Cannot Update to Windows 10

Rodeo211 · Jul 31, 2015

I am looking for help with what seems to be a complex problem.

I cannot update Windows 7 Ultimate to Windows 10

Computer has tried multiple times with:
Error Code:80240020

I have tried to use an image on a USB which worked on another system

EDIT: SFC: No file corruptions (after running SFCFix.exe)

Dism gives these errors:

Code:

C:\Windows\system32>Dism /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Image Version: 6.1.7601.18489


Error: 87

The restorehealth option is not recognized in this context.
For more information, refer to the help.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

OR

Code:

C:\Windows\system32>Dism /Online /Cleanup-Image /StartComponentCleanup

Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Image Version: 6.1.7601.18489


Error: 87

The startcomponentcleanup option is not recognized in this context.
For more information, refer to the help.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

Has my windows install puked? Can I fix this without a fresh install?

Hello and welcome to the forum

This has been a rather common error message with users trying to upgrade to windows 10.

The following error code x80240020 refers to "ERROR_SHARING_VIOLATION", which translates to the process cannot access the file because it is being used by another process. In order to fix this error message please follow the steps below:

Please open up a command prompt Window as a administrator, instructions for Windows 7 or Windows 8 and 8.1.
Inside the command prompt window enter in the following commands:
net stop wuauserv
ren %SystemRoot%\SoftwareDistribution\Download DL.bak
ren %SystemRoot%\SoftwareDistribution\DataStore DS.bak
net start wuauserv
wuaucault /updatenow

Wait a few minutes, once windows has advised all updates have installed you should hopefully have a message saying "Your upgrade to Windows 10 is ready"

If the above doesn't work follow the below steps:

Open up a new Notepad file (Press the Windows Key button on your keyboard and the R button -> Type in Notepad -> Press Ok)

Enter in the following text into the notepad file:

Code:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade]
"New Value #1"=dword:00000000
"AllowOSUpgrade"=dword:00000001

Click on File -> Save, name the file win10fix.reg and in the dropdown box for 'Save as type' select All Files (*.*). Save the file on your desktop.
Go to your desktop and double click on win10fix.reg, press Yes on any prompts.
Restart your PC and try and upgrade again.
