In the last 5 years of working with everything new on the market,
including most flavors of nix, I can honestly say that I've had exactly
1 computer that would not start after OS updates were auto-installed -
it was a Ubunto box and it was quicker to reinstall than to try and fix
it.
I may be the "Exception", but I'm the person following the same set of
rules for security that we've had around for decades, and I'm not having
any of the issues that the masses of ignorant people are - maybe it's
because I don't run as root/administrator on my computers.
My recent experience with Windows is limited, but (unfortunately) I still
get called to fix friend's and relatives' computers. My wife's experience
with Vista lasted one and a half days. I then installed XP on her computer
(I made sure the Dell Optiplex we chose had XP drivers). I've had to
rebuild or fix *several* XP computers when they encountered "ransomware."
Just a month ago, my wife got attacked by it again but (fortunately) I had
found and installed RKill with an icon on the desktop -- and it stops the
malware from loading so you can delete it and clean it out.
The worst problem I've encountered with Windows in the last six months
(fortunately very little contact with it now) is that I had to rebuild a
Dell Vista box twice. This computer is owned by a lady (my godmother) in
her late 70s. She has Norton Anti-Virus installed and it automatically
updates itself and automatically scans the computer. The firewall is on.
Automatic Vista updating is turned on. And there is some kind of Windows
"security something or other" installed and automatically updated. She has
never installed a single program on this computer. She has a 260 Gig hard
drive and, besides the operating system and installed applications (it
came with a few programs like Microsoft Office) she has used less than one
Gig of hard drive space. She surfs the web, writes and responds to email,
and writes a few letters in Word. That's it. It runs behind a UVerse
router, which is also supposed to be firewalled. As far as I know she has
never gotten malware or a virus. Her computer has, however, completely
quit working -- twice in the last six months.
The first time it was a typical KSOD (Black screen of death). A black
screen with a white mouse cursor -- that was it. Since the version of
Vista is Dell OEM, and since she still had a support contract with Dell, I
asked them how to fix KSOD. They gave me instructions on how to use the
restore partition. I then tried about ten "fixes" I found on the Internet,
none of which worked. Finally I decided to backup (which required I get
into RegEdit so I could open a "hive" that allowed me to access the disks,
including my USB thumb drive) and reinstall.
A few months later I got called by godmother again. Her computer wasn't
working. Got there and, this time, it was going into a startup loop and
then into a restore screen. It kept coming back with a "registry
corrupted" error. The "fix?" Reinstall. Again, I did a "vista registry
corruption" search on Google, tried about five suggested "fixes" (none of
which worked) and then backed it up and rebuilt it again. Updates took
about six hours on high speed Internet. Fun.
Linux doesn't have this idiot registry file. (And do a Google search to
see how many times it gets corrupted.) The only times Linux has screwed on
me is when I've done something stupid. The Vista machine (mentioned above)
failed to boot the first after one of its own updates. The second time
there was a power failure and Windows shut down unexpectedly.
A Google search shows that these kinds of problems are more common on
Windows machines than are years of solid service. There are exceptions,
but they are *not* the rule.
