If the constant nagging pop-ups on your computer screen weren't tipping you off, Microsoft really wants you to upgrade to Windows 10. Part of the reason is that it doesn't want another Windows XP fiasco where half the world is still using an older version of Windows when Microsoft pulls the plug on security updates.
Another reason is that Windows 10 ties in closely with Microsoft's cloud services, which is the direction the company is headed. The more people it can get using them, the better it will compete against Google, Dropbox and every other company out there. That makes the latest update "glitch" in Windows 7 and 8 seem a little suspicious.
For a while now, Windows 10 has shown up in the Optional section of Windows Update. In fact, we told you how Microsoft was pre-downloading Windows 10 to your computer just to make the upgrade process smoother when you decide to make the jump.
Being in the Optional section, you had to purposely select the Windows 10 upgrade for it to install. However, in this last round of updates, the Windows 10 upgrade option got pre-selected.
