Hi, the Windows Dianostic Tool has just stopped working which might be down to a recent series of Windows Updates on the 9th Dec

Definition Update for Microsoft Security Essentials - KB2310138 (Definition 1.189.1735.0)
Update for Windows 7 for x64-based Systems (KB3004394)

I've also ran a SFC Scannow which tells me that Windows Resource Protection found corrupt files but was unable to fix some of them, see attachment for details

Update KB3004394 was the issue for me. Uninstall that and restart then attempt to use the diagnostic tool.

Yes that was the culprit, thanks, i completed another SFC Scannow & no corrupted files were found this time round.

Will the next Windows Update automatically push out KB3004394 again? Microsoft should be told about that bug

Edit: Just checked & Windows wanted me to update to that again, so i hid it

Same problem, same solution. And the update is still being pushed out.

Some others (myself included) having problems with sfc /scannow "unable" result... dunno about Diag Tool

Hi,
I uninstaled KB3004394 today and it didn't came back!

Kb3004394

Should I remove KB3004394? It's not caused any issues for me at all but I'm reading that it's been pulled. Possibly it didn't cause any problems because UAC is switched off on my machine and has been replaced by an alternative.

I've checked and I have no issues with unsigned drivers or system files.

Thank you for your post. You saved my day and my sanity.

Hi, thats interesting about UAC & that could be the difference between it working for some & not for others, i have two different User Accounts on my Windows 7 system, one is a standard user for guests & the other is an Admin account that is password protected, ill also add that i did turn off UAC notifications because its nagging is a right pain whenever i download or install software, its one off the downsides to Win 7

You sir are awesome, that fix was searched hard and you had the only correct answer I knew it was an update but so many updates went in on fresh installs it would have taken forever 1x1. You nailed it congrats. Microsoft's solution? Repair install or format. I did reinstall 3 x thinking maybe faulty ram but after that I knew it was an update issue.

Thanks!

Hey new user here just wanted to say thanks to everyone that contributed-most frustrating 3 hours ever. I'm a rookie-took me forever to get everything straight but all good now. Muchas gracias

It may just be that I'm not extremely computer-savvy, and so don't really know what I'm doing, but when I search through the control panel update uninstall window, I can't kind the particular update that's causing this issue. The weird thing is that I can still see it in my update history as having been a successful installation. What should I do about this?

 

[Roseanne]

I have a program from i0bits called uninstaller, and it lets me see each item that was in the update clearly. its a free program, and I guarantee you ...the best uninstaller I have ever used. Give it a try.

This program from IOBit may (or may not) be the greatest thing since sliced bread, but personally I wouldn't touch anything from IOBit with a twenty five foot barge pole.

To me, it's a simple matter of trust. YMMV.

 

[Layback Bear]

I have seen to many problems on this forum caused by anything for IObit.

I don't even like typing the word Ixxxx.
Make my barge pole 50 ft.
