“I have been using Windows 10 since the preview came out.
I am very pleased with how Windows 10 turned out.
The start menu has never been better!
and the OS runs stable.
And the upgrade of a Windows 8 machine went smoothly.
But then a clean one was thrown over it.”
Atoof –
My situation was: a slow PC with Windows 7. It was either a new PC or installing Windows 10. The latter option was the cheapest. No regrets at all. Everything runs smoothly and with the App Store, Windows now easily offers more functionality.
Firos –
Windows links everything to personal information. E.g. unsolicited email to user account, which shocked me. It feels like you’ve lost control over what the OS does and shares. You cannot clearly see what the OS shares about you and with whom, and it is often not possible to opt-out.
Irshan –
Windows 10 Pro includes features for businesses such as network domain joining, Hyper-V virtualization, group policy administration, and BitLocker encryption. That later one may also be of interest to security-conscious home users.
Thushara –
While I couldn’t get used to it with Windows 8, I have no problem with it at all with Windows 10. As expected, the OS is not yet completely bug-free.
