After the Windows 10 November update 1511, 10586 I cannot attach my databases with SSMS. It would just say that it has stopped working as shown below
I checked the error log and so far this is what I've got
2016-01-19 02:35:46.19 spid51 Attempting to load library 'xprepl.dll' into memory. This is an informational message only. No user action is required. 2016-01-19 02:35:46.21 spid51 Using 'xprepl.dll' version '2014.120.2000' to execute extended stored procedure 'xp_repl_encrypt'.

This is an informational message only; no user action is required.
What could be the problem? I've tried googling if this was a common issue but unfortunately there were no similar problems.
I have tried repairing SSMS through the installer.
