NSA warns about Windows 10 security issue's

I thought there was a Linux with a windows like OS that people could use instead?

Is it too difficult? Have to know coding?
Does not COMPLETELY integrate?
With significantly less processing used.

Wife bought a new laptop, harddrive failed
I had a friend replace the hard drive and install windows 7-she said it had problems trying to retrofit the OS, & then the hard drive failed again-wondering if now they are built for the OS???

Everyone of my dozens of cousins (& sister) work with software-at least half can or use Linux, as if it is the Jesus software -coming from my ignorance.
