I will NEVER upgrade to Win10
What those figures do NOT tell you is how many were new PC's and how many were upgrades, if you deduct the new machines you are left with a disturbing number of people that have upgraded.
I installed a dual boot of Win10 on my Laptop
What I found was an OS that gave me no tangible benefit to upgrade and a lot of reasons not to.
It is slower to boot, slower to run, shit got moved around for no good reason and no benefit to anyone but Microsoft.
The ONLY benefit was a slightly smaller footprint in disk space which is probably due to the wasted space of WINSXS in older version.
Win10 is nothing more than an advertising and affiliate platform, pretty much the same as Chrome is for Google.
Now the biz version may be less so but still there is no compelling benefit and for a corporation there are all the costs of training, support and management.
I am happy with Win7, anyone can see by installing a fresh install of Win7 that it runs inside 2gb but add all the Windows updates, it then runs like a dog and needs 4gb. This is clearly Microsoft trying to force people to upgrade by messing with registry, (they were caught doing this before), but it is not going to make me shift to Win10
Even if Microsoft stopped providing updates I would stick with Win7, I would just make sure security around it is safer.
If Microsoft forces a move I am at the stage where I would rather shift to Linux (much as I hate it)
If Microsoft want people to upgrade they need to provide compelling benefits, there are none.
Win10 is a polluted brand for me, a bit like Windows Millenium was.
So they need to get the next version to be lean and mean, I suggest they give developers really slow PC's so they are forced to write efficient code.
