| 1196265 | 2011-04-21 22:34:00 | This morning when I turned on my computer I got the following error message: An unauthorized change was made to Windows. You will no longer receive notifications, including those about your licence or activation. Use the link below to find out how to fix your system. Error: 0xC004D401 Description: The security processor reported a system file mismatch error. Learn more online [which takes you to a Genuine Windows website.] I have genuine products and the only thing I did yesterday was an Apple software update. I searched online and found it could be due to a couple of things, but the explanations of what to do were quite complicated (and in some cases the person with the problem had done certain diagnostic tests that I don't know how to do). Any easy explanations on how to fix it? If it needs fixing? I realise it's likely to be something I've updated recently, but the error message keeps popping up and it's quite annoying. |

| 1196266 | 2011-04-21 22:40:00 | Have a read of this (support.microsoft.com) There maybe a program on the hdd (that you've installed), that isnt compatible with whatever version of windows you're using |

| 1196267 | 2011-04-21 22:47:00 | Not quite the same unfortunately - that refers to unauthorised changes being made to the Windows licence - this just says to Windows. I haven't installed anything new, just updated any Apple software (iTunes, etc) and joined YouSendIt. Never had this message come up before and by the sound of it, once it does, you keep getting the pop-up! I'm using Windows Vista Home Premium. |

| 1196269 | 2011-04-21 23:20:00 | Have a look at This web site (www.techrepublic.com) - it will tell you have to do a Diagnostic Report, once done look for the file mismatch error in the Diagnostic Results - that will tell you what is causing the problem. It could be one or two of MANY possible causes, and without the info, its only guessing as to whats cause the error. Edited: waiting for the report is a LONG 60 seconds :D |

| 1196270 | 2011-04-21 23:32:00 | Ta - and I just got back to the computer and found another error message (it popped up the first time too, but forgot about it): The backup application could not start due to an internal error. (0xC004F027) Please check your system configuration and try again. I'll have a look at that website and see if I can figure out what to do. I have Avast, not McAfee, if that's what you're asking. |

| 1196271 | 2011-04-21 23:45:00 | Right, got a big long report but am not sure how to interpret it. I'll put the edited results below. Under error it has: A service is reported as having an unexpected error code... resolution is to restart the service. Informational: D: has less than 15% free disk space (this is my recovery drive)... perform a disk clean up. Symptom: The Security Center reports that User Access Control is disabled... enable user access control. I assumed I would find that in the Control Panel, but when I click on that in the start menu, it starts to appear then disappears. I've tried it several times with the same result - I can't open the Control Panel. When I clicked to get more information under the User Access Control part, it just opened a website for Windows Vista Help - not sure where to go from there. |

| 1196272 | 2011-04-22 00:00:00 | The control panel not opening is a start. Meaning there is at least something wrong and you're not going nuts :D yet :p You can try opening the User account control -- click start, type in UAC, select user account control, and hopefully it will open. if that doesn't work, have a read of This article Post #8 (www.vistax64.com) Try this - open a command prompt - click start, type in cmd right click it in the results, type in sfc /scannow - press enter -- go and do the lawns , clean the house or something it may take a while to run. This will check for damaged system files, it may fix them, may not. There is a possibility as well that an infection of some kind it in there, as they can cause the control panel to malfunction. BTW- I'm assuming your OS is Vista ? -- all the commands I posted are from W7, but should work in Vista as well. |

| 1196273 | 2011-04-22 00:04:00 | I just did a restart (after doing a disk clean up on all my drives - something happened only for the C drive, not the others) - and didn't get the error message when it all came back up - and I could open the Control Panel again! Yes, I'm using Vista. I'll do what you suggested and see if that helps too, ta. |

| 1196274 | 2011-04-22 00:22:00 | It has finished and says: Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS\log. For example C:\Windows\Logs\CBS\CBS\log I must confess I have no idea what that end bit means or where to find them! |
