Windows Active Sync........

.....And Windows Mobile Device Centre. I had a major update on my Windows 10 computer what stops WMDC and your WinCE device syncing. It looks as yet there is no real fix from Microsoft but on one forum i was looking at someone suggested writing this in a txt file

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

Save this as a bat file and run it. Reboot computer and your WMDC should be syncing again. Worked for me
