Microsoft last week bolstered its claim that Windows 10 will be its last operating system by extending the OS’s support lifetime to 2026. After the release last week of Windows 10 Anniversary Update — officially known as 1607 using the year and month label the company has adopted — Microsoft refreshed the Windows support lifecycle database to signal a one-year extension to Windows 10 Enterprise.

Enterprise is the only SKU (stock-keeping unit) that comes in a static version that does not change during its lifespan. Dubbed “Long-term Servicing Branch,” or LTSB for short, the version is intended for systems for which stability and longevity trump the latest features and the newest shiny thing.
