Windows 7: Windows error: Unknown Publisher on windows files

Hi guys,

I have a Win7 Pro 64bit machine that is constantly coming up with a UAC box stating it doesn't know the publisher when I run windows programs, for example cleanmgr.exe.
I've attached a screen shot of the error message, sorry don't know how to embed the image.
I only get the UAC with windows files not other programs.
Any idea what's wrong?

On a side note, I discovered this when I found I was not able to do the windows updates on this machine, keeps giving me errors. Thinking they might be related.

Hello BSeanD,

Do you have administrator access on your machine?
Also, you can change your UAC settings by following option one from this tutorial. But it is highly recommended to keep UAC enabled, as it is a great security feature.


Good luck and keep us posted,

Hi Nommy,

Thanks for the reply.
Yes I do have administrator rights on the machine both domain and local. I wont be removing the UAC as it is a work machine.

I just don't understand how Windows doesn't recognise its own files.

As this is the same machine that cannot do updates and is in another state I just can fix it remotely, I need to be onsite. Since that's not going to happen I'm going to have to get someone in to look at it. Hopefully I can get some info to post when they look at it.

Hello BSeanD,

I do apologize for my late reply, your posts must have slipped under my radar.

Have you tried doing the SFC /SCANNOW command as described in option two of tis tutorial? If not, please do it three up to five times to make sure that it has fixed all possible errors.

If SFC doesn't fix the updating error, you might want to have a look at this tutorial on how to do a repair install of Windows.
Note: You will not lose any data or programs during a repair install, but it is still good to have backups of all important files.


Good luck and keep us posted,

Please forgive me for jumping in here but it looks like you are using "Remote Access" software here? That being so you will find that the UAC on the slave machine will always keep doing this. When I use Team Viewer the person at the other end needs to click the OK on the UAC window as it cannot be done remotely. That's what I find happens anyway! It's just another security aid in Win 7!

Hi mitchell65. Thank you for your reply. I too am using Team Viewer but I'm ok with actioning the UAC. My issue here is that windows does not recognise its own program, disk clean etc.

But does the operator of the machine get the same message regarding the program recognition if they access it direct?

Just an update. I haven't received this machine yet but will post my findings when I get my hands on it.

I've finally got my hands on the PC! I'll run a few tests and then get back to you with my results.
