BAD_POOL_CALLER Blue Screen on Windows 11

Windows may be a very easy-to-use and a stable operating system, but at times you may find it throwing up errors. These are Stop Errors or Blue Screens. One of the frequently encountered Stop Errors is – BAD_POOL_CALLER with a value of 0x000000C2. In this article, we will share some information about this error, cause, and some suggestions to fix BAD POOL CALLER error in Windows 11.

Before getting into the solution, you should know the reason of this issue.

This particular problem occurs when a program tries to use a processor thread that doesn’t exist or is currently unavailable. Typically, this is at a bad IRQL level or due to double-freeing the same memory allocation. Also, if the same processor thread is being used by another program, it can cause the error. In other words, if a bad pool request has been made by a thread in the processor, you can get the BAD_POOL_CALLER stop error displayed on your screen.

When this happens, Windows takes quick action on such error codes. Your Windows computer restarts itself and runs a chkdsk test to protect the data from being damaged. Sometimes, it solves the issue, but it may not be helpful in all cases.

If you cannot do either, then you may then have to boot into Windows 11/10 with your Windows Installation Media or Recovery Drive and select Repair your computer to enter Troubleshoot > Advanced Startup Options.
