PTchangefilterservice.exe on 2730p

Does anyone know what the PT change filter service is? This is on a new 2730p tablet. This service is a memory hog and I want to know if it can be disabled.

Thanks.

BUMP!

I've got the same windows service churning away on my 6730b. Give us a clue. I know this is part of HP Protect Tools, but is it essential?

Thanks.

Re: PTchangefilterservice.exe on 2730p

Looking through the Registry, it appears to be the "HP ProtectTools Service".

As it keeps crashing on my laptop (an EliteBook 6930p), I've just disabled the service.

If you want to do this too, go to Start > Control Panel > Administrative Tools > Services. Scroll down the list until you find "HP ProtectTools Service" and double click it. On the next dialog, there should be a drop-down list reading "Automatic"; change this to "Disabled" and the service should never restart. If it's running at the time, you'll want to click Stop, as well.

Re: PTchangefilterservice.exe on 2730p

Had the same problem & stopped the service - however, does anyone know exactly what it it? One of the reasons I was reluctant to get an HP notebook (after several Toshibas) was because the software with my plotter, printers, desktops, etc. were all obscene when it came to program size and load. I am wondering if there is more crap on this notebook like this one?

Re: PTchangefilterservice.exe on 2730p

I just rebuilt the 2730p from scratch-Vista Ultimate, all drivers off the Apps and Recovery CD, then SP1, then the applications off the Apps Recovery CD. I then ran all Windows Updates, then the HP Updates. I did not configure Protectools for use.

I left it running overnight, came in this morning and ptchangefilterservice.exe was using 113MB of ram...as it sat there doing nothing.

Reboot-already at 107 MB as I type this.

I have no problems killing the service as long as the functionality or Protectools remains for my clients.

I can't sell these until this is resolved.

Re: PTchangefilterservice.exe on 2730p

This process PTchangefilterservice.exe crashes every couple of hours on my HP 6735b laptop/notebook. I have not configured the HP protect tools. I have re-installed the drivers etc. It still crashes every few hours.

The exception is "System.NullReferenceException"
The source is "PTHostServices"

The stack trace is:
" at HpProtectTools.PTChangeFilter.CChangeFilter.a(Boolean A_0)\r\n at HpProtectTools.PTChangeFilter.CChangeFilter.Finalize()"

The exception data is:
{System.Collections.ListDictionaryInternal}

It looks like a classic .NET coding error, a class is trying to reference or call methods on one of its own objects that are apparently already GC'd from the class's finalizer.

Please fix this HP! Should be a simple bug to locate.

Re: PTchangefilterservice.exe on 2730p

PTchangefilterservice.exe is part of HP protect tools.  If it's hogging RAM, you probably have an old version.  Personally, unless you use parts of Protect tools intentionally, like the credential manager, or use a fingerprint reader for logging in, I'd just uninstall it. (I don't work for HP, this advice is strictly my own).  If you really want to keep it, check and see if there's a newer version you could upgrade to.   The version that came on my 6735b laptop was a memory hog and also put a lot of unnecessary traffic of a type I never determined onto my wireless network, but subsequent versions fixed these bugs.
