It's Windows...or better NTFS.

By default NTFS will automatically update timestamps whenever a directory is traversed. This isn't a necessary feature, and it slows down large volumes.

Disable it by pointing regedit to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem and set 'NtfsDisableLastAccessUpdate' to 1.

If the key doesn't exist yet, add it (DWORD value). And you have to reboot after changing the key.
