He noted that Microsoft doesn't provide any warnings or alerts to upgraders that they have just 10 days to roll back. That 10-day policy change was noted this week by Supersite Windows writer Richard Hay in this article. Failure to roll back within that time frame means facing the more labor-intensive wipe-and-replace approach in order to restore the OS. However, with the release of Windows 10 version 1607, individuals and organizations now just have 10 days to perform an OS rollback before the Windows 10 version 1607 install becomes fixed. They could reset their PCs back to Windows 7 within the allotted time.
The 30-day policy served as an assurance of sorts that Windows 7 users wouldn't be left high and dry if their Windows 10 upgrade didn't go well. In-place upgrades promised faster upgrades than the old 'wipe-and-replace' approach. The 30-day rollback capability was a feature for individuals and organizations performing in-place Windows 10 upgrades from Windows 7. However, that changed with version 1607, also known as the 'anniversary update,' which Microsoft released on Tuesday. Previously, Windows 10 had a 30-day rollback period to address the concerns of dissatisfied users. Microsoft has changed the time period associated with operating system rollbacks with Windows 10 version 1607, decreasing it to 10 days.
