Hi there,

1. Spoolsv.exe is the Windows spooler, this is a genuine Windows process, although there are malware versions of this one too.

2. packethsvc.exe is a process installed by Compuserve

3. wmiprvse.exe is a Windows Instrumentation process, also genuine

4. fxssvc.exe is from the Microsoft Fax.

5. userinit.exe is normally also a genuine process

Grtz,
