There is very little information available about this elusive module. Many Windows 10 users actually make fun of this situation, suggesting that Microsoft hasn’t filled in any description on this module simply because it doesn’t actually know what this service does.

Just installed Win 10 v1607. Found a CDPUsersvc in services.msc . It is set to automatic, Also the description fails, it says “failed to read description. error code 15100”.  So I don’t know what the service is used for.  Does someone know what it is ?

After running this command, the Cdpusersvc process will be isolated forcibly and that might be able to fix any problems related to it.


Solution 5 – Create a .bat file to stop the service

If you’re having problems with CDpusersvc error code 15100, one workaround might be to create a .bat file that will close the problematic process for you. To do that, you just need to follow these steps:

  1. Open Notepad.
  2. When Notepad opens, paste the following lines:
  • @ECHO OFF
  • SC QUERY state= all>servicesdump.txt
  • FINDSTR /L /C:”SERVICE_NAME: CDPUserSvc_” servicesdump.txt >CDPservice.txt
  • FOR /F “usebackq tokens=2” %%i IN (CDPservice.txt) DO SET CDPUserSvc=%%i
  • NET Stop “%CDPUserSvc%”
  • SC  Delete “%CDPUserSvc%”
  • DEL CDPservice.txt
  • DEL servicesdump.txt
  1. Now click on File > Save as.
    CDpusersvc has stopped working
  2. Set Save as type to All Files and enter fix.bat in File name field. Now click Save to save changes.

After doing that, you just need to locate the fix.bat file and run it, and the Cdpusersvc service should be stopped. Keep in mind that this is just a workaround, so you’ll need to repeat it if the issue reappears.


Solution 6 – Scan your PC for malware

If you fear that your PC might be infected by malware, we advise you to perform a full system scan with an antivirus software. There are many great antivirus tools on the market, but for best protection, you should consider using BullGuard.


Solution 7 – Perform a System Restore
