The “bad pool header” error is caused when your computer cannot read a certain setting / file that it needs to from its “data pool”. The data pool is simply a storage facility for all the data and settings that Windows is currently using on your PC. It’s like a “handbook” for your system, which Windows can use to quickly find information for various elements of your system. Many people have reporting seeing the “BAD_POOL_HEADER (0x00000019)” error on their PC’s, and this article is going to give you a solution which should solve it.

This error is caused by two possible reasons – the first is that you have a problem with the file system of your PC (preventing Windows from reading the files it needs), or you have an issue with some settings / data on your system.

The first thing to do to resolve this problem is to update your PC. Microsoft have released various updates for the Windows system that have cured most instances of this error. To ensure you have them, you should click on Start > Control Panel > Windows Update and then select all the updates you can, and install them on your system. This should help fix the error, if you have Windows Server 2003 or Windows 2000.

The other problem that causes this error is a little more in-depth. The problem is that Windows often gets confused with some of the files & settings it has in its “data pool”. This is the immediate amount of data that your PC keeps within arms-length; and is what your computer uses to help your PC run smoothly (by quickly calling various important pieces of data). The only problem is that most of the time, this data pool becomes damaged & unreadable, causing the Bad Pool Header error to show.

The best way to fix this problem is to use a “registry cleaner” application to repair any of the potentially damaged data inside your PC. A registry cleaner is a software tool that will clean out files from the “registry” of your system, and will fix the various problems that are inside it. The registry is a large database where many of the important settings that Windows needs to read are kept. It’s often the case that this database will become damaged, leading Windows to be unable to process the various pieces of data it requires to run. You can fix this by using a registry cleaner and updating your system.
