For the longest time, I could not get audio to work in the Windows 10 preview build.

No verbal access to Cortana, Microsoft’s voice assistant.

Despite trying a number of fixes and workarounds, I couldn’t fix the issue.

Other early Windows 10 users also werebumping into the same problem.

Now I have sound, and now I can converse with Cortana.

Problems for users are expected, and even part of the improvement process.

Since last October, Windows 10 has been slowly building to its broad public debut on July 29.

Based on the latest build,Windows 10looks to me to be in good shape.

But will it pass muster once it gets into the hands of millions of users?

Getting the wrinkles out

Microsoft desperately needsWindows 10to be a hit.

The earlier builds certainly were rough around the edges.

But with the latest builds, the Start menu feels right – quick to navigate and easy to manage.

Those messages no longer appear.

The work isn’t finished just yet.

Who gets Windows 10 when?

That process is expected to take place this week, which is why testing the current build is critical.

Though its official launch date is July 29, Windows 10 will actually berolled out in a phased approach.

Members of the Windows Insider Program will get it first, starting on launch day.

But the work is far from over.

And then even after the initial launch phase, the Windows Insider Program will continue.

Individual testers, like me, may find the current build of Windows 10 stable and ready to go.
