G-Tools SupportProfessional PowerPoint Tools for Presentation Designers
By default, G-Tools will automatically check to see if there are any updates each time PowerPoint starts. If you want to disable this behaviour in favour of using the manual update check button in the ribbon, you can do so by adding a new entry to the Windows Registry. Note that editing the Windows Registry can be dangerous and have catastrophic effects on your PC if you’re not familiar with it so only do this if you are comfortable.
Add a new string value as follows:
HKCU\SOFTWARE\VB and VBA Program Settings\G-Tools\Preferences
Value : Auto Check Updates
Data : False
