I have an HP DeskJet 6940 printer installed via Ethernet. The client machine is a Core2 Duo E6850 running Vista Ultimate 32-bit, 4GB of RAM. I am trying to optimize this system by reducing un-necessary drivers and services. I did the "bare-bones" install of the HP software however I still noticed some bloat afterwards. Specifically, I am curious about the following services:
hpqcxs08 - C:\Windows\system32\svchost.exe -k hpdevmgmt
Net Driver HPZ12 - C:\Windows\System32\svchost.exe -k HPZ12
Pml Driver HPZ12 - C:\Windows\System32\svchost.exe -k HPZ12
I discovered these via Process Explorer (SysInternals) and they are collectively taking around 30MB of RAM and consuming 3-5% CPU cycles which to me is unacceptable. Does anyone have experience with these, can you tell me what their function is, and which if any I can safely disable/delete?
