If you experience issues with TPS not opening, getting stuck on loading, or running slowly in the main menu - even after uninstalling a Windows antivirus or performing a fresh TPS installation - Windows Defender may be interfering with TPS.

To resolve this, you need to add two separate exclusions for TPS in Windows Defender so it doesn’t block or slow down the software.

Creating a Windows Defender exception for TPS

1. Go to the start menu and type "Virus & threat protection"
   
   
   
   
2. In the window that pops up, scroll down and find "Virus & threat protection", then click on "Manage Settings"
   
   
3. Scroll down in the new page and find "Exclusions", then click on "Add or Remove exclusions".
4. Click "Add an exclusion" followed by "File".
   
   
   
   
5. Go to C:\Program Files\TrackMan Performance Studio and select TrackMan Performance Studio
   
   
   
   
6. Go C:\Program Files\TrackMan Performance Studio\Modules and select TrackMan.Gui.Shell
