How to Fix Code 49

Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit). (Code 49)

Cause:

The system hive has exceeded its maximum size and new devices cannot work until the size is reduced. The system hive is a permanent part of the registry associated with a set of files that contains information related to the configuration of the computer on which the operating system is installed. Configured items include applications, user preferences, devices, and so on. The problem might be specific devices that are no longer attached to the computer but are still listed in the system hive.

Resolution:

Here are some things that you can try to resolve this problem.
