Blue screen using Regedit

[Chucktronic]

Whenever I do a search within my registry, the search engine
always crashes into a Windows blue screen fatal error:

"A fatal exception 0E has occured at 0028:C023A652 in VXD Perf(05) +
000001B6"

I was able to trooubleshoot the Keys that cause the error and they are:

HKEY_DYN_DATA\PerfStats\StartStat
HKEY_DYN_DATA\PerfStats\StatData
HKEY_DYN_DATA\PerfStats\StopStat

If I delete the \PerfStats root Key, the problem disappears
but the keys are regenerated at boot up.

What could the problem be ?
Could it be a virtual driver that fails to install properly at startup ?

Have a read - see if this helps:

"Once every month or so, a client calls me with a typical Win9x problem:
Windows has somehow trashed its own Registry.

The damage is never quite the same twice. Typically, there's been an
unexpected crash, followed by new and undesirable behaviors. Windows
loses track of devices, loses user preferences, starts crashing
sporadically, won't run certain processes, or what-have-you.

The cause, apparently, is that Windows has crashed while in process of
re-writing Registry data to the hard drive (which it seems to do very
frequently). The next startup, it repairs the damage after a fashion,
re-assessing hardware and such, but most often data is lost that can't
be recovered.

I manage to fix it manually about half the time, with device re-installs
and such. The rest of the time, I usually have to reinstall Windows.

The latest patient had lost its ability to run a video display -- any
video display -- at any but the most basic setting: 16 colors, 640X480.
Any setting involving higher resolution or more colors would cause a
complete crash, or a totally out-of-sync display. Alternate video cards
and driver re-installs did nothing. The system was squirrely in other
ways too, running slowly, hanging on shutdown and prone to crashing for
no apparent reason.

After several efforts to deal with the symptoms, I concluded that as
there was no backup, and since the Registry was virtually unrepairable,
what the machine needed was to have Windows re-installed.

BUT. The client, because of the many applications and the large amount
of personal data on the system, didn't want that; except as an absolute
last resort.

I thought it over. When Windows trashes its Registry, it typically
LOSES data. I have never yet seen it retain corrupted data; I think it
usually either ignores or discards whatever may have been garbled.

So, what I needed was -- if possible -- to somehow restore what was
lost, while retaining what I had left of the Registry. I needed a
functional new Registry onto which I could overlay the surviving
Registry data.

I formed a likely plan, and I did this:

1. Exported the entire Registry to a .reg file on the desktop.

2. Rebooted to a command prompt-only session. Typed in these commands:

C:\>attrib -s -h -r system.1st

(This makes visible/movable the backup copy of the _original_
SYSTEM.DAT as first installed by Windows.)

C:\>attrib -s -h -r c:\windows\*.dat

(This makes the current Registry files visible/movable.)

C:\>copy c:\windows\system.dat c:\windows\system.da1

C:\>copy c:\windows\user.dat c:\windows\user.da1

(These commands create backups of the hammered Registry just in
case.)

C:\>copy /y system.1st c:\windows\system.dat

(This reverts the Registry to a new-Windows-setup state.)

3. Rebooted to Windows. It started up as if for the first time ever,
demanding a product ID and so forth. It went all through the hardware
recognition process, which I helped along at a couple of points. It
required a couple of reboots to complete.

4. Once Windows was up and running properly, I immediately
double-clicked on the .reg file I had earlier created. Regedit reported
success importing its data.

5. Rebooted to a command prompt-only session. Typed in these commands:

C:\>attrib -s -h -r c:\windows\*.dat

(This makes the hidden Registry files visible/movable.)

C:\>copy c:\windows\system.dat c:\windows\system.da2

C:\>copy c:\windows\user.dat c:\windows\user.da2

(These commands create backups of the new "hybridized" Registry --
just in case.)

6. Rebooted to Windows. Tested all applications, various file
associations, the video performance (of course), etc.

Result: 100% success. Every app worked, video problems totally solved,
no weird behaviors, Windows was starting and running much faster, and
shutting down properly.

I'm sure I'm not the first to think of this approach, but it's new to
me, and I did think it up on my own. I think I can add a feather to my
PC-Service-Dude propeller-beanie.

OK, note this also: I just realized, steps 4 and 5 are reversed in my
original account. I didn't back up the "hybridized" registry, I backed
up the one I'd just built in the new-setup process. Then I incorporated
the .reg file and rebooted without making a backup."

I know the procedure and I always keep a backup of my registry.
I tried to restore my backup more than one time and didn't solve my problem.

Thnx anyway ...
