Fix Windows Registry Errors    |    STOP 0x0000001A    |    Repair Windows Error 0x0000001A


STOP Errors are usually the result of a hardware malfunction or device driver issue. It is also possible to receive a Blue Screen Error due to bad system memory, malfunctioning power supply, components overheating, or hardware overclocked beyond its specification. In older versions of the Windows OS you may also receive Blue Screen Errors due to incompatible DLL files.

Since the only option when receiving a Blue Screen Error is to reboot, any unsaved data is lost. With that in mind, it is very important to eliminate these errors to protect your data.

The MEMORY_MANAGEMENT stop error code has a value of 0x0000001A. This indicates that a severe memory management error occurred.


The following parameters are displayed on the blue screen. Parameter 1 is the only parameter of interest; this identifies the exact violation.

Parameter 1Cause of Error
0x1The fork clone block reference count is corrupt. (This only occurs on checked builds of Windows.)
0x777The caller is unlocking a system cache address that is not currently locked. (This address was either never mapped or is being unlocked twice.)
0x778The system is using the very last system cache view address, instead of preserving it.
The PTEs mapping the argument system cache view have been corrupted.
0x1000A caller of MmGetSystemAddressForMdl* tried to map a fully-cached physical page as non-cached. This action would cause a conflicting hardware translation buffer entry, and so it was refused by the operating system. Since the caller specified "stop error code on failure" in the requesting MDL, the system had no choice but to issue a stop error code in this instance.
0x1010The caller is unlocking a pageable section that is not currently locked. (This section was either never locked or is being unlocked twice.)
0x1234The caller is trying lock a nonexistent pageable section.
0x1235The caller is trying to protect an MDL with an invalid mapping.
0x3451The PTEs of a kernel thread stack that has been swapped out are corrupted.
Internal memory management structures are corrupted.
0x41283The working set index encoded in the PTE is corrupted.
0x41284A PTE or the working set list is corrupted.
0x41286The caller is trying to free an invalid pool address.
0x41785The working set list is corrupted.
0x41287Internal memory management structures are corrupted. To further investigate the cause, a kernel memory dump file is needed.
0x61940A PDE has been unexpectedly invalidated.
0x03030303The boot loader is broken. (This value applies only to Intel Itanium machines.)
OtherAn unknown memory management error occurred.
