New member with an x64 prefetch issue (I think)...
Greetings, all,
Just joined the board because I have a strange problem with my new laptop with Windows 10 Home x64 (latest non-Anniversary version) that is driving me nuts.
Specifically, the problem is that the OS is not creating an NTOSBOOT.pf file in the prefetch folder. Instead, at each boot it creates or updates an individual .pf for EVERY file involved in the boot process, instead of consolidating the information in these individual files into the single NTOSBOOT.pf and suppressing the individual ones. As a result, the boot process is never optimized, and defragmenting the disk never gets the boot files placed in optimal locations for speed. The machine, not surprisingly, boots very slowly, but all other applications load very quickly. This has been going on for the 1 week I have owned the machine and through at least 20 reboots (both warm and cold).
I have looked at the registry key
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
where I see both EnablePrefetcher and EnableSuperfetch, and both are set to a DWORD value of 3, so that doesn't seem to be the problem.
Did MS, in its infinite wisdom, change the way prefetch handles booting up, or is something else going on? Any ideas would be greatly appreciated!
Regards,
Crashman
