Remove all HP software from Z2 G9's?

[siggii]

Is there a powershell / etc for removing ALL HP software from the Z2 G9?

All my Z2's freeze for about 10 seconds every 15 minutes or so and have gone from annoying to borderline unusable as I (try to) do more on these PC's. I've searched here and there's been a few pointers to power management + HP tools being the cause - and while I've removed everything from the control panel / apps there are still lots of HP processes that seem to start up again despite setting them to Disabled after a while, and again despite setting power management completely off in the BIOS the problem continues.

I'd like a complete uninstallation of anything HP from the PC's while not having to do a complete reinstall, to at least rule the HP software stack out. Imagine shipping enterprise PC's with a flaw as huge as this though...

Best I've been able to do is run a batch file every day (or however often) to stop and disable HP Windows Services. This prevents the freezing every 15 minutes for me. Here's the script:

REM Disable and stop HP Analytics service

net stop "HpTouchpointAnalyticsService"

sc config "HpTouchpointAnalyticsService" start=disabled

REM Disable and stop HP App Helper HSA Service

net stop "HPAppHelperCap"

sc config "HPAppHelperCap" start=disabled

REM Disable and stop HP Diagnostics HSA Service

net stop "HPDiagsCap"

sc config "HPDiagsCap" start=disabled

REM Disable and stop HP DSU LAN/WLAN/WWAN Switching Service

net stop "LanWlanWwanSwitchingServiceDSU"

sc config "LanWlanWwanSwitchingServiceDSU" start=disabled

REM Disable and stop HP DSU Service

net stop "HotKeyServiceDSU"

sc config "HotKeyServiceDSU" start=disabled

REM Disable and stop HP Network HSA Service

net stop "HPNetworkCap"

sc config "HPNetworkCap" start=disabled

REM Disable and stop HP Services Scan

net stop "hpsvcsscan"

sc config "hpsvcsscan" start=disabled

REM Disable and stop HP SFU Service

net stop "SFUService"

sc config "SFUService" start=disabled

REM Disable and stop HP System Info HSA Service

net stop "HPSysInfoCap"

sc config "HPSysInfoCap" start=disabled

You can set Task Scheduler to run it as Administrator and it may work. Works for me anyway.

Thanks - I'll give it a try.

This is such BS tho on the part of HP, pre-installing defective software on our PC's that (and even Wolf is a pile of crap, I've had to remove it from other PC's due to problems it caused) self-activates itself for the apparent sole purposes of collecting metrics, will I have to have a do-over and do a fresh install to get rid of it all?

I was thinking about picking up another Z2 last year but I think I'll buy from Lenovo (incredibly ironic, Chinese brand has less spy-bloatware onboard) next time.

Update: This didn't work for me, but I found a better solution at Remove-HPbloatware.ps1 page on Github. Particularly important to scroll down and locate the Evil Drivers remover addition to this main Powershell. I ran it, and my HP stuff list in Services drastically decreased. Will monitor to see if I still come across problems.

This is an interesting solution. I may try this, although my system's running well enough after finally disabling all the HP services. That said, I agree that the sheer amount of analytics crud pre-installed on this computer as shipped is insulting at best. I expect it on consumer hardware, but people buy these for work. It actually caused productivity-killing bugs that took months to troubleshoot. I can't imagine supporting a bunch of these for my users.

This machine's specs fit my needs at the right price, so I gave HP a chance after years of steering clear for various reasons. As the hardware purchaser for my organization, they've ensured I won't make the same mistake again.

Yeah, it wouldn't be an issue if you could remove it from the apps section as per usual. For a business machine this is absolutly inexcusable - I have definitely bought my last Z.

ARRRRRRGH it's back

I'm probably going to go a clean reinstall in the near future, I've had it with this BS
