I accidently came across this thread as I have the same issue with TouchPoint analytics on HP laptop.
Unfortunately, your solution cannot work, as this is assuming that touchpoint is installed as a program. It is not. It is installed as a Service in the Windows\System32\DriverStore\FileRepository folder. Even using the built in Admin account you cannot delete from the Windows\System32\DriverStore\FileRepository folder. HP does not mention this on their website (when I last looked) that they do this.
You can do the following:
- Disable the Service using services.msc and look for the reference to TouchPointAnalytics in the description. You will need to Stop the service and then change the 'Start Up' type to 'Disabled'. Note: as a service this will automatically reactivate after a period of time (days or weeks) without your knowledge.
- After doing 1. Remove the service via the Registry, it will be located in (Just delete the whole TouchPointAnalytics key, backup the registry first): Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
Warning: if you haven't used the registry before, probably best avoid doing this and stick with 1.
- Advanced...If you have dual boot Linux partition or access to Linux Live Boot disk, you can delete the software package from the Windows\System32\DriverStore\FileRepository folder using Linux.
You should be aware that HP reactivates or reinstalls the analytics software by installing a SoftwareComponent Update (there is no other information provided by them) through Windows Update. So it quietly reactivates without your knowledge. Which I feel is wrong. I personally remove it via the registry and only apply updates to my system when I am present (i.e. not in the background) and check via services.msc to ensure it has not be reinstalled.
The software does not do anything apart from sending data (may or may not include personal information) about your PC to HP, it can affect the Support Assistant, but I can live with that because the Support Assistant isn't very good or helpful (my view).
TouchpointAnalytics (in my own opinion), behaves like Spyware and the fact you cannot remove it (rootkit) without wiping you system, is a bit of a scandal.
