As Dan said it is disabled by default in Vista and 2008 Server .

XP box is an old Dell p3 866 with 450g of storage. IE, my home server.

But this guy insists its made his home server, and PC much faster and wants to do it to his work one. I am wary, working on the asumption if it made such a huge difference wouldnt MS have made it a default setting.

If there are a lot of accesses, a waiting list is constructed in RAM and this can really sap performance to speed up your NTFS partitions do the following 1. go to HKLM\SYSTEM\CurrentControlSet\Control\FileSystem 2. find or create a DWORD "NtfsDisableLastAccessUpdate" and set its value to 1. He claims his PC is now noticeably faster. My question is it safe to do this, and if it makes such a difference is it worth doing on all PC's and possible servers??
