This is my thoughts on upgrading from 7 to 10, and my first few days using it. I just want to post this so others can see what it's like.
My first thoughts where "I'm never going to leave 7. I skipped vista and 8, I can skip 10. Hell even try to switch to a Linux Distro." I was not into upgrading for the privacy issues that are being brought up from every single; post, video review, blog posts, etc. and everyone telling you not to upgrade, and saying that you will be giving up for privacy for it being "Free Upgrade". Then I started just searching around and turns out that they where going to implement all the invasive backdoor programs into 8 and 7 anyway.
Then I figured it could switch to a linux Distro (Zorin and Ubuntu to be exact), I tried to see if I could use it as a daily driver and if i could run the programs I need. As always when I try any Distro it never runs smoothly and lags and It just doesn't work out of the box like most belive. I just don't have the time to go through all the hoops to get it running, gaming on it is sometimes a nightmare, and finding drivers for nvidia usually never runs, and I don't want to hear about things run in wine or you could run windows in a virtual box, NO. Until programs can run natively I don't think I'll be moving to Linux.
It only seems that the only thing 10 has negative about it is the privacy issues (which if you follow the tuts on this site about 90% of the problems are solved). Then I thought "If they are doing this to the "Free Upgrade" and 7 and 8, why would it be any different if I went out and bought a retail disk?" So I did the upgrade, got my new key then did a clean install took about 2 hours. I haven't had any problems so far with programs not working, no driver problems. It feels vary clean, fast, and a nice refresh from 7. There are some things I'd change in the UI, but a little reg editing won't fix.
Overall I'd say it was worth the "Free Update".
Edit:
I'd like to include more tutorials to further fix the privacy issues and other stuff;
