The common turn-around time for ProSeries to fix a problem is about 2.5 weeks.  But when it involves a Windows update, it sometimes takes longer.

But that is AFTER they realize it is a problem.  They might not even know it is a problem yet.  And unfortunately, this forum is not the best place to report problems because the employees that are able to fix things are often not here.  So you may want to call Support to let them know of the problem, and of the 'fix' that you figured out.  Then wait three weeks and hope they fix it.
