I just watched your Windows 8.1 video and I can tell you aren't sure about Microsoft's Cloud services. I would urge everyone to stay far away from them!
I had my Windows Live ID perma-banned one day after I uploaded documents to SkyDrive. My account was at least 10 years old. The ban also means that I can no longer sign into Xbox Live or GFWL, so I lost access to paid games, but more importantly for me, my save data on GFWL, which is tied to the account I can no longer sign in to.
I did contact Microsoft Support and I had several of their support agents look into it, but they were only able to tell me that I had violated their code of conduct and there's no recourse for that.
So I had a good read of their code of conduct. In a long list of things you may not "upload, post, transmit, transfer, distribute", this was the first:
"nudity of any sort including full or partial human nudity or nudity in non-human forms such as cartoons, fantasy art or manga."
So that's why I got permanently banned. Amongst the files in my SkyDrive folder, I did indeed have a few photos with nudity. I certainly didn't share any of these photos, in fact my Skydrive folder and everything in it was set to private. But really, non-human nudity in fantasy art will get your Microsoft account PERMANENTLY BANNED.
So at the very least, Microsoft is scanning all of their users images looking for things.
I didn't get a single warning from Microsoft, I would have been happy if they just disabled my access to SkyDrive, there was no need to close my entire account.
My advice is simply not to use SkyDrive at all. But if you really want to for Windows 8, just don't upload anything you don't want Microsoft and potentially their friends to see.
