Hi donnaroehrig, I'm sorry to see the issues you've had with the product so far, hopefully once we get through this issue, you'll be on the home stretch. When we are decrypting files, we leverage a service that you seem to be looking at called "Dell Encryption Removal Agent". The Various service descriptions indicate various stages of the decrypt. These can be seen within the "Services" control panel.  Here are the statuses: Waiting for Deactivation Dell Encryption is still installed, is still configured, or both. Decryption does not start until Dell Encryption is uninstalled. Initial sweep The Service is making an initial sweep, calculating the number of encrypted files and bytes. The initial sweep occurs one time. Decryption sweep The Service is decrypting files and possibly requesting to decrypt locked files. Decrypt on Reboot (partial) The decryption sweep is complete and some locked files (but not all) are to be decrypted on the next restart. Decrypt on Reboot The decryption sweep is complete and all locked files are to be decrypted on the next restart. All files could not be decrypted The decryption sweep is complete, but all files could not be decrypted. This status means one of the following occurred: Complete The decryption sweep is complete. The Service, the executable, the driver, and the driver executable are all scheduled for deletion on the next restart. Start Menu > Type Services and click on services > Look for Encryption Removal Agent. The area in the red box will have the status of the agent   During this decryption process, we will be quickly processing files, and those that we cannot process (files that may be loaded at system boot time) will attempt to be processed on the next reboot of the device. by default we are limiting this to a small amount of memory to achieve a quick boot process, though this may not decrypt all data that is being immediately accessed. We can increase the amount of memory that we leverage on system reboot to ensure that we decrypt all data as quickly as possible. To increase this amount, you can create this registry key: HKLM\Software\Credant\DecryptAgentDWORD: MaxBytesRebootValue: 0 If you are uncomfortable making this change, our Dell Data Security ProSupport for Software team can assist at any time. Let us know if this does not get you moving in the right direction, and we can definitely work on other options. 
I have been having this problem lately that the decryption process isnt completely decrypting files. Alot of them are browser files (Firefox or Chrome) but there are alot of Windows files as well. I am running 8.17.2 and this one particular endpoint has been decrypting now for 2 days. I am not connected to the internet, logging in as an admin, the decryption service says in the description Decryption Sweep (from what I understand means Decryption sweep - The Service is decrypting files and possibly requesting to decrypt locked files.)   I dont know how to get these to decrypt so I can do what I need to do (cloning hard drive to a new one).  
DDPE not decrypting all files
