I am using Windows 7 for my PC but seeing my colleges are upgrade to Windows 10, that's making me think I should upgrade tos this version or not? is Windows 10 better than Windows 7?
I would say better, as it is hard to find something that would be better on 7 than on 10. So here's the list:
1.
Boots much faster
2.
Syncs data - if you log in with a Microsoft account, your Windows settings will be synced. Also there is Onedrive available out of box if you want to sync your files.
3.
Has a good browser out of box - Edge performs as good as other top browsers (though it still might get confused if you have huge number of tabs opened for a long time), and unlike Internet explorer. It is also sandboxed by system so potentially offering better security. Of course you can still use whatever you've got used, just you gain one new worthy option.
4.
Windows Store - every Windows 7 app has a potential to do a malicious thing to the system, and nearly every of them at least somewhat slows down the system. All that things goes away with Windows Store. Unfortunately, right now there is more crap there than useful things, but still there is a decent choice of useful apps, and I guess that even if you find just one app that you will use it's still a great addon to your Windows experience.
5.
Virtual desktops
6.
Mail and Calendar available out of box (though fairly basic).
