What Is Apc Index Mismatch Windows 10 Error?

Sometimes, a little bit of knowledge can be helpful to fix the big issue. In this regard, I am sharing a brief knowledge about APC index mismatch windows 10. According to Microsoft, in the windows operating system, An asynchronous procedure call (APC) is a function that executes asynchronously in the context of a particular thread. The system can generate APCs (kernel-mode APCs) or an application (user mode APCs).

There is an APC index in the Windows operating system, which ensures the proper functioning of the computer. But when a significant problem of a computer’s software or hardware arises, the APC index mismatches windows 10 happen. This error shows an irregularity in performing the number of processes during entering and exiting in an area of operations.

For various processes, the blue screen of death issue incurred and crashed a computer. Ultimately, the operating system warns that if you run the soft run software, there is a significant risk of damaging the machine.

What Causes Apc Index Mismatch Windows 10?

A particular problem’s solution may hide in its causes. So, if we can find out the reason, it will be a less time-consuming way to fix the issue. In these circumstances, let’s know the causes of the APC index mismatch windows 10 matter. There is three identified reason what patronize the APC index mismatch windows 10. It is not essential to have all issues at a single time. So, the reasons that cause the APC index mismatch windows 10 are below.

Hardware Incompatibility Issues.

A computer consists of some hardware, which must be compatible with the operating system. But sometimes, the hardware may not be compatible with calibrating with each other. On the other hand, in the case of installing new hardware, it may not be compatible with the installed version of Windows. There are some minimum system requirements for windows 10. It would be best if you had Processor: 1 gigahertz (GHz) or faster, RAM: 1 gigabyte (GB) for 32-bit or 2 GB for 64-bit, Graphics card: Compatible with DirectX 9 or later with WDDM 1.0 driver, Hard drive size: 32GB or larger hard disk, and Display: 800×600. When the hardware requirements for installing windows 10 do not match, it provokes the APC index mismatch windows 10, which causes a BSOD error.

Changing Corrupting and Damage Of The System Files.

System files are vitally crucial for running an operating system and a computer. But due to various reasons, the system files may be changed, corrupt, or missing. Especially in the case of APC index mismatch windows 10, the Igdkmd64.sys file may be corrupted or altered, and the APC index mismatch windows 10 problem occurs. In addition to this, some other system files like; ntoskrnl.exe fltmgr.sys, win32k.sys wdf01000.sys can be changed or missed and prompt the APC index mismatch windows 10, which can cause the blue screen of a dead issue.

Incompatibility Of The Device Driver.

Drivers play a vital role in smooth running and using the full features. But sometimes, the device drivers can be the reason for various problems. And in the APC index mismatch windows 10 bluescreen error, there is a positive correlation with the driver’s issue. Suppose one or more device driver is backdated, corrupted, or damaged. In that case, it also affects the system files, leading to the APC index mismatch windows 10 issue.

Most importantly, when the problem shows up with an error code of 0x00000001, this means there is a problem with the device drivers. By the report of the many users, it seems that graphics drivers like Nvidia sound drivers like Realtek can incur the issue. Moreover, the Printer driver, which uses Type 3 drivers, causes a mismatch in the asynchronous procedure calls (APC) state index.

Problematic Software.

We know very well that, without software, we cannot run a computer. But sometimes software can also cause various problems for a different reasons. In the issue of APC index mismatch Windows 10, the software may be responsible and initiate the bluescreen of a dead issue.

Two kinds of software can be involved. One is Windows itself, and the other one is third-party software. The windows updates can cause the APC index mismatch windows 10 issue. Especially for KB5000802 association with 2004/20H2 Windows versions after the first quarter of 2021. After installing this update, an overwhelming majority of the Windows users encountered the APC index mismatch windows 10 issue. And suffer from the blue screen of death problem while they want to print something. Besides, some third-party software is also responsible for occurring the APC index mismatch windows 10 trouble.

Enable Virtualization features in BIOS.

There is an option to use our computer as a virtual machine. To use the feature, we must enable the machine virtualization at BIOS. Some Windows users report a BSOD crash that derives from the APC index mismatch windows 10 problem after enabling the virtualization.

The above are the leading identified causes of the APC index mismatch windows 10, which occurs the blue screen of death (BSOD) while using the computer. But what is the reason it is, we should get rid of the problem. So, let’s get into the business point of solving the APC index mismatch windows 10 issue.
