up until june, an old batch file in my 64-bit vista startup worked fine, but all of a sudden, vista started asking for permission to run the batch file because it does not have a "proper digital certificate." is there any way to stop that? i wrote the batch file and all it does is write the time and date of booting up intomy log file. i've been using it since my winNT days.uac is not turned on.

Hi DyNama, I consider the issue can be caused by missing certificate. I suggest you first perform a System Restore and see if we can restore the certificate and let the batch file working properly.
