I pretty much use Windows for two applications: FamilyTree Maker and FrameMaker. They run well under the new system but there’s a more to the “upgrade” than meets the eye.
There are a whole host of privacy problems, look here, and some annoying general issues which are all over the internet.
Let’s get it clear, I’m not paranoid about sites gathering information about me, I just want them to be open about it.
I have AdBlock installed along with Ghostery in my browser and they take care of most intrusive browsing stuff but Windows 10 has a heap of things that are nothing to do with the web, they just send info about me and my internet usage to Microsoft. worse still, I need to switch these off rather than accept the default install settings.
If you have doubts about this, search Google for “Windows 10 privacy”, I suggest you read those results carefully!
For information: I use BitDefender free edition for antivirus and Malwarebytes for malware protection, those seem to work well together and rarely intrude on my computer use while keeping my computer clear of problems.
These precautions alone don’t stop Windows “phoning home” so I suggest you check the links given above to protect yourself.
