Windows 8.1 recurring BSoD (BAD_POOL_HEADER)

Dump files - https://onedrive.live.com/redir?resid=5D2B2627890829C!462&authkey=!AGLwKEUk2zRCleM&ithint=file%2c.zip
I just upgraded my Windows 8 Pro to Windows 8.1 Pro and have been getting these BSoD's as soon as I reach the start screen.
Had to restart several times just to get into one working section, but lately since 3 days I can barely even boot in.
The BSoD shows right in the middle of the boot screen.
I have tried reinstalling Windows, it didn't work.
I am using mid 2011 21.5" iMac with Bootcamp.
Please help!!

The minidump files showed a BAD_POOL_HEADER (19) stop error caused by the MacHALDriver.sys:
BUCKET_ID: 0x19_20_MacHALDriver+1714
Bootcamp.exe is the process that crashes.
Try the following link for suggestions for this problem:

The dump files show its a problem with MacHALDriver.sys but I can't boot into Windows any longer, so can't disable the PnP driver.
Please help!

There may well be but it is years since I supported MS Windows.
Those two suggestions did not work, I would post your question on the Boot Camp forum.
Doing a web search it seems that this error is known but apart from the uPnP disabling which you cannot do I can find no other answer.
Try the other forum and hopefully someone there will be of help.

BSOD (BAD_POOL_HEADER) when scanning for Inventory

Hi All
I've set up a small testsite here.
It's a quite simple setup, with a few servers, a Zen10 CM server, and a few workstations.
It's all working quite nicely, but one of the machines does a BSOD (BAD_POOL_HEADER) when I ask it to do inventory. Taken from the event viewer it shows:
Error code 00000019, parameter1 00000020, parameter2 86ef6628, parameter3 86ef6740, parameter4 1a230001.
I have of course as a start, turned off inventory, but in the long run, that is of course not a solution, I would very much like to find out what's wrong.
The machine in question is an AMD Athlon X2 64 bit CPU, running 32 bit Windows XP sp3, with all the updates.
It has been used for testing all sorts of software, so it's for sure quite a mess registry / file wise.
Nevertheless it shouldn't BSOD the machine.
Just to make sure, I've exchanged the RAM, but it didn't change anything.
The Indexing service has also been turned of.
(That was the two typical messages I got from Google).

We've had the BAD_POOL_HEADER BSOD in combination with complex directory structures on NetWare servers (leading to paths longer than 255 letters) with Novell Client 4.9 SP2. SP5 fixed it.
Try analyzing the dump file. You should be able to see which process the blue screen triggers (in our case nwfs.sys).

I cannot install Adobe Reader 10.1.04 on my Windows Vista computer

I've been unable to install Adobe Reader on my Windows Vista (SP1) 32-bit Toshiba laptop, and would really appreciate some help.
Here's the error message I get:
Error 1402. Could not open key: UNKNOWN\.api\AcroExch.Plugin\ShellNew. Verify that you have sufficient access to that key, or contact your support personnel.
Here's a brief history of what I've already tried:
# 1 - Downloaded AdbeRdr1014_en_US.exe as a stand alone file multiple times from different servers and sites.
# 2 - Uninstalled Adobe Reader 9.0
# 3 - Ran AdbeArCleaner.exe multiple times to remove ANY perious verions of Acrobat and/or Reader.
# 4 - Opened each of my 4 browsers, latest verions of IE, Opera, Firefox, and Chrome, searched for Plugins and/or Add Ons and removed ANY Adobe related apps except Flash.
# 5 - Opened the Control Panel, Programs, searched for and removed ANY versions of Acro Quick Reader or Quick Writer.
# 6 - Ran Norton Utilities Clean Registry multiple times.
# 7 - When trying to install Reader 10.1.04 I had PREVIOUSLY received this error message:
Error 1402.Could not open key: HKEY_LOCAL_MACHINE\Software\Classes\AcroExch.Document\Shell\Open\Command. Verify that you have sufficient access to that key, or contact your support personnel.
However, after using Adobe Cleaning Tool, I no longer got this error.
# 8 - I also disabled my A-V Program during all installation attempts, Kaspersky PURE 2.0.
The reason that I wanted to update to Adobe Reader 10 was that Kaspersky did a vulnerability check which indicated:
"Adobe Reader/Acrobat Multiple Vulnerabilities"
See: http://www.securelist.com/en/advisories/47133/?function=advisories&VN=47133
Solution was to update to version 10.1.2 (or higher).
Now I can't open any .PDF files. I can't find the so-called Plugin which is causing the installation to stop. The installation of Reader 10.1.04 gets to around 96% complete, then fails and rolls back.
# 9 - Is there an easy fix, such as a tool that will autyomatically remove any relevant registry key, or apply the correct administrative attributes to the registry keys? If not, can you please talk me through this step by step. I've never been so stumped or frustrated performing a software upgrade, what I thought would be a simple task.
THANKS in advance for your help which is much appreciated.
Cheers,
Ecto

Hi Pat,
I feel like I'm falling deeper and deeper down the rabbit hole, operating in an area in which I am totally unfamiliar. I know a great deal about computers, but that still leaves me ignorant about many other things.
I had previously downloaded subinacl.msi in my research on Vista permissions and the inability to install Reader 10.1.04. In Vista, Windows Installer is a Service, not a program. I don't even understand what that means. I had previously tried changing the file extension of subinacl.msi to subinacl.exe but that didn't work. Then I looked for an EXE version of the file. No luck with that. Your pointing me to http://weblogs.asp.net/rternier/archive/2007/02/01/how-to-install-msi-files-on-vista.aspx was helpful up to a point. The post assumed I would know what to do with the bat file template:
"C:\Windows\System32\msiExec.exe -i C:\Users\rternier\Documents\Downloads\tfpt.msi"
I changed it to the following:
C:\Windows\System32\msiExec.exe -i C:\Users\aecolkercpa\Downloads\subinacl.msi
PLEASE NOTE: I store and run all downloaded installation files from the directory C:\Users\aecolkercpa\Downloads\
Usually, after installing a program from an installation file I will delete the installation file, unless there is a problem installing the application. In that case, I save the installation file until the problem is resolved.
Also, I am not sure if the first phrase in the BAT file I created is correct,
C:\Windows\System32\msiExec.exe -i
I called the file Install MSI.bat and ran as administrator.
I clicked on Accept the warranty terms, and the msi file began to be installed. Then I got a blue screen error BAD_POOL_HEADER with lots of text messages on it. I had to reboot. When I rebooted, Windows asked if I wanted to search for a solution online to the shut down, and gave me this report:
"Troubleshoot a problem with your antivirus software
A problem related to your antivirus software caused your computer to shut down unexpectedly to protect itself from data corruption or loss.
To try to solve this problem, follow these steps. One step might solve the problem, but if it doesn't, then go on to the next step.
Update your antivirus software
Missing antivirus software updates could be the cause of your computer's problem. To make sure your antivirus is up to date, follow these steps:
Click to open Microsoft Security Center.
Click Malware protection.
If your software needs to be updated, click Update now.
If Windows can detect your antivirus software, it will be listed under Virus protection.
If your antivirus software is not displayed in Windows Security Center, go to the downloads section of your antivirus software provider’s website. Find the update for your version of the software and your operating system, and then install it. For more information, check the Help for your antivirus software.
Most antivirus software updates are free, but some providers charge a small fee for the updates. If you're using an older version of the software, you might also have to pay to upgrade to a more recent version to continue to receive the updates.
Check for multiple antivirus programs running on your computer
Running two antivirus software programs on your computer at the same time is not recommended because the two programs can interfere with each other. Even if you don't think your computer could be running two antivirus programs, antivirus software can sometimes come bundled with your computer and it might be running without your knowledge. To check if two antivirus programs are running, follow these steps:
Click the Start button , right-click Computer, and then click Manage. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
In the left pane, double-click Services and Applications, and then click Services.
Look at the list of services under the Name column. If you find two antivirus programs, right-click each service associated with one of the programs, and then click Stop. Note that there may be multiple services running for one antivirus program.
Contact the antivirus manufacturer
If you've completed the previous steps, we recommend you contact the antivirus manufacturer directly for additional support."
Since I was unsure how to parse the BAT file, it probably contained errors, which may be the reason behind the blue screen crash. Should I have moved the bat file and the subinacl.msi file to the Windows/System32 directory before running it? To a different location than the download directory?
At this point I'm rather burned out. Perhaps 50+ hours of my time have gone into trying to install a simple program, Adobe Reader 10.1.04. I would love to succeed, but I think my lack of comprehension is making it even more difficult than it might otherwise be. Instead, I'm becoming more and more confused and frustrated by all these detours and additional issues.
Is it possible Pat to arrange for you to have remote login access to my machine using Go to My PC or some other application, so that you can hands on accomplish in perhaps 5 minutes, what might take me 5 more weeks (or months) to get done?
I feel we are close to solving this puzzle, but it keeps on slipping away.
Please let me know your thoughts, and thanks as always for your help.
Cheers,
Joel

possible ram issue, try to swap ram sticks first.
if it doesn't work, re-seat or seat one of the ram sticks ( remove another one ) and try.
i think it'll fix your bsod.

Windows Server 2012 reboots while removing the Hyper-V vSwitch.

I have a WIn2k12 server with Hyper-V running. While removing the vSwitch configured in Hyper-V, the server got rebooted. In the event logs below mentioned error was notices.
he computer has rebooted from a bugcheck. The bugcheck was: 0x00000019 (0x0000000000000024, 0x00000000000000f2, 0x0000000000000001, 0xfffffa800b9ba6c0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 072314-20248-01.
The Windows has generated a MEMORY.dump which is ~570MB in size. Is it possible to analyze the MEMORY.dump and find the cause for a server reboot.
Can you please someone help me to narrow down the root cause of this issue and how to avoid this issue in the future.

Hi,
Thanks for your reply. I analyses the the MEMORY.DMP using the WinDbg. Provided the debug output below. Will this help you to narrow down the root cause and let me know if any similar issue faced by someone else.

Windows 8 crashes in boot camp.... bad pool header

I continuously am forced to reboot window's 8 in bootcamp due to a blue screen. The majority of time the error states "Bad_pool_header" but there are times when it is another message.

I would point out as I did above:
I also installed the Boot Camp special hardware.
you are running Windows.
Boot Camp (Assistant) partitions the drive, and in Lion downloads Windows Support software.
Lion 10.7.4 w/ Boot Camp 4.01 is the better choce.
With Windows you will always be on your own and need to update drivers.
Apple isn't going to until after 8 is either released or is finalized, and maybe only for Mountain Lion (guess based on past)

Can't Install Windows on H55M-E33

I just bought this new sets of PC :
Processor : Intel Core i3 550 3.2Ghz Box
Motherboard : MSI H55M-E33
Memory : Team Elite Dual Kit 2*1 GB TED32048M1333HC9DC (I assume PC10600) Timing : 9-9-9-24
VGA : GeForce GTS450 1Ghz
Harddisk : Hitachi SATA 1TB
Maxtor IDE 160GB (this one is old stuff)
The Main problem here is when i tried installing windows, I kept being told by setup that a random file is somewhat corrupted and sometimes end up with BSOD like BAD_POOL_HEADER or ERROR_IN_NONPAGED bla bla. Sometimes it don't. Anybody knows what happen here ?
NB : Actually this don't happen just with XP, Also with Vista and Windows 7, So I ended up with a piece of electronic junk

How much RAM do you intend to use? 2GB or 4GB.
This is what I use and is very good top quality RAM and is what I always recommend for H55/H55M/H57M in particular and just about all the rest in general. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148262
"(i prefer 1333 so i can still pair it with my old memory)"
By that do you mean mixing your current RAM with other new RAM?
You should not mix RAM brands, sizes, speeds or whatever. Sometimes you get lucky and it works OK but more often it's just one problem after another when you do mix like that.

Windows 8.1 - \windows\system32\winload.efi missing or corrupt Code: 0cx000000f

I have had my Lenovo IdeaPad U330 Touch 4th Gen i5 for 5 months now, and last week, lots of blue screen errors started appearing. Here is a list of the BSOD Errors I had DURING ONE DAY:
BAD_POOL_HEADER
PAGE_FAULT_IN_NON_PAGED_AREA
MEMORY_MANAGEMENT
KERNEL_SECURITY_CHECK_FAILURE
PFN_FILE_CORRUPT
BAD_POOL CALLER
ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY
Anyway, It worked fine this morning, but after I came back from lunch, It told me that my computer needed to be repaired, because the file \windows\system32\winload.efi was either missing or contained errors. I have 3 options on this screen which are:
"Press Enter to try again" - which does nothing
"Press F8 for Startup Settings" - which does nothing
"Press Esc for UEFI Firmware Settings" - which works and takes me to the "InsydeH2O Setup Utility"
What do I do to get my laptop working again??

Hi,
How about your problem now? According to your description, the only way except reinstall OS to fix your problem was create a system repair disc, USB drive is OK. Then connect to your computer to fix this problem.

Satellite P70-A-112 - Windows 8 - Bug with Application Manager & Display

Hello,
I bought this Toshiba laptop in August with windows 8 (64 bit) inbuilt.
It all began yesterday, when Windows crashed due to a "BAD_POOL_HEADER" error. Ever since, I cannot access the "start menu" of Windows 8, neither can I run any applications linked to this tablet-like menu. For instance, I can't even open a picture anymore ou neither can I open a PDF file with Acrobat Reader.
My problem is thus twhreefold:
Firstly, it seems that the Application Manager does not seem to run when I start the computer. And this application manager seems to be necessary to run the start menue.
Secondly, I cant access the parameters of my computer when putting my cursor on the top-right corner, making it impossible to close my computer the normal way.
Thirdly, when I manage to restart my computer, I arrive most of the times to a black background, and just a non-working picture picture of the quick access bar at the bottom of the screen. Nothing works.
Oddly enough, the only way I've found to "solve" this problem is by pluging-in a second screen. However, it is merely a temporary solution: whenever I de-plug the second screen, the nightmare begins again.
Could you please help me identify the exact problem and help me solve it?
Thanks a lot.

> According to other forums on the net, it might be a hard-drive problem.
Yes, probably its memory module problem. I think the memory modules should be tested.
> What to do?
Your notebook is new. Right?
This means that warranty is valid and hardware problems should be fixed under warranty conditions.
In my opinion you should as your authorized service provider for assistance.

Problem with Threads and "plase wait..."-Window

Hi everyone,
I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
decrypt-file code:
public class DecryptFile {
private String cryptedFileNameAndPath;
private ByteArrayInputStream resultStream = null;
// need for progress
private int lengthOfTask;
private int current = -1;
private String statMessage;
public DecryptFile(String encZipFileNameAndPath) {
    cryptedFileNameAndPath = encZipFileNameAndPath;
    //Compute length of task...
    // 0 for indeterminate
    lengthOfTask = 0;
public ByteArrayInputStream getDecryptedInputStream() {
    return this.resultStream;
   * Called from ProgressBarDemo to start the task.
public void go() {
    current = -1;
    final SwingWorker worker = new SwingWorker() {
      public Object construct() {
        return new ActualTask();
    worker.start();
   * Called from ProgressBarDemo to find out how much work needs
   * to be done.
public int getLengthOfTask() {
    return lengthOfTask;
   * Called from ProgressBarDemo to find out how much has been done.
public int getCurrent() {
    return current;
public void stop() {
    current = lengthOfTask;
   * Called from ProgressBarDemo to find out if the task has completed.
public boolean done() {
    if (current >= lengthOfTask)
      return true;
    else
      return false;
public String getMessage() {
    return statMessage;
   * The actual long running task. This runs in a SwingWorker thread.
class ActualTask {
    ActualTask () {
      current = -1;
      statMessage = "";
      resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
      current = 0;
      statMessage = "";
}The code that calls decryption and displays waitWindow
      final WaitSplash wS = new WaitSplash("Please wait...");
      final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
      cryptedTemplate.go();
      while (! cryptedTemplate.done()) {
        try {
          wait();
        } catch (Exception e) { }
      this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
      wS.close();Thanks, thanks, thanks in advance!

Maybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...

I install window 8 and Unfortunatly all drive format. And all drive mix, now i have only 1 DRIVE C. I want Bit locker Drive's data Back

Last sunday i install a window 8 and this window format my all drive & make it 1 drive (DRIVE C). Before all of this i have 5 drive in different size with 1 Bitlocker protect drive.
So i try data recovery software to recover my data. i got back all my data without that ( bitlocker ) protected drive.
so please guys help me how can i get back data from bitlocker protected drives.
please please help me.

Hi,
I sorry for your experience, but there is no way to recovery the data encryped by BitLocker untill now.
BitLocker is designed to make the encrypted drive unrecoverable without the required authentication. When in recovery mode, the user needs the recovery password or recovery key to unlock the encrypted drive. Therefore, we highly recommend
that you store the recovery information in AD DS or in another safe location.
Please refer to the link below for the statement:

HP LaserJet Enterprise 500 Color MFP M575 - Can't scan from Windows

We recently purchased and installed an HP LaserJet Enterprise 500 Color MFP M575 to be used as a networked all-in-one solution for a number of offices. I have been able to get it set up on our network and have installed the appropriate drivers on the requested Windows 7 x64 machines, and network printing works perfectly. However, it seems that despite the fancy scanning features available from the all-in-one itself (scan to email, scan to a network folder, etc.), I can't find any way to do an old-fashioned scan from Windows.
I have installed the full software solution available on the driver download page for the device, and while Windows lists the device as a "Multi Function Printer; Scanner" it does not recognize it as an actual scanner. The built-in Windows Fax and Scan simply reports that no scanners are installed. The software installation did not include the HP Solution Center (which I am used to seeing from my experience with various other HP all-in-one devices) or any equivalent for direct scanning. The driver download page for the device does not include any separate scanning drivers, so I can't be certain if they were included with the full installation or exist at all.Some of our staff also use Adobe Acrobat to scan, and even that fails to recognize the MFP as a scanner.
We'll eventually be setting up the device to scan directly to a network folder, but we need a fallback while IT takes their time getting it set up; I can't imagine that the simplest option is not available at all. I must be missing something here, any assistance would be greatly appreciated.
Edit: To add, I also ran the HP Print and Scan Doctor. Interestingly, it reports the device as a printer and only offers to "Fix Printing" without any sort of resolution for my scanning problem.

There is no change to this problem after 6 months since the last post. Put simply, and as stated in the previous posts, there is no way to scan a document and receive the image on your PC. If you are working with graphics for any length of time or want to create an image for inclusion as an image in a document or web page using this piece of equipment will not allow you to do so.
Great shame as every other function works well - it cannot be beyond the wit of HP to include a Windows application that enables you to scan an image, receive it in the software you are using at the time (e.g. Outlook, Word, Photoshop...) and use it in your work.
HP Printers several years older than this £1000+ Enterprise printer were able to do this simple job and have done so for a great many years. Just being able to use Microsoft's Fax and Scan would be start.
