As you know, the Diagnostic Policy Service enables problem detection, troubleshooting, and resolution for Windows components on your Windows operating system. When you encounter this kind of problem, you will also see the “Access is denied” error message. This occurs when the “MpsSvc” process does not have the permissions needed for the Registry keys. This kind of problem happens when the TrustedInstaller account is missing the permissions for a Registry key and so to fix this issue, you need to take full control and ownership of the Registry keys.

Once you’re done creating a System Restore point, refer to the following instructions to fix the “Windows could not start the Diagnostic Policy Service” error.

Step 2: Type in “Regedit” in the field and tap Enter to open the Registry Editor.
Step 3: After opening the Registry Editor, navigate to this registry path:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDPSParameters
Step 4: After that, look for the “Parameters” registry key and select Permissions.
Step 5: Now select your account under Group or user names.
Step 6: Next, make sure that the “Full Control” and “Read” boxes are both checked, and then click on the Apply and OK buttons to save the changes.
Step 7: Afterwards, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlWDIConfig

Option | Recommended use |

Automatically select unsigned drivers | Useful for testing on computers that are running versions of Windows that do not require signed drivers. |
Automatically select drivers built for older versions of Windows | Useful for testing driver compatibility with newer versions of Windows. |
Automatically select all drivers installed on this computer | Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance. |
Select driver names from a list | In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time. |

The Windows 10 upgrade error is caused by varying factors including a lack of computer space or resources, malware or virus infestation, or a clogged registry on the computer. The error code 0x80070070 will present itself when there is not enough free space on the computer to perform the necessary updates on the computer. Too many apps or programs downloaded onto the computer, too many photos, or too much music may also contribute to the lack of storage space on the computer, thus contributing to the error, and the computer not being able to install the updates to the operating system properly.
It is important to know how much space there is on the computer to start with prior to trying to free up any space. Use the free program on the computer called the Disk Cleanup tool. This will save time and free up some hard drive space while optimizing the computer to work better.
From the Start menu, browse to the Explore option, and then select This PC. Right-click on the C drive, and then select Properties. Select Disk cleanup. From here, select the options that you would like to clear. Make sure that the recycle bin is emptied of any temporary files or any error logs. Once done, select Okay.
