Disable mobsync.exe on Windows Vista

What is it?

mobsync.exe belongs to Internet Explorer.  It synchronize offline web pages, and edited offline documents, calendars, and email messages.

Why disable it?

I found it to be CPU consuming and a non-essential, so disabling it was a necessity.

How do I disable it?

1. Disable Offline Files (Control Panel > Offline Files.

2. Open the Registry Editor (Run > regedit) and navigate to the following:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Publishers\{b44aec44-38f4-4b59-8 df3-10306abf19b2}

3. Change the Enabled key from ‘1’ to ‘0’.

4. Reboot.

That’s it!  mobsync.exe should no longer run again on startup.

  1. You can do this the easy and safer way, Its also the correct way

    What is Mobsync and how can i disable it?

    Mobsync is a Microsoft owned tool which enforces group policy for removable mass-storage devices.

    It simply enables applications such as Windows Media Player and Image Import Wizard to transfer and synchronize content using removable mass-storage devices. thus allowing you to plug in a USB, External hard drive or even a wireless media center for PS3 or Xbox Elite.

    Thankfully it is seriously easy to stop this services from auto running on start up

    1. Select ‘Start’ (The ‘Start’ button) and type ‘Services’

    2. From the results shown in the ‘Start’ menu select the option called ‘Services’

    3. Scroll down the page until you locate a service called ‘Portable Device Enumerator Service’

    4. Double click this service

    5. On the ‘General’ tab (You should be on this already) half way down the page, change the ‘Startup Type’ to ‘Manual’

    6. Select ‘Stop’ which is directly underneath the previous option

    7. Now select ‘Apply’

    For those with UAC activated select ‘Continue’ however this should now stop mobsync from running at startup and as you have set this service to run manually it will only be used when you actually sync devices on your PC or Laptop.

    This will NOT effect any other services on you computer.

    So there you have it in a simple nut shell, the actual answer and the actual resolution



  2. Disable the Portable Device Enumerator Service will NOT prevent mobsync.exe to start!
    I’ve disabled this service month ago and still mobsync.exe is showing in the processes tab in Device Manager.
