What is windows 1809?

Windows 10 version 1809, also known as the October 2018 Update, was a major update to the Microsoft Windows 10 operating system released in October 2018. Some of the key features included in this update were revamped search options, a cloud-powered clipboard, a new screenshot tool, and improvements to the dark mode theme. However, the update faced criticism from users due to compatibility issues, data loss, and bugs, which led Microsoft to pause the rollout of the update. After several months of testing and bug fixes, Microsoft resumed the rollout of version 1809 in January 2019.
