Windows stop BAD_POOL_HEADER error

Recover Windows to an earlier copy

If you're unable to boot into Windows because of this error, you'll need to boot into Windows Safe Mode and restore Windows to an earlier copy before being able to attempt any of the other suggestions mentioned below.

Install the latest service packs

Hardware drivers that are installed by third-party programs commonly cause this issue. Many of the errors will not be encountered if you have the latest Microsoft Windows Service Pack installed on the computer.

Get the latest hardware drivers

Install the latest drivers for any newly installed hardware device. If no new hardware has been installed make sure you have the latest drivers for the below devices.

  • Video card
  • Network card or router (if present)
  • Any removable or external disk drive

A listing of computer drivers and links to hardware manufacturers driver pages can be found on our driver's section.

Install the latest updates for software programs

Get the latest updates for software programs running on your computer. If you've recently installed a new program and have been getting this error, make sure no available updates are available for that program through the developers website. If no updates are available try uninstalling the program through the Add/Remove programs in Control Panel.

If no programs have been recently installed, temporarily disable programs from starting up with your computer.

Issue between drivers/software and Microsoft's Indexing Service

Disable the Indexing Service by following the steps below. Note: You must have administrator rights to follow the steps below.

  1. Click Start, Run, and type services.msc and press enter.
  2. Once in the services window scroll down to "Indexing Service" and double-click it.
  3. In the Index Services Properties window change the startup type to either "Disabled" or "Manual".

Issue with disk drive

As mentioned in the above causes to this error, if programs are having issues writing to the disk drive this error can be generated. Run ScanDisk on the computer to make sure no errors are present on the drive and if present that they're fixed if possible.

Bad hardware

Although this issue is almost always resolved by following the above steps, because this issue is generated with bad memory allocations or bad disk writes, it is also possible that the error could be related to bad hardware (e.g. bad memory or bad hard drive).

Before assuming that either of these is bad, we suggest erasing everything and re-installing Windows. This will help verify without doubt that this is not a software issue. If after re-installing Windows, and updating it with all the latest updates, you continue to get this error we suggest replacing the memory, hard drive, or both.
