Try to resist a while longer. Microsoft is pushing out regular fixes for many bugs they continue to uncover, and it's just not ready for the general public yet.
If you're using Windows 7, there's no compelling reason to install Windows 10. It's still a major change from what you're used to, and while not as horrific as Windows 8/8.1, it's still a Big Unknown. Windows 10 was developed as a response to the masses who just hated Windows 8 and 8.1, with an attempt to make it look and work more like Windows 7. If you're already using Windows 7... why would you "upgrade" to an operating system that's only trying to emulate what you already have?
If you're using Windows 8/8.1 and hate it, waiting a few more months will mostly likely pay off. Unless you enjoy constantly installing urgent fixes, learning how to do things differently, and making sure you have EVERYTHING you don't want to lose backed up two different ways.
Stay tuned - I'll let you know when upgrading to Windows 10 is finally a reasonable option.
Please share with everyone who's asked you about messages pressuring them into letting Windows 10 install.
