Snagit 13, followed by 13.0.1 has been released recently, after using the new version for a few days I’ve noticed Snagit automatically including the cursor or mouse pointer for every capture, which was not the case the with the prior version Snagit 12 (correct me If I am wrong), If you like me don’t want the captures to include the cursor, you can exclude it permanently for future captures by making a small change to Snagit All-in-One profile, here is how that can be done.

1. Open Snagit capture window
2. You can notice Capture Cursor was enabled by default for All-in-One profile, disable it.
