Given what happened with the previous Windows 10 upgrade, some are worried about a repeat with next month’s Creators Update. But Microsoft says it has a plan in place to ensure a seamless rollout. And they’re going to take their time.

“The Creators Update will begin to roll out on April 11,” Microsoft’s John Cable writes in a new post to the Windows Experience blog. “Like with the Anniversary Update we delivered last August, this update for Windows will proceed in phases.”

According to Cable, the plan goes as follows:

Newer devices first. The first phase of the Creators Update rollout will involve newer devices, starting with those that Microsoft has specifically tested with its PC maker partners.

More devices over time. Based on the feedback Microsoft receives during that initial phase, it will start adding additional devices to the rollout matrix over time.

Complete rollout will take several months. For this release, Microsoft is admitting that the rollout will take “several months.” “Update availability may vary by manufacturer, model, country or region, mobile operator or service provider, specific installed software, hardware limitations and other factors such as feedback from customers,” Cable says.

Assuming this goes well, I bet it rolls out more quickly than that. In fact, I will guess they’re shooting for Windows 10’s second anniversary—roughly August 1—for a complete rollout. But that’s just me guessing.
