Spent today having fun with Windows 10 and can report a mixture of good and bad.
My computer is dual-boot Windows 10 and Ubuntu, both on the same SSD. Used 90% of the time for Ubuntu, 10% Windows. The latter is available for compatibility reasons (rare) and because some software doesn't run on Linux – like Fusion360. I prefer Linux because it's far more secure, more reliable, has cleaner software installation/removal, simpler recovery, no DLL problems, and I like the open system ethos. Apple has similar advantages and a wider range of commercial software available than Linux, but it's a closed system and a bit pricey. Don't switch if you believe Windows is nature's only correct way of doing computing!
Anyway, last week, after an update, Windows refused to boot, and more alarmingly, although the GUI recovery options appeared, they all failed to fix the fault. Closer investigation revealed the error to be a corrupt DLL in the boot partition. This small slice of disk is roughly equivalent to the starter motor of a car engine – if it jams solid, you're not going anywhere soon.
As Ubuntu was operational, it was possible to check the entire disk for errors; none found, confirming I was dealing with a Windows fault.
Windows recovery provides a command-line interface to a set of basic tools including those necessary to repair a damaged boot partition and other awkward cases. Unfortunately, these tools didn't work either, and – because Microsoft disregards other operating systems, I ended up with a computer that couldn't boot anything!
Fortunately Linux is good at recovery – including the ability to read Windows files – and I was able to boot the system from a Ubuntu live image and use it to repair the damage done by the failed Windows recovery. Ubuntu working once again, I used it to download a Windows ISO. Copied in a particular way to a USB stick, a computer can boot from it, and – if necessary – reinstall Windows from scratch. Reinstalling is the option of last resort – it deletes all user loaded software, it resets stuff, there's a risk of losing data, and – because Microsoft assumes only it's allowed on any right thinking user's computer – there's a probability installing Windows might trash Ubuntu as well. (Unlike Linux which is nice to Microsoft and copes with both.)
This made a full-backup necessary. If necessary I could reinstall Windows, then Ubuntu, and then all the user programs and data. Worthy but dull.
Some time later, as nothing is ever easy, I discovered that Microsoft's tool used to create a Windows ISO has a bug. This isn't mentioned by Microsoft, and the error message is meaningless, ho hum. The internet saved me: the tool works if it's copied to, and run from, the USB stick.
Booting from the ISO provided the same recovery options as before, except the reinstall options were missing. I got a little depressed.
However, I unplugged all unnecessary devices and tried again. This time the Windows recovery program produced the hoped for 'Windows re-install, save user data' option, and it ran successfully without damaging Ubuntu. Hurrah! I was considerably pleased even though recovery involved 5 reboots, and another round of updates.
Now for the bad news: Windows fans pay attention. Although the reinstall had honoured some of my privacy settings, several others were ignored. That is, the reinstall had opened many doors that I want kept shut. By default Applications and Windows will share information. Also, Cortana was back. This tool is intrusive and I don't want it. (An anti-FUD view here.) Turns out to be even harder and less safe to disable in the latest Windows update. Killing it entirely may crash your computer. Windows is far more inclined to leak data silently than other operating systems, and it's down to you to stop it.
Should users be concerned about privacy? I think so. Previously computer companies made money by selling hardware, programs and operating systems. This revenue stream is drying up. The new way of making big money is by collecting, selling and exploiting information. Your information. Much of what it's used for is benign, like targetted advertising, but information is easily abused. I've no intention of making it easy to collect and dislike systems, websites and programs that accumulate it. Never forget he who sups with the devil should have a long spoon, or that naive people are attracted to liars…
