OpenProcessToken Function: Accessing Process Tokens in Windows

OpenProcessToken is a Win32 function used to open the access token associated with a process. The function takes two parameters: a handle to the process whose token is to be opened, and a set of flags specifying the desired access rights for the token.

Once the token has been opened, it can be queried or manipulated using other Win32 functions such as GetTokenInformation and SetTokenInformation. Common uses for OpenProcessToken include checking the privileges of a process, adjusting the security settings of a process, or impersonating a user's security context within a process.

OpenProcessToken is typically used by security-related software and utilities, as well as by system administrators and developers who need to perform low-level security operations on Windows systems.
