The only exception is if you’re using a gifted PC from which the SRP has already been removed. If you’re using Windows 10, 8.1 or 7, then you have a hidden System Reserved Partition. The answer to this question is pretty simple. How to Know If You Have a System Reserved Partition Boot files, recovery files, and files related to the native BitLocker encryption system are stored on this partition. Although hidden and taking up a relatively miniscule amount of disk space, this partition houses important files that are fundamental to how Windows operates. This partition is hidden by default, and most users aren’t even aware of its existence. It is automatically created while a clean copy of Windows 10/8.1/7 is being installed. The partition is carved out of the main system drive, which houses the operating system. Versions of Windows prior to Windows 7 do not have this hidden partition. Windows Server 2008 and later also have this partition.
The System Reserved Partition (often abbreviated to SRP) is a hidden partition created on Windows 7 and later.
