Microsoft will retire Windows 10, with support ending on October 14. Users will not receive security patches or feature updates after this date, potentially exposing around 240 million Windows 10 users to vulnerabilities. Devices compatible with Windows 11 can upgrade for free, but many older systems may not meet the requirements. Microsoft offers an option for an additional year of support updates, which can be obtained by paying or by backing up data to Microsoft's servers. A free method to secure Extended Security Updates (ESU) involves enrolling through the Settings menu, requiring users to back up their PC settings to Microsoft’s cloud services. The free backup covers only the first 5GB of storage, and exceeding this limit requires purchasing additional cloud storage. Following the enrollment steps allows users to secure an additional 12 months of protection for their Windows 10 PC.
