Windows Performance Analyzer error

Question

Hi..

I'm new to the Windows Performance Toolkit and would appreciate some help with regards to an error I have been receiving.

It occurs after running the following command:
xbootmgr.exe -trace boot -prepSystem

The system reboots and the trace process continues as it should.  Then the system restarts again and after the trace countdown finishes after logging back on, i'm faced with the following error:
Failed to save prefetcher data (C:\Windows\prefetch\layout.ini) in cab archive (stage 1, error 0)
Failed to defragment disk after 5 attempts.
PrepareSystem failed.
Couldn't find kernel logger in active logger list.
Couldn't find user-mode logger in active logger list.

I have recently trialled UltimateDefrag 2008 and when launching the program, it offered to disable boot optimizing as it could interfere with the defrag process.  I allowed it to change the setting and assumed that any changes would be reversed when I uninstall the program.  I have since uninstalled UD2008 and have had to reset the registry value manually.  However, i'm not sure if there's any other changes UD2008 may have made that could be linked to the error above.

I'm running Vista Ultimate x32 SP1 plus all updates
Intel E6600 conroe overclocked to 3.2GHz (stable)
2GB Corsair DDR2 XMS2-6400C4 RAM
ATI Radeon HD 3850 Pro Xtreme 512MB GDDR3 GPU
Corsair HX620W Modular PSU
ASUS P5K-E WiFi

Any help would be greatly appreciated.  If you need any further information, i'll be happy to provide it.

Thanks in advance :)

Hi Nick,

Which version of WPT are you using?

Thanks,
Michael

Answer 2

Hi Nick,

Which version of WPT are you using?

Thanks,
Michael

Hi Michael,

thanks for the reply and apologies for the delay in getting back to you.

I'm using WPT v4.1.6512

Answer 3

Hi Nick,

Can you please try to repro using WPT 4.5 that is part of the Windows 7 RC SDK? You can find the ISO here: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=6db1f17f-5f1e-4e54-a331-c32285cdde0c and the web-installer here: http://www.microsoft.com/downloads/details.aspx?familyid=F75F2CA8-C1E4-4801-9281-2F5F28F12DBD&displaylang=en.

Let me know if you are still hitting the same issue.

Thanks,
Michael

Answer 4

Hi Michael..

I finally got round to downloading the ISO and extracting the new version of WPT.  I get a similar error now when I run:
xbootmgr.exe -trace boot -prepSystem

Failed to defragment disk after 5 attempts
PrepareSystem failed
Couldn't find kernel logger in active logger list
Couldn't kind user-mode logger in active logger list

If you have any suggestions, I would be very grateful

Cheers..

Nick :)

Hello All !

I got the same problem, with WPT 4.1, I got this error message when I do "xbootmgr.exe -trace boot -prepSystem":

Failed to save prefetcher data (C:\Windows\prefetch\layout.ini) in cab archive (stage 1, error 0)
Failed to defragment disk after 5 attempts.
PrepareSystem failed.
Couldn't find kernel logger in active logger list.
Couldn't find user-mode logger in active logger list.

but when I use WPT 4.5 my computer reboot six times (against two with WPT 4.1) and xbootmgr freezes when it try to defrag, then after a reboot
it can save prefetcher data but still can't defrag, error:

Failed to defragment disk after 5 attempts
PrepareSystem failed
Couldn't find kernel logger in active logger list
Couldn't kind user-mode logger in active logger list

Hey Guys :)

Here some news...

The ReadyBoost service (EMDMgmt) was disabled, so I put it on Automatic Startup,
and, in Reliability and Performance Monitor -> Data Collector Sets -> Startup Event Trace Sessions -> the ReadyBoot item was disabled, so I activated it...
and re-run xbootmgr...

I've win more than a minute in boot process (1 min. 50 sec. before and 0 min. 40 sec. after changes to boot)

but xbootmgr is still freezing when it try to defrag !

log xbootmgr:

Answer 7

I have got it working on my pc now....more luck than judgement though.

@Tuxtox: Let us know what values you have under the following registry keys please:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Prefetcher

All I did was change one value and created another and it works ok for me now.

Answer 8

Hello Nick,

I am happy that it works for you,
my registry values are the following ones:

for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

Enable = N
LcnEndLocation = 0
LcnStartLocation = 0
OptimizeComplete = No
OptimizeError = Missing Registry Entries

and for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Prefetcher

BootFilesOptimized = 1
LastDiskLayoutTime = 8b b3 8c 31 48 fa c9 01
LastDiskLayoutTimeString = 2009/07/01-14:33:53

Thanks

Hi Tuxtox,

For the first key, my 'enable' value was already showing as Y but the 'optimize complete' value was N so I changed that to Y

Under the second key, the BootFilesOptimized key was missing so I added it with the 1 value then after rebooting, xbootmgr was able to complete without an error.

I'm not sure if this will help in your case as the 'Missing registry entries' value may point to a problem elsewhere so before you try changing anything, take a backup or the keys and create a system restore point.

Hope it helps :)

Answer 10

Hi Nick,

Thanks so much for your help :)

Now it's working perfectly, I've only change theses values in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

Enable = Y
OptimizeComplete = Yes

and the value OptimizeError is now empty.

Thanks again,

Bye !

You're welcome....glad you got it working :)
