What is the SecuROM™ entry in the registry?

The Windows registry is a directory that stores settings and options for the operating system for Microsoft Windows. It contains information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the PC, etc. As part of SecuROM™, certain license information as well as information used to optimize the authentication of the SecuROM™ disc signature is stored within the registry keys.

The SecuROM™ registry keys can be found in one or both of the following locations:

Additionally the similar keys can be found in the following location:

Example given HKEY_USERS\S-1-5-21-57989841-1220945662-839522115-1003\Software\SecuROM

Please note that the SID is different on each machine.

Due to the registry management of Windows, you have separate HKEY_USERS\"SID" keys for each Windows user account. Depending on how many user accounts the protected application was executed, the SecuROM™ key might be stored in various HKEY_USERS\"SID" keys.

What is it for?

SecuROM™ registry keys are solely used for storage of drive authentication information and license information.

The purpose of the registry keys labelled "!CAUTION! NEVER DELETE OR CHANGE ANY KEY" and/or "License information" is to enable SecuROM™ to perform its Digital Rights Management function properly (license data is stored beneath this key) and prevent users from inadvertently deleting keys and or values stored beneath this key. Other than the license data, there is no code, EXE, DLL, or driver stored in the registry key.

The "WL" registry folder contains drive calibration values and recognition times. This information is used to optimize the authentication of the SecuROM™ disc signature.

It is not recommended to remove any of the registry keys. If the "Keys" or "WL" folders are removed, these values will be rebuilt with further SecuROM™ disc authentications. It is highly recommended to not tamper with the "UserData", " !CAUTION! NEVER DELETE OR CHANGE ANY KEY" or "License Information" registry key folders.

General Information

All information stored is solely used by SecuROM™, as explained in this statement. No other code, EXE, DLL, service, driver or similar is invoked, neither directly nor indirectly, neither via SecuROM™ nor via Windows OS or other applications. It simply does not contain any information related to the execution of additional code, except SecuROM™'s internal Digital Rights Management enforcing functionality.
