I was using windows 7 on my desktop and opted to try Windows 10, so did the upload thing.
It was a mistake.
Windows 7 was fine for my needs frankly. It's also a more traditional and logical set up for me. For example, Windows 10, you need to search for everything and it's a pain in the ass. No longer is there a control panel for example, but if you search for it, you can link to it.
Also, it fucked up my printer configurations and the new adobe is not what I'm used to (it is now internet driven).
Windows 10 also has this weird start button that links you to various social sites, weather, news, sports, etc. For kids in my opinion.
The one thing about Win 10 that drives me crazy is all the little pop ups that slide in from the right of the screen telling me to update this, or download that. I have no idea how to turn it off as it interrupts my work every time and plays this little tone that drives me bannanas.
At the same time, when I bought a new laptop, it came with win 10, so there was no choice. I've suffered a couple of weird problems, mainly with my wireless modem. Just one day, it stopped working, stopped registering the presence of any wireless networks. I took it back to where I bought the laptop and the tech guy there instantly knew what it was. He deleted the drivers for my modem and reinstalled and voila, it worked. According to him, Win 10 has a few bugs like that. No biggie I suppose, but it was a waste of a couple hours.
So my advice would be that if you're using win 7, stick to it. If you're using win 8, well, I'm told that 8 is a pile of shit, so maybe you want to change.
I was win 7 and frankly, it did everything I needed it to do.
