You need to explicitely enable the privilege.  The following function should
do the job.  The documentation on CreateProcessAsUser is vague, and I dont
have time to test it.  It appears you need some or all of the following
privileges (all from the ntsecuritycon module): SE_ASSIGNPRIMARYTOKEN_NAME,
SE_INCREASE_QUOTA_NAME TOKEN_DUPLICATE, TOKEN_IMPERSONATE

def AdjustPrivilege(priv, enable = 1):
    # Get the process token.
    flags = TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY
    htoken = win32security.OpenProcessToken(win32api.GetCurrentProcess(),
flags)
    # Get the ID for the privilege.
    id = win32security.LookupPrivilegeValue(None, priv)
    # Now obtain the privilege for this process.
    # Create a list of the privileges to be added.
    if enable:
        newPrivileges = [(id, SE_PRIVILEGE_ENABLED)]
    else:
        newPrivileges = [(id, 0)]
    # and make the adjustment.
    win32security.AdjustTokenPrivileges(htoken, 0, newPrivileges)
