It's official: Most people who tried Windows 10 ignored our warnings.
Microsoft released some glowing Windows 10 stats on Monday. Already more than 1 million people have registered with Windows Insider to become a Windows 10 tester. Great! More than 200,000 suggestions or complaints have been filed via the Windows feedback app. Awesome! That's what the Technical Preview's for, after all. A full 64 percent of Windows 10 users installed the Preview straight to their hard drive.
Granted, most people previewing Windows 10 in Technical Preview form are likely savvy computer users, but at this stage it's still in a very early state, with bugs and rough edges. While Windows 10 is already more polished than most alpha software, using early pre-release operating systems is an invitation for catastrophe if any hiccups occur. The beauty of virtual machines is that you can just shut down the program and start over if disaster strikes. That's why PCWorld's Windows 10 installation guide recommends giving the operating system a whirl in a VM.
But only a third of all Windows 10 testers listened, it seems.
Maybe most of you aren't afraid to nuke and reinstall Windows 10 repeatedly if need be. Maybe the kind of person enticed by the Windows 10 Technical Preview is the kind of person who has a spare PC or two lying around. Or maybe I'm just bitter after the ISO-less Windows 8.1 Preview refused to update to the full version after its release and left my work laptop borked for months. Either way, the fact that only 36 percent of Windows 10 installations occur in virtual machines made me do a double take.
The precautions you need to take
There's no denying that operating systems run better straight from the metal rather than virtualized, however--at least if you're using a consumer PC. And for all my preaching, after installing the Technical Preview in a VM on my personal machine I did overwrite Windows 8.1 with it on my work laptop. I'm a sucker for punishment, I guess. Fingers crossed it doesn't break again! (Consider this my premature apology to the IT department if it does.)
There are a couple precautionary steps you'll want to take if you install the Windows 10 Technical Preview over your Windows 8.1 installation or on its own hard drive partition, however.
First and foremost, back up your data. Load up an external hard drive, subscribe to Carbonite, whatever you need to do--just do it! You don't want Windows 10 to burp and wipe out crucial files. PCWorld's backup guide and introduction to free backup tools can help if you need it.
