Microsoft's operating systems Windows Vista, Windows 7 and Windows 8 as well as Microsoft Windows Server starting from Windows Server 2008, use the chip in conjunction with the included disk encryption software named BitLocker. Microsoft has announced that from January 1, 2015 all computers will have to be equipped with a TPM 2.0 module in order to pass the Windows 8.1 hardware certification.[17]

Google includes TPMs in Chromebooks as part of their security model.[23]

Acer, Wipro, Asus, Dell, Inc., Gigabyte Technology, IBM, LG, Fujitsu, HP, Lenovo, MSI, Panasonic, Samsung, Sony, Eurocom Corporation, and Toshiba provide TPM integration on their devices.[citation needed]

In 2006, with the introduction of the first Macintosh models with Intel processors, Apple started to ship Macs with TPMs. Apple never provided an official driver, but there was a port under GPL available.[18] Apple has not shipped a computer with TPM since 2006.
