installing diskperf on vista business.

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi all,

Few months back, I tried to install driver (wdk sample ) diskperf on a
vista business laptop with one hard drive by right-click on
diskperf.inf Windows Explorer and select "Install" from the menu that
is displayed in vista. But i always get message inf that selected does
not support this method of installation. So I remove the name
decorations (like NT etc ) and I was able to install and use it
successfully.

TOday I again tried to install it on a desktop which has two hard
drive, but no luck. I do not get any error message.

So i removed the secondary hard drive and tried with just the boot
drive but again no luck.

SO I tried manually install the DDK sample driver diskperf by
performing the following steps:

[These are exactly the same entries as on my laptop with working
diskperf]

1), Copy diskperf.sys to c:\windows\system32\drivers\

2), Modify the registry as follows:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-
E325-11CE-BFC1-08002BE10318}]
; This entry is for DiskDrive

"UpperFilters"="diskperf PartMgr" ; PartMgr is another upperfilter

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\diskperf]

"ErrorControl"=dword:00000001
"Start"=dword:00000000
"Type"=dword:00000001
"Group"="PnP Filter" ;
"ImagePath" = REG_EXPAND_SZ:system32\DRIVERS\diskperf.sys

and other entries copied ditto


but I get an error at the boot time (even before the windows progress
bar comes), saying that critical driver file \SYSTEM32\DRIVERS
\diskperf.sys is either missing or corrupt.

Then I changed the "ImagePath" = REG_EXPAND_SZ:%system%
\system32\DRIVERS\diskperf.sys and I got the error message again at
the startup (even before the windows progress bar comes) saying that
critical driver file \WINDOWS\SYSTEM32\DRIVERS\diskperf.sys is either
missing or corrupt.

Note the difference in error message. To me it appears it looks like
it is not able to find the diskperf.sys.

Please help. Thanks.
