CM_PROB_REGISTRY_TOO_LARGE

Last Updated: 9/12/2016

The registry is too large.

Error Code

49

Display Message (Windows XP and later versions of Windows)

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

Set the environment variable DEVMGR_SHOW_NONPRESENT_DEVICES to 1. This causes Device Manager to display installed devices that are currently not present. Use Device Manager to remove these devices. If the registry is still too large, reinstall Windows.
