The executable automatically starts the Update Tool to update the Embedded Toolkit.

Here are the steps to install the toolkit update without modifying existing user settings:

1. Launch WindowsEmbedded8Standard-December_2015_Toolkit_Update.msp
2. Select ‘Next’ button
3. Select ‘Repair’ and click ‘Next’ button
4. Select ‘Repair’ button
5. Select ‘Finish’ button after it finishes the installation

1. Toolkit updates must be installed in the order they were released, so the December 2015 update must be installed after the previous updates in the following order:
1. Sep 2013
2. Mar 2014
3. Nov 2015
4. Dec 2015
2. You may not be able to uninstall this update separately. If this happens, you may have to uninstall the whole Toolkit and reinstall the whole Toolkit and updates in the order above.
