Every time you access a file on your windows computer, a Last Accessed file attribute is updated. You will likely not need this, so you can remove some overhead by following this guide. This guide is for Windows XP. Last access is disabled by default in Windows Vista.
Please Note: This guide involves working with the Windows Registry. If this is your first time editing the registry, please read this guide to get you started.
