Will this affect Program X

It CAN (See: What's the Catch), BUT if you need a mainstream gaming app or service excluded, I have options to skip disabling for (* = beta):

• AMD ReLive
• BattlEye
• Chrome
• Corsair iCUE
• Discord
• EasyAntiCheat
• Epic Games Launcher
• Firefox
• Internet Explorer
• Microsoft Mouse & Keyboard
• Microsoft PowerToys
• Microsoft Edge (new)
• Nvidia ShadowPlay*
• OBS
• Oculus VR
• Parsec
• Steam
• SteamVR
• StreamLabs OBS
• VIVEPort*
• VMix
• Wirecast
• Windows Game DVR*
• Windows Mixed Reality*
• Xbox Live
• XSplit

Just select an existing exclusion option(s) from Exclusions menu before selecting Freeze System option. Additionally, you can define your own exclusions, check out the ExampleCustomExclusion.def file under the latest release. If you need help with this feel free to reach out to me and include the export.csv file generated using File -> Export. I hope to have a Discord and Subreddit up soon for users to share their own Exclusion Definitions.
