Environment Variables And Password Issues

Dear Microsoft Support Team,
Following our previous conversation, I understand my issues require escalated technical support. I'm detailing my concerns below for your specialized assistance.
Issue 1: Disabled Environment Variable Controls
I'm running Windows 11 Home and cannot modify system environment variables through the standard GUI. The "Edit" button remains disabled despite being the sole administrator account on this PC. This has created a critical problem with my Java and Tomcat PATH configurations. Currently, my system is detecting an outdated Java version, and Tomcat executables cannot be located - both due to incorrect PATH settings that I'm unable to modify.
Issue 2: Authentication Method Constraints
I need to transition from my current PIN authentication to a more secure password system. However, the "Password" option in Sign-in settings only permits changes to my existing account password, which is not my intent. The Windows Hello PIN section only allows modifying my existing PIN rather than replacing it with a robust password. This limitation presents significant security concerns for my system.
These issues are hampering my development work and system security. I would appreciate your assistance in resolving these technical constraints.
Thank you for your expertise and support.
