As of today, the Windows 10 January Build (9926) is available. So,I’m starting the upgrade on my SP2 and will be following up with a detailed post/review of the new build very soon.

Windows 10 January Build is now Available: How to Get it Yourself

If you want to take a look for yourself, you can but be aware that you MIGHT LOSE ALL OF YOUR LOCAL DATA AND/OR DAMAGE YOUR SURFACE. So, only proceed if you are OK with that risk.

If you think I’m exaggerating, take a look at Microsoft’s warning page.

Before You Start: If you’re OK with the risk, and don’t say I didnt warn you, you should make sure you do the following before you start…

Backup all of your data to OneDrive and/or a USB drive
- Don’t forget your browser bookmarks
- Music
- Pictures
- Videos
- Documents
- Etc…
Make sure you create a recovery drive just in case you need to revert back to Windows 8 the hard way
Make a list of the installed applications in case you need to re-install them
- On this note, make sure you have your installation media before starting
Make sure your Surface is plugged in during the entire upgrade

To get the Technical Preview: OK, if you’re really going to go through with this, follow these steps from Microsoft to get the technical preview.

If you haven’t yet signed up for the Windows Insider program, start here.
If you’re currently configured for the Fast or Slow rings, the build is available now.
Just like last time, this new build will come to you automatically via Windows Update, installed during your maintenance window if your PC is plugged in and on or sleeping.
If you don’t want to wait for it to download and install on its own – you can go to PC Settings, Update and recovery, Preview builds and click the Check Now button to go get it now.
Remember, this is a full build, and it will be installed as an in-place upgrade, so you’ll go through those colorful “installing your apps” screens again. This is because your account is being re-provisioned after the upgrade.

The above won’t all make sense unless you’ve already signed up for the Windows Insider program (per the first bullet).
