Windows Mobile Device Center Compatibility with Windows 10

The answer is in this post, to help you your find the answer. Your Windows 10 computer probably updated to Win10 1709 creators edition. It requires quite a bit of work with no guarantee the next creator's edition will not break it. Look for answers after the date of 09/01/17. Just be aware even after you follow the instructions you may need to reboot both your PC and Device every time you cradle it.

These are the steps I had to perform in order to get all of my devices at my workplace syncing correctly. I hope this is able to help.

1 - PC Settings

a) Open a Notepad and copy paste this into it. When you save it make sure to select All files(*.*) from the drop down menu and that .bat is at the end of your file name.

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

Run the .bat as administrator.

b) Open Settings > Connections > USB to PC and make sure Connect to the Desktop Computer as a USB Mass Storage Device is off. Then make sure Enable Advanced Network Functionality is checked on.

I had the same problem, I updated the computers with Windows 10 and this stopped working Windows Mobile Center. but searching the web a bit I found the WMDC-Helper.exe program at http://www.junipersys.com/Juniper-Systems-Rugged-Handheld-Computers/support/Knowledge-Base/Support-Knowledge-Base-Topics/ Desktop-Connection-ActiveSync-or-Windows-Mobile-Device-Center / WMDC-in-Windows-10 and returned to work the program without problems which was great relief because in the company it is of vital importance the use of it. I use it for my Trimble TSCe TAB for GPS. first --- install WMDC as windows vista SP2 compatibility, then install WMDC-helper as administrator, once done, just restart your PC and enjoy. Thanks to Mario Vega Cervantes for the post.

I have a similar problem.  WMDC will sync files but fails to sync Outlook Contacts & Calendar.  I thought I might try by setting it to transfer all my contacts &  calendar as if it was an initial sync.  All it did was wipe the contacts and calendar from my PDA and then fail.  Total mess up!!
