Microsoft's attitude is arrogant at the very least !
Being a very long time user of MS OS's and having been through the OS upgrade process on many previous versions of Windows I have tried to use best practice for making sure my data is always separate from the OS, as well as backed up onto an external HD.
On all previous versions of Windows I have always done a clean install so as to give the new OS the best chance of having fewer issues and this has been the best way in the past of upgrading/migrating to the latest Microsoft OS.
Now I personally do accept that a new Microsoft OS will have issues and usually in a reasonable time they will be resolved if enough people have the same issue as to be honest it is a numbers game and the more people that have the same issue the more important it is to resolve !
The latest release of Windows aka Win 10 is a very different beast than all previous Microsoft OS's, there are many issues outside of the issues of being able to install it successfully and to be honest the one's unable to install it are the lucky one's !
I have this attitude because although of this new digital age of ours has many benefits from a Techie point of view, I have a major stumbling block with being data slurped via Microsoft's Telemetry and because this has been baked in at the OS level then although its supposed to be turned off for Corporate clients I would be extremely worried if I was in charge of the IT dept of any Corporate company that was going to rollout Win 10 in any form within the business !
Also as a home user the idea of being data slurped and this includes keylogging (recording the key strokes of the keyboard) so no password would be secure as MS would have access to this.
Now I know a lot of people will have the attitude what have you got to hide ? Well for one this is a very dangerous situation, because not only does MS have access to any of you passwords (When using Win 10) but also the ability to install/uninstall any software that it feels it wants to. But wait it doesn't end there, they also have to ability to do anything to your PC that they want without your direct intervention. Nay I hear you say, but if they can install Win 10 without direct user confirmation then they can do whatever they want, because of the way that Windows Updates are done.
Remember they wrote the OS and therefor they know exactly how to bypass any confirmations that would normally be required so that they can install whatever supposedly security updates that they feel is necessary for them to remain in control !
I will say that they are different than any other OS supplier (Except true open source) and I put Apple Mac's and iPhones, Googles Android Devices and Microsoft's Win 10 all in the same boat together.
There are all trying to lock users into their ECO system, Apple has been very successful at this and so has Google and now it is Microsoft's turn to try. The thing is Microsoft based PC's were not used like Mac's and are really a completely different beast altogether but MS is try to lump everyone into the same group, for example just because one owns an X86 PC with a MS installed OS it doesn't mean that they automatically have an Xbox, but Win 10 users have this and cannot remove it easily !
Many gamers use different sources for software of games, some use Steam but Microsoft's future is aiming at being the one stop source for any/all software via the MS Store (Which they will charge a commission for of course ) under the pretense that they will validate that no viruses or malware will be in this software when the OS is basically the worst malware you could install in the first place !
As many users have found out with the latest Anniversary Update they cannot now switch off completely Cortana which will use Edge and Bing of course.
Anyway that is enough of a rant, it seems that we have at least 350m stupid people or businesses out there and I am sure many more will be sucked in along with MS BS PR as being the most successful, enjoyable, happy OS they have ever released with no unhappy users whatsoever !
Well for one I said enough was enough and decided to use a more secure and trustworthy OS at least for the time being - Ubuntu.
I would rather go against the flow than just be a lemming and if I am wrong then I am wrong but at least I am not a lemming - And so far it has been a wonderful experience, far better than Win 10 was and from all what Windows users were telling me it was going to be !
