If they stick to implementation of that auto update story for Home users, I'll stick with Windows 7 for as long as possible.
My reason/s aren't primarily because of data, but partly - I use Vox Bolt-on (after 6pm) to do my updates manually, so don't need MS screwing me around by auto loading them during the day.
However, I'm more concerned with the screw-up's they make with their security patches from time to time.
As referred to in this article :
How Windows 10 updating will work: The devil's in the details (from 5th May 2015)
http://www.infoworld.com/article/29...-10-updating-will-work-devils-in-details.html
What if there's something terribly wrong with a patch? How long will it take Microsoft to a) identify that there's a problem and b) fix it? Will the fix zap out the bad patch (as we saw with the Silver Bullet patch last December), or do we need to wait for a full rewrite of the bad patch? Microsoft's track record -- especially recently -- does not inspire confidence.
I was screwed around for about 3 months - think it was early'ish last year - with one of those SSL error messages when trying to log into GMail on Chrome .. to the point that I was eventually unable to log on in the browser.
After hunting around, I finally found an obscure post on a forum with a ref. to a KB FIX Microsoft issued for some or other erroneous patch they'd previously issued.
So stuff them - will stay on Windows 7 'til at least the 11th month, and see if they've made any positive changes re the above, in our favour. Remember, they're hoping everyone switches ASAP so they can push these updates when they want ; by staying on Win 7 it'll hopefully send a message to them that they must change their thinking in this regard.
EDIT :
They need to allow Home users the option of going onto that "Slow Ring" they currently have with early adopters testing Win 10 for them, so updates go out after a few weeks. This article above is ambiguous because it mentions that, but doesn't specify if it's for on Business users, or Home (as well ?) .. though the article sub-headings imply for Business.
Anyone know at this early stage whether Home will have the option of that "Slow Ring" ?
