You are trying to use the Default template when creating new projects, but you realize that some basic settings are changed from the original ones, or there is an error message.
 

There is a simple way to reset the Default template. As it gets re-created every time Trados Studio is opened or closed, you should perform the below steps:

1. Close Trados Studio
2. Browse to the templates folder:
   • SDL Trados Studio 2015: C:\Users\%username%\Documents\Studio 2015\Project Templates
   • SDL Trados Studio 2017: C:\Users\%username%\Documents\Studio 2017\Project Templates
   • SDL Trados Studio 2019: C:\Users\%username%\Documents\Studio 2019\Project Templates
   • SDL Trados Studio 2021: C:\Users\%username%\Documents\Studio 2021\Project Templates
3. Delete the file Default.sdltpl
4. Open Trados Studio

You will notice that the file Default.sdltpl was re-created automatically and that it has only 2 KB in size.

NOTE: 
* If you changed the default location, please rename the Default template from there. 
* If you delete the file while Trados Studio is open and then you close the application, the last known version of the file will be re-created and not the original, default one. In order for this procedure to work properly, you need to close Trados Studio before deleting the Default.sdltpl file.

The Default template gets saved and updated just like other templates and any changes made to it may remain for future projects.
