WIn 10 Anniversary update, unable to disable HP Drive Encryption

[RickBoatright]

Just bought a refurbed EliteDesk 800 35W G2, which came with Win10 64 bit installed. 

After three fresh-install-resets, where I have told the system to throw away all my info and start over, I am unable to get the factory provided Win10 to not install HP Drive encryption, or indeed all the rest of the HP Client Security suite.

As a result, the upgrade to Win10 1607 fails due to the HP Drive Encryption.

HOWEVER     The drive is not encrypted.

When I go into HP Client security suite, and go to drive, I have a bright red notice asking me to please encrypt the drive, and if I go there, the disk IS NOT CHECKED.  

However, If I attempt to uninstall HP drive encryption, the uninstall fails telling me to disable drive encryption in HP Client Security, which I can not seem to do.

Extensive googling has resulted in no fixes for this (all the solved messages seem to apply to earlier versions and Win7.)

There appear to be 3 unanswered threads on this forum about the same thing, but I'm game to try once more. 

Currently I have windows version 10.0.10568 (which is what came on the computer)  

HP Client security is version 8.6.23.46

I have downloaded and installed all updates available through the HP Support assistant, including the Bios update. 

How do I gedt rid of HP Drive Encryption???

After using chat to talk to an HP support person, our concensus was that since the drive was NOT encrypted, we could force the uninstall using Revo Uninstaller. 

The criteria for this decision were: 

1. There was no drive encryption password requested from the BIOS before boot. 
2. In HP Client Security, there was no checkmark next to the C: drive. 

Before uninstalling, I brought up the BIOS setup and disabled TPM.  This eliminated the (_ugly_) HP / Winmark login screen from the  bios prior to boot.  At that point, the computer was booting directly to the normal windows 10 login screen, but HPCS and HPDE still refused to uninstall.  

How we got-er-done.

1. We downloaded and installed a trial version of Revo Uninstaller Pro.  
2. In revo, we chose "Forced Uninstall."  
3. When asked for the program name, we typed "HP Dr" at which point the program found, and popped up the HPDE program in the selection box. 
4. Select HPDE and select "advanced" in the search options.  
5. Tell it to proceed. 
6. The regular HPDE uninstall runs, and like always fails telling us to disable it in HPCS.  We hit ok. 
7. Now, back in Revo, hit SCAN and revo scans the registry and hard disk for "leftovers" of HPDE.  It finds a lot of them, since at no time was any part of the program uninstalled. 
8. Revo displays the results of scanning the registry.  Select all, and press DELETE. 
9. Revo displays the results of scanning for files related to HPDE. Select all and press DELETE.
10. Revo tells you that you will need to re-boot.  Say yes, and re-boot. 

At this point, the computer should boot normally, and you can log in, and there are no traces of HPDE on the system any more. 

Now, run the regular uninstall for HP Client security.  It will run normally.  (I used Revo to uninstall it anyway in order to make sure it didn't leave anything behind.)

Reboot again.

Now HP CS is gone.  

Go to settings, update and tell it to download and install updates.  The Win10 anniversary rollup edition should install no problem.  -- Mine did.  

-- at this point, you're done.

Hi, sorry for interrupting. I got a perfectly same problem and I've gone through your solution. I thought all my hp drive encryption and clint security apps and data had gone. However, after the uninstallation, the drive encryption login still appears, and I keep on failing to upgrade my Win 10 since it still asks me to uninstall the drive encryption. Now I have no idea what is happening with my hp elite x2 :'(

NIGHTMARE.
