Problem:

SCCM 2012 R2 CU4
Task sequence deployment run outside maintenance windows when the maintenance windows is set to apply only to task sequences.
When the maintenance windows is set to apply to All deployments, the task sequence deployment run inside maintenance windows as expected.

The maintenance task defined was as:
Name: Maintenance Windows of Collection Coll_A
Time: 10:30am to 06:00am
Date: 20th March 2015
Apply this schedule to: Task Sequences

The task sequence defined was as:
Deployed to Collection Coll_A
Time: Run as soon as possible

The task sequence run at 9:48am on a workstation that is member of Coll_A.
There aren't other maintenances windows on others collections.

Yes, I know this is an old post, but Im trying to clean them up. Did you solve this problem, if so what was the solution?

Since no one has answer this post, I recommend opening  a support case with Microsoft Customer Support Services (CSS) as they can work with you to solve this problem.
