"Last fall, Microsoft announced that individuals who wanted to keep using Windows 10 past its official end-of-support date could do so by opting into the company's Extended Security Update (ESU) program at a cost of $30 per PC. That payment would get users a single year of additional security updates. Today, less than four months before that October 14, 2025, cutoff, Microsoft is announcing additional options for people who can't or don't want to pay that fee."
