The default value for this key has been changed to 1 for Windows Server 2008 and Vista.
The setting may affect the behavior of file usage reports and backup software if they rely on the last access timestamp. I have been using this setting on Windows file servers and its operational equivalent on Linux file servers for a long time without incident. The last access timestamp is not useful in my environment. I have not done any benchmarking or testing using this setting on desktop operating systems. I would be interested to hear if this setting yielded any noticeable performance increase and on what type of workload. Hope this helps... From: Michael B.

While I'm not going to tell you that it WON'T affect your applications, I will tell you that I've never had a problem with using it. Regards, Michael B.

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??
