Incorrect description of the User directory location

### Type of issue

Outdated article

### Description

Under property value, the page says this:

> This path will be different depending on whether the Windows Forms application is deployed using ClickOnce. ClickOnce applications are stored in a per-user application cache in the C:\Documents and Settings\username directory. For more information, see [Accessing Local and Remote Data in ClickOnce Applications](https://learn.microsoft.com/en-us/visualstudio/deployment/accessing-local-and-remote-data-in-clickonce-applications).

The path describes the username directory as existing under "Documents and Settings" which is not the correct location under Windows 10 and beyond.
