# Microsoft Update Catalog

So does Microsoft Update Catalog have Drivers that are for my SUBSYS?  The only way to find out is to do a search of **`SUBSYS_08321028`**

{% embed url="<https://www.catalog.update.microsoft.com/Search.aspx?q=SUBSYS_08321028>" %}

This results in quite a number of hits.  For now remember that there are Realtek, Nvidia, and Intel drivers that were matched

**This example should demonstrate that Windows Update does contain some OEM customized Drivers CAN be used by people like Philip Flint**
