Microsoft is rolling out emergency updates to fix the Blue Screen of Death “APC_INDEX_MISMATCH” and “win32kfull.sys” issues. You may recall that Windows 10 received security updates on the March 2021 Patch Tuesday that were packed with several fixes. While the previous Windows 10 cumulative update solved intended Windows 10 problems, the updates brought other issues that lead to BlueScreen errors with the error code APC_INDEX_MISMATCH while attempting to print any document.
To mitigate this problem, Christopher Leung (Microsoft Employee) offered a workaround and after working on these issues, Microsoft released out-of-band updates.
