What's Wrong?

Claude Desktop for Windows is writing incorrect data to the Windows registry, preventing it from autorunning at startup. It's creating invalid data in the following location: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run in the Claude entry, it's adding the following data: "\"C:\Users\John Doe\AppData\Local\AnthropicClaude\claude.exe\" --startup" Maybe because there's a space in the account name? If the error is not corrected, not only does Claude not autorun at startup, but worse, it prevents access to any App settings in ALL Windows App!

What Should Happen?

The correct data should be: "C:\Users\John Doe\AppData\Local\AnthropicClaude\claude.exe" --startup

Steps to Reproduce

On Windows, log in to an account that has spaces in the user name (it may still work without spaces in the user name), for example, John Doe. Enable the "Run on startup" option in File -> Settings -> General, if it's already enabled, disable it, then re-enable it, then restart Windows.
