Win10 may allow users to downgrade to the original operating system

[Yesky News Channel News] Recently, Microsoft has confirmed that Windows insider users can upgrade the official version of Windows10 RTM from Win10 Preview and freely activate the system. According to foreign media reports, Russia broke the news that WZor announced the update log of Build 10147 on Twitter. This log reflects that Windows 10 will allow users to downgrade directly to their previous operating system.

The table above shows that Windows 10 allows users upgrading from Windows 7/Windows 8/Windows 8.1 to downgrade directly to the original operating system. Previously, after upgrading Windows 10, even if the Windows.old folder was retained, it could not be directly downgraded to the original operating system, and the IIS account would prevent downgrade.
If this feature is retained in the official version, it will provide a "free regret" for all users who are free to upgrade.
It is worth mentioning that, previously, Russia broke the news that WZor has already exposed the Win10 preview version of the B10147 English 64-bit version of the ISO image and language pack download address via Twitter.
