Intel HD 5500 Problems with Windows Vista

I bought my asus x555lb laptop before windows vista end of life when I install windows vista (most of the intel drivers require previous versions or mod) it installed drivers successfully without TPM (NO NEED FOR THIS) and graphics drivers (Required for AERO and DreamScene) and how can I mod the igdlh64.inf for Intel HD 5500? A Vista-Fan MSFN user told me that is impossible.
