The Change Analysis Diagnostic tool scans the computer and displays recent changes to the following areas:
Software programs: The software programs that are listed in the Add or Remove Programs item in Control Panel.
Operating system components: Hotfixes and downloads from Windows Update.
Browser Helper Objects (BHOs): COM components that Internet Explorer loads when it starts. BHOs can intercept browser events, access Internet Explorer controls, create windows, and install add-ins that monitor messages and actions.
Drivers: Kernel-mode device drivers and file system drivers.
ActiveX controls: COM controls that have been downloaded by Internet Explorer or that are used in some Web pages.
Other Auto-Start Extensibility Points (ASEPs): ASEPs let programs start without action from the user. An ASEP may accept one or more ASEP hooks, each of which is associated with a program.
The tool also displays changes to loaded applications and startup objects.
