Microsoft will officially discontinue support for Windows 10 on October 14, 2025. Users are encouraged to upgrade to Windows 11, which has specific hardware requirements including a modern processor, a minimum of 4 GB of RAM, and a TPM 2.0 security chip. To check compatibility, users can use the PC Health Check app. If a device does not meet the requirements, hardware upgrades or firmware adjustments may be necessary. If the BIOS mode is set to Legacy, users must convert the hard drive from MBR to GPT using the command mbr2gpt /convert /allowfullOS. It is recommended to back up data before upgrading. Microsoft is also offering an Extended Security Updates (ESU) option for approximately €27, extending support for an additional year.
