When UVK is installed, the default option is Hide inactive services and drivers. Select the desired option and click OK. Or click Cancel to keep the current option. The list will be automatically updated.

If you choose Hide Microsoft services and drivers, the list can take a while to update, because UVK will have to verfy the digital signatures for all the services and drivers files.

Click Stop all non Microsoft services if you want to stop malware that is running as service, if you want to diagnose a conflict or BSOD, or if you just need to free resources. The services files signatures will be verified before stopping the services, to ensure that only Microsoft services are kept running.

Services:

Be very careful when deleting services, specially system services. Don't delete services which corresponding files are signed by Microsoft, unless its a service belonging to a software already uninstalled and the service has been left behind, or other similar cases.

Often, Trojans and other types of malware infect these services, that's why it's very important to verify their files signatures.

Below is a list of services which files must be digitally signed by Microsoft. If they're not, your system is probably infected. This list contains only the services that are usually always running.
