Device and Application Information

  • OS Build: 10.0.22631.0
  • Architecture: X64
  • Application Version: 11.2401.0.0
  • Region: en-US
  • Dev Version Installed: False

Additional context
As per privacy.sexy:

Microsoft acknowledges that disabling this service does not adversely affect the system's core functionality (link).
Disabling this service enhances your security by reducing your system's vulnerability surface. This service has been historically susceptible to vulnerabilities such as Privilege Escalation vulnerability (link).
Turning off cbdhsvc also helps improve system performance by reducing the number of background processes as cbdhsvc runs automatically in the background (link).
Additionally, it enhances privacy by preventing the storage and sharing of clipboard history with Microsoft servers. Clipboard data often contains sensitive information, including passwords and credit card numbers (link).

Requested Assignment
If possible, I would like to fix this.
