Pull request overview
This PR adds a Windows-specific mitigation for the 0x80131515 dependency load failure caused by Mark of the Web (Zone.Identifier ADS) when dependencies are downloaded and later loaded via Windows PowerShell compatibility (-UseWindowsPowerShell).
Changes:
- Detect files under the saved dependency module folder that have an Internet/Restricted Zone.Identifier and run
Unblock-Fileon them (Windows only).

0x80131515 is the result of Windows Mark of the Web (Zone.Identifier) block. During dependency loading, confirm if MotW would block load and unblock if applicable. Resolves issue #1330
