I wanted to mention a bit about Windows 10 before I go back into hibernation (I'm studying for another computer certification and I'm supposed to be updating my website, but I'm taking a small break). First, Windows 10 is a free update for anyone who currently has a copy of Windows 7 or 8.x -- or, more specifically, if you have a license key for either. You can download Windows 10 anytime you want. Here's the official link. Or you can wait for the update, if you've signed up. However ... I recommend you don't install Windows 10, yet. The one persistent problem I've had throughout all the Windows 10 Technical Previews ("betas") and the full release version is that, randomly, things will delete themselves from or "hide" themselves from my desktop. If they're "hidden," I just need to choose a different Theme and *poof* they return, then I can go back to whatever theme I had. When the files delete themselves, they're really deleted. Hey, I even had one of the Technical Previews automatically uninstall Office 365. That wasn't nice, but it shows a precedent for deleting stuff. There's another known issue that causes your computer to just reboot over and over. I have Windows 10 Pro on three machines and Windows 10 Enterprise Trial on two more. I haven't experienced this problem, but I might just be lucky. Or Microsoft is satisfied in just deleting stuff off my Desktop. Or it could be that I completely wiped my hard drives and installed Windows 10 from scratch. I've also been playing with Windows 10 on an older Asus Zenbook. Microsoft tries to install an update to the Touchpad which makes it not work. Unfortunately, Microsoft updates are now mandatory, so I can't stop it from updating. However, it does appear that this particular update has been removed and my Touchpad works again. There's also been a bunch of folks who try to install Windows 10 and they get the very helpful error message, "Something happened." There are a bunch of recommended work-arounds for this, but no real solution. It's happened often enough that social media picked it up a week or so ago. I'll finish with mentioning that I've heard that the Windows 10 automatic updates can break your display driver. Again, this hasn't happened to me on any of my machines -- and my home machine has an Nvidia, ATI, and an Intel (built-in) video cards. Microsoft has made some improvements in the look of Windows 10 over the Preview builds, but I still think it's a tad ugly. I haven't played with voice control with Cortana and I don't and you probably don't have the $450 3D webcam to do facial recognition logins, but I can use a PIN rather than my full password to log in if I use my Microsoft account (like, firstname.lastname@example.org). I don't particularly care about the split screen thing because I use Display Fusion for my (now) four monitors, but I'm glad MS decided to include that feature. I do think there are a couple security holes that most users will miss (download updates from another computer on my network and use trusted contacts' wireless networks), which should keep me in business for awhile -- not to mention that some antivirus software doesn't support Windows 10, yet. I do think that the Start menu is an improvement over 8.1 and that's definitely worth the cost of the upgrade. There's supposed to be a major update to Windows 10 later this year (I've heard October). It might be a good idea to wait for that update before jumping on the 10 bandwagon.
