While the 30 days Microsoft gives users to decide whether or not they like Windows 10 are extremely generous, there is a chance that the user may encounter an incompatibility or a significant problem with Windows 10 after the rollback period expires. These folders occupy around 30 gigs of storage space, which is why Windows deletes them as soon as your 30 day rollback period expires, removing your option to downgrade to your previous version of Windows from the Update & security section of Settings. When you upgrade to Windows 10 from an older version of the OS, the version of Windows you upgraded from is stored in hidden folders named Windows.old, $Windows.~BT and $Windows.~WS located in your computer’s root directory.
While almost every Windows user who upgrades to Windows 10 for free likes the finished product that is Windows 10, it is entirely true that Windows 10, for many users, can be plagued with incompatibilities and issues which can cause such users to basically need to downgrade.
Microsoft knows exactly how tough it can be to make peace with change, which is the reason why, on top of offering free Windows 10 upgrades to all licensed Windows 7 and 8.1 users, the company quite generously also provides users who have upgraded to Windows 10 for free with a 30-day rollback period during which they can test Windows 10 out, and downgrade back to Windows 7 or Windows 8.1 (whichever they upgraded from) if they don’t like it.
