After you apply a Windows 10 feature update, how many days are available to roll back to the previous build?

By default, Windows 10 allows users to roll back to the previous build within 10 days of a feature update. This grace period provides an opportunity to revert if the new update causes compatibility issues or unexpected problems. After 10 days, the previous build's files are typically removed to free up disk space, making a direct rollback impossible without a full reinstallation or system image. While this period can be extended using Group Policy or MDM settings, the default is 10 days. Other options like 5, 14, or 30 days are not the default setting for this rollback period.
