A lot of users are jumping on the Windows 10 upgrade bandwagon too early. This operation system has been in development for a while, but upgrading straight after release is not the best option. Best to wait until after everyone else has been installing the operating system and has reported their problems to Microsoft to be fixed. I would not replace my main operating system with this for a long while, best to wait until all driver issues are resolved. I have had Nvidia drivers working with the RTM 240 build, but this may not be the case with the final release. This OS is getting a lot of press, I will not be swayed by this. Sure, I have the RTM, but this is not my main daily use OS. I am just trying this out. The smart thing to do is to stay with your current operating system and possibly try Windows 10 in KVM or VMware Workstation. That way the user can keep their current operating system and try out Windows 10 the safe way. And this allows you to take screenshots of the installation process to post online. There is a big worry online about the data collection abilities of Windows 10.
If Microsoft wanted your data, they could collect it anyway, and the user would not know about it. If you use a browser such as Firefox instead of Microsoft Edge, and other search engines apart from Bing, then you should be a little safer. But Google collect a lot of data about their users, and there is no protest about that. And if you are not a domestic terrorist or a supporter/member of ISIS, then you have nothing to worry about. Just an excuse to bring up INGSOC and 1984. But we do not have two-way telescreens yet, unless you have a Samsung Smart TV… But that is fixed with a firmware update. Still a worrying thing though. Saying that, there are many people with unsecured webcams in their homes that allow any anonymous user to connect to the camera interface and watch them. Just use this Google hack to find these cameras. inurl view index shtml. This will allow you to find countless online web cameras that do not have a password. Then you can play big brother and watch people. This is why more people should be taught about web security.

Give this a read, this explains everything that is collected during the use of Windows 10 Home or Professional. Apparently the Enterprise edition of Windows 10 and the server 10 edition should not have data collection for obvious reasons. If a user could justify the cost of the Enterprise edition, then they would have less to worry about. Just run this in a virtual machine to try it out if you are that worried about this new operating system.
