How To Fix Windows 10 Activation Error 0xc004e016?

Reader Question:
“Hi Wally, I’ve been having this issue when updating from Windows 8.1 pro to Windows 10 pro. I’m trying to activate it but it doesn’t work. Its showing the error 0xc004e016. I still have my Windows 8.1 key. Thanks.” – Derek P., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: Many people are updating their computers to Windows 10 since its release. According to Microsoft, over 14 Million devices are started running Windows 10 twenty-four hours after its release.

Like any other product, Windows 10 is not without its faults. Some people seem to be having trouble updating to Windows 10 due to Error 0xc004e016.

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.
