Dumprep.exe is a non-essential (according to Microsoft) process that may be in your system startup. It is OK to remove this but obviously it's not done by deleting dumprep.exe (that would be bad).

Instead we follow these steps:

1. Go to the Control Panel.

2. Double-click the System icon.

3. Click the Advanced tab.

4. Next to Startup and Recovery, click the Settings button. (Note: There are three buttons labeled as this - click the one specifically next to Startup and Recovery).

5. Under Write debugging information, click the drop-down menu and select (none).

It looks similar to this:

Click OK after that. You're done here.

Next we have to check to see if this is listed in the System Configuration Utility.

6. Click the Start button.

7. Click Run.

8. Type msconfig in the field and then click OK.

9. From the window that appears, click the Startup tab.

10. Look to see if dumprep 0 -k exists. If it does, it would look like this:

You can safely uncheck this as it is not a vital system process (again, that's according to Microsoft).

Once done you exit the utility.

Why do any of this?

Anything Windows doesn't have to load on boot (especially that stuff that's not required like dumprep.exe) will make it start up faster. Every little bit helps!
