For me the story is mostly the same as the first poster.. Except that the broken fileassociations were taken care off in an automatic scan.. A few hours later more and more programs started to malfunction.. So I rebooted.. After the reboot, Windows started, but no other program were able to start.. each time I tried to start a program it would tell me that there was no program associated with the extension .exe so that I need to install a program that could deal with that extension.
So now I have a completely non-functional Windows 7 Ultimate edition 64-bit.. I have a diskimage a few weeks old, but I am still hoping to find a solution to restore the current.. I can't even get SAS to start to let it undo it's damage.
I hope that somebody can give me advise to make the programs start again.. I do have a WinPE to access the computer with programs.
When booting "normally" I have a network. And for some reason windows explorer is the only program willing to start by itself, but no copying or pasting. I can use explorer to start programs that start by clicking on for example png, jpg, etc files.. So file-associations other than .exe seem intact, but even these programs fail if they try to startup other programs.
Please has anybody any idea?
