I was looking at upgrading to windows 10 but have decided against it

Personally, I don't really mind that privacy issue (since browsers do it anyway). Rather, I'm more worried about the compatibility issues that may arise for the applications (and the games) I'm running on my laptop. I am extremely hesitant to get Win 10 since I don't have the option to downgrade back to my Win 8.1 since it was already installed when bought. I am still looking forward to upgrading, though I might want to wait for bug fixes (or Windows 10.1.. LOL) to be appear.

I have some friend who tried to upgrade but then they decided to return back to Windows 8. I am not very knowledgeable on programs and I would prefer the one I am already using.

I am not using Windows, but the only complaint about W10 I have heard from friends who have upgraded was about a scanner not working anymore. I have created on Friday a new email address for a friend that had already updated to 10 and I was amazed to see that Windows found all the email server parameters by itself and that I had nothing to do. For me it is a good Windows vintage, certainly a bit buggy, but the bugs will be fixed, and I would not miss the opportunity to upgrade for free. This said, I would never recommend to somebody using an open source OS to abandon it for a commercial OS if privacy is a concern.

I know someone that upgraded their tablet to windows 10 and it crashed the entire tablet. Don't do it yet!

Yes my son also refuses to upgrade with it Marcy. I believe it is very invasive. It is a shame as I am sure it has some fabulous features otherwise.

I just upgraded to Windows 10 a few days ago and I like it A LOT MORE than Windows 8/8.1. The design is better and everything is more user-friendly. I'll have to look into the privacy invasion thing though. I didn't know it was a problem.

It's true that Windows 10 is set up to share a lot of information by default, but those settings can be easily disabled during installation and through the settings menus. What you saw at Best Buy is actually not all that common. My husband works for an electronics retailer and their tech support folks haven't been seeing a lot of people coming in with major complaints about Windows 10. I think the worst one he's said he saw was the customer who purchased a new computer and her copy of Windows 10 said it wasn't authentic. They returned that computer for her, tried another, and it had the same error. The third one worked fine. They're thinking the issue was caused by something that happened on the manufacturer's end, not Microsoft's fault.
