No, i think it would work if you use sign tool from MS SDK. Problem for me the file (that you can found in the hole SDK) is to large for my internet. So i can't use it. If someone would give me that tool i would be verry happy .
is this sdk tool something i can just download and put on a hosting site for you or is it more complicated? im very interested in the taskmanager from w8, it the one thing i absolutely fell in love with on the preview.
Download: Microsoft Windows SDK 7.1 - Microsoft Download Center - Download Details
in this SDK there must be a little tool called signtool.exe. But this tool needs the whole SDK is think. The only think that i think i need to do is make a licence for that tool and sign it for myself. But i'm not sure if it wil work. Grr i hate belgium with his stoppid download limit! Can you believe i pay 25 € per month for 30Mbps and i get 1,5 Mbps or 340 kb/sec :s .
