    Examples of registry operations that can bring up this error are merging, importing, or restoring a file in the registry.

    Many permissions are involved, and it’s possible that (even though you made the backup, for example), you have insufficient permissions to perform the desired operation.

    What do I do when I get the registry data writing error?

    1. Try again in Safe Mode

  • Press the Windows key and click on the Power button to reveal the shutdown options.
  • The next step is to click Restart but to enter the Advanced Troubleshooting Tools utility, hold SHIFT while clicking Restart.
  • Your PC will now restart and take you to the Advanced Troubleshooting Tools utility. Next, click on Troubleshoot to continue.
  • On the following screen, click Advanced options.
  • Now click the Startup Settings (Windows Startup Settings on older Windows versions).
  • Finally, hit Restart and press 4 to Enable Safe Mode.

    • Now, the computer boots with no drivers loaded. Attempt the registry operation once more to see if it still throws the not all data was successfully written to the registry error.

    2. Change the registry key permissions

  • Press the Windows key + R to open the Run dialog box.

    • These steps solve the not all data was successfully written to the registry error by repair upgrading your system. However, this method reverts your computer to a state with no latest updates installed.

    The general solution is to change the ownership of the file to either yourself or the Administrator. However, before doing that, we recommended that you try performing the registry operation again, but in Safe Mode.
