Hi, I've written a batch which replaces cca. 80 system files (installs shellpack, more precisely), but even if SFC is off, these files wont't overwrite (e.g. explorer.exe, cause its obviously in use). If I want to overwrite all of these files, will adding an item (which will run that batch) into RunOnce key in registry solve my problem?Any other suggestions will be appreciated. ...and sorry for my poor english
