Windows 10-test version 14352 is back in Windows Update after it was gone without a trace last week for some users.
Version was pushed out of Insiders in the quick test ring on May 26, but technical problems with the version number and deployment meant that not everyone got it downloaded.
Now this problem thus be directed.
Stabile test versions
Our experience is that the last two Fast Ring versions are very stable, and in certain cases much faster and more stable than the RTM version 10586. This is because these versions charging up to the big summer update coming next month.
A little over bug fixes, and new defects (we see no critical) you can see here.
