HP can provide recovery discs for operating systems that are still under license to them; to verify, check the service tag on the computer and enter the serial number in HP's support site. Outside sources may also sell recovery discs; eBay and Amazon.com have listings for these, as of 2015.
There is a charge for providing recovery discs. Given the age of Windows Vista, users may consider upgrading to a newer operating system, such as Windows 7 or Windows 8. Newer version of Windows provide upgrades in security and more up-to-date hardware and software support, according to specifications listed by Microsoft.
