So very hard to determine what's the truth these days. I'm sure it makes most folks just not want to bother, read or even listen.
Agree but thats common with Microsoft, they only put out as much information as they think is needed, but they always leave questions open and unanswered for great time period and then they wonder why an OS is pulled appart by missinformed poeple on the web.
They need to get more people that have information about the subject to react immediatly on stuff like this to set things straight and not wait a week to make a tweet about it.
Same goes for quality testing, those poor insiders now should serve as test subjects for potentially broken updates, the issue is that many have the update cycle turned off and that there is no proper testing of a large audience, end of story updates do get forced on customers with Home edition rendering the machine useless.
MS has to consider to turn those forced updates off for mainly that reason, since it is not only pissing of costomers, it is also very bad reputation that they stack over time.
@starkers
No worries you would not be bombarded with spam since the mail app isnt working atm 
When it comes to snooping around MS does snoop since windows7 and those workarounds do exist since that time.
If you have nothing to hide then you should not be worried the only thing to be worried about is, if the so called improvements actually serve you and if one is willing to throw away a perfectly fine 7 or 8 for windows10 free upgrade.
I upgraded both of my machines to 10 and so far im a bit annoyed by it
Not only does the delayed start of desktop apps still exists, there isnt even a option for you to choose if you want a delay, same as in windows8.x, to eliminate the delay one actually has to tweak the registry to put the delay on 0.1 seconds
This was and has been reported multiple times during preview but 0 F´s were given and nothing was done about it.
Considering that Windows10 isnt faster than windows8 in fact its even slower has me thinking if i might return to windows8.1
If i run a "Jafo rig" i dont want to be forced on potato desktop start perfomance.
Some steam games do not work with windows10 atm unless you repair each of them, i´ve ran into problems installing DirectX10 where Windows10 stated that the cab file isnt recognized and has no stamp and is therefore unsave to use. Forcing it by tweaking the services worked though.
I have never seen a OS that needed that much tweaking to work the way you want it to work, a good example is the explorer, it always starts at the quick access menu and I had to pin my computer to it to get instant access or make shortcuts for everything that is important, so I could acess folders and drives by only using the keyboard (quickly.)
Im just glad that i do mainly use the search function to acess all of my progz, otherwise i would go insane using the old Startmenu, for me thats the biggest downgrade since windows8.1, i hate it same as the windows7 menu, unless the 7 menu is skinned nicely for instance by, Mechos by Xiandi, but that only served as eyecandy and isnt available yet for plate 10.
Ohh and Cortana is on the same level as a two year old when it comes to german language, but that may change once the database is filled.
It is pretty good in searching Pr0n on command though atm.
For everyone that has not yet upgraded, i recommend to wait a while till the hard bugs are wiped out.
But that is just my personal opinion atm that may change in the near future once i get a good Performance increase on Games with DX12.
