Q: Anniversary Update to 1607 fails This thread is locked from future replies

Downloaded full version using latest Windows Media Creation Tool. 

Updated everything I can think of and can find on my Surface. 

Checked system files with sfc /scannow. 

Update to 1607 fails with error:

0x80070002 - 0x20007 

"The installation failed in the SAFE_OS phase with an error during INSTALL_DRIVERS operation." 

Reverts to 1511 build.  All suggestions welcomed.  I have upgraded three other Win 10 computers today without problems using same downloaded file.



After trying several things, this procedure seems to have worked for me.  Credit to Pieter Wigleven here:

  • Download psexec.exe from Microsoft TechNet Windows Sysinternals to e.g. c:\temp
  • Open an elevated command prompt
  • Execute psexec with the following parameters (try not to copy/paste):
    • C:\Temp\psexec.exe –s –i cmd.exe
  • A command prompt in the system context should launch:

    Execute the following command:

    • rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN

    Close the command prompt(s) and try upgrading again.

Uninstalling ESET Endpoint Antivirus resolved it for me on my SP4.
