away my privacy for security. The other option is to wait until October to see what the Windows 10 Enterprise version offers, but it may not be available through retail. Are the privacy minded Slashdot readers not going with Windows 10?It's a pretty reasonable thread at Slashdot - meaning nobody accuses Bill Gates of putting puppies in a blender. But the default Windows 10 privacy settings are really, really bad. Basically they're Google snooping on everything that you do, except that they make you pay for the privilege of using their OS.
This is a good article on all the things you need to do to turn this off. It's unclear whether the monthly Windows Update security fixes will reset the privacy settings to the defaults; Windows 10 users will want to check this each month. It's less unclear whether Microsoft will share your usage habits with NSA - of course they will.
Or you can just switch away from Windows. Microsoft is clearly looking for other ways to milk its customer base, and this snoop-o-matic presumably is only the first of many initiatives from Redmond. Here's a balanced video from a couple years back discussing the pros and cons of switching to Linux from Windows. Me, I made the jump a long, long time ago and have never looked back.
No built-in spyware on Linux, and you don't have to keep checking to see if some security fix just stealth changed your settings. If you surf the web, read email and RSS feeds, and do Office app work, Linux will be fine for you. If you game, why don't you have a Playstation?
