Microsoft isn’t forcing Windows 7 and 8.1 users to upgrade to Windows 10, but they are pushing it on them pretty aggressively. Windows 10 is now automatically downloaded to all Windows 7 and 8.1 machines as a “recommended update” with the Windows Update tool—whether you want it or not.
Microsoft already made a similar push for Windows 10 last fall, but now they are pushing Windows 10 even harder. The change is meant to make the transition to Windows 10 easier for those who still haven’t upgraded, but the automatic download can be frustrating for some users. The download is at least a few gigabytes in size, so if you have a capped data connection, or have no interest in upgrading ever, the automatic download just ends up using data and taking space. Fortunately, we’ve covered the ways you can block the download and save yourself the trouble, or you can always disable automatic Windows updates entirely.
