Hyper-V isn't uninstalling.  It has had some errors.  Are there any known programs that cause such error?  I need to get rid of the Hyper-V role.  When trying to uninstall, I get this error:

 

Hyper-V: Removal failed

<Error>: Attempt to un-install Hyper-V failed with error code 0x80004005. Error HRESULT E_FAIL has been returned from a call to a COM component.

Have you tried stopping all the Hyper-V services before removing the role?

go to the powershell(select with run as admin)

 

 

Import-Module servermanager

remove-windowsFeature Hyper-V

 

 

 

What do you mean by "trying to uninstall"?  The proper way is to remove the role in server manger.  What events are logged?  Can you post them?  80004005 doesn't help a lot; it's a generic EFAIL.

You can't on core unless you're using sever manager remotely.

Dear John,

 

please see below mentioned things

Tasks that you cannot perform remotely by using Server Manager

Primarily to minimize security risks to your servers, the following tasks cannot be completed in a remote Server Manager session.

• Add or remove roles, role services, and features
  
  
• Configure Remote Desktop settings
  
  
• Configure System Properties
  
  
• Check for new roles
  
  
• Change Windows automatic updating settings
  
  
• Change network settings
  
  
• Change the computer name or domain membership
  
  
• Change Internet Explorer Advanced Security Configuration settings
  
  
• Run the Security Configuration Wizard, if the source computer is a server that is running Windows Server 2008 R2

you cannot add server roles on remote computer

Hi All

i'm having the same problem when try to remove the hyper-v role; i actually need to reinstall it. We had a raid failure with some hd corruption and restored from a sys state backup. it appears the role is installed in the server manager gui, but the service or any of the features of the role are not there. when i try to uninstall through the server manager i get: <error>: attempt to un-install hyper-v failed with error 0x80004005. error hresult e_fail has been returned from a call to a com component.

when i try to uninstall via the powershell i get:

all help is appreciated!!

thanks in advance

john

any one??

I assume that you are running this hyper-v on a core installation of windows server 2008, and assume that you have no other roles installed on this server, so if all these assumptions are try, then why not just format and reload the OS?

I mean it's much quicker to do that than having to fight a failing removal process.

just a thought.

have you tried this:

Dism /Online /Disable-Feature:Microsoft-Hyper-V-All or Dism /Online /Disable-Feature:Microsoft-Hyper-V
