  If you use Norton, AVG, Avira, Microsoft Security Essentials, McAfee, etc. the default action is for Windows Defender must be disabled, that these AntiVirus programs have their own Antispyware Applications.

  There is nothing to worry.

  Using both programs at the same time can cause system conflicts, etc.

  If you are using one of the above AntiVirus programs, this Information from David O - Support Engineer shows you how to manually enable Windows Defender (disregard information from uninstalling; not possible in Vista):

  http://answers.Microsoft.com/en-us/Windows/Forum/windows_vista-security/how-do-i-manually-start-Windows-Defender-in-Vista/dab845b2-9ba5-47F3-9518-c4c6781e7d5b

  Right click and select Properties , ensure that Startup Type is automatic.

  Once modified, click apply and OK.

  Quit and restart your computer. Check the back take the same path to confirm that Windows Defender has started"

• Cannot activate Windows 8 error "the Software Licensing service determind that specified only usable product key for the upgrade not to own pieces."

  Original title: invalid product key :(

  Today, I tried to load my computer and was faced with the blue screen error short story that my hard drive some how became corrupt and had no partition. Fortunately, I had a friend who told me step by step how to solve this problem using my hard drive in my brothers pc. When it came to reinstalling windows I booted the computer directly from my windows disc 8 and when I tried to activate the key once I was ready to I received an error Code: 0xC004F061Description: The Software Licensing service determind that specified only usable product key for the upgrade not for own pieces. Means that I can not use the key I bought and must buy a new one? It seems really unfair because I've already spent money on the upgrade.

  You upgraded to Windows 8, but did not have an earlier version of Windows Installer (error 0xC004F061)

  If you see error 0xC004F061 when you try to activate Windows 8, this means that you are using a product key for an upgrade of Windows 8 version and a previous version of Windows wasn't on your PC when Windows 8 was installed. To install a Windows 8 upgrade version, you must already have Windows 7, Windows Vista, or Windows XP installed on your PC.

  If you have formatted the drive until the upgrade of Windows 8 version has been installed, you will not be able to use your upgrade product key to activate Windows 8. To activate Windows 8, you will need to install your previous version of Windows, and then reinstall Windows 8. Help with the activation process, contact technical support.

  You are running Microsoft Security Essentials, AVG, Norton or McAfee?
  If you run one of those, she didn't have Defender. It's
  good, not bad. Not only is there potential conflict, but there is no
  reason to have both; essentially, they have something very similar
  for the Defender integrated and running both at once will hurt your
  performance and create the risk of problems that are contrary to each
  others.

• Cannot activate Windows 8 error key is already used by another pc.

  OT: Product key Windows 8.

  Hi, so I bought windows 8 pro a year ago and installed on my laptop but I recently bought a new desktop computer and gave my laptop to my sister. She didn't so I put windows 7 on the laptop for her and went to put windows 8 on my windows desktop 8. It installed fine but when I go to activate windows it says that the key is already used by another pc. Why he says this when the computer that I had windows 8 is no longer a windows 8?

  You use telephone activation. The database of activation of Microsoft still has your old laptop, saved using the key of Windows 8.
