![]() event if your application is not running. Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity. Look at the log file for registry changes. Another advantage could be WMI permanent event subscription:Ī method to monitor the Registry 'at all times', ie. You can use Process Monitor from Microsoft's SysInternals to monitor registry changes. With this, you get all of the monitoring you want, without the terrifying proposition of modifying a running kernel. If you just want to see both user and kernel-mode registry accesses, the best way to do so is via a real-time ETW trace listener. The advantage is that it is possible to monitor the changes in 'real time'. Writing a kernel-mode driver to intercept registry reads/writes is extremely difficult. It also creates a RegEdit registration file (. So using WMI to monitor the Registry is possible, but less then perfect. RegFromApp is a registry monitoring tool that smoothly monitors all the changes in the registry made by Windows or a certain program you selected. But it seems things are not so easy when talking about Group Policies Editor ( gpedit. This thread explains it fine (thanks you, James T). You can overcome this by creating a WMI class to represent the registry key to monitor:ĭefining a Registry Class With QualifiersĪnd use it with _InstanceOperationEvent derived classes. It is supposed that Process Monitor can capture the registry changes made by any program. ![]() You can't use these classes with HKEY_CLASSES_ROOT or HKEY_CURRENT_USER hives. ![]() To do this, you would need to save the registry state before the event and compare it to the state after the event. To do this, click the Filter menu and select Filter. With RegistryTreeChangeEvent and RegistryKe圜hangeEvent there is no way of directly telling which values or keys actually changed. Start Process Monitor and set a filter for the registry key that you want to monitor. The ProcMon combines the capabilities of two legacy Sysinternals utilities at once FileMon and RegMon. This utility allows you to show how processes access files on disk, registry keys, remote resources, etc. There are three WMI event classes concerning registry:īut you need to be aware of these limitations: The Process Monitor (ProcMon) tool is used to track the various processes activity in the Windows operating system.
