If your computer is facing APC_INDEX_MISMATCH BSoD error, download KB5001567 offline installer and install it to fix the error.
Recently, Microsoft released KB5000802, a Patch Tuesday update for Windows 10 v20H2 and v2004 users. Unfortunately, this update is causing an APC_INDEX_MISMATCH BSoD error in some Windows 10 systems. To be more specific, the KB5000802 causes APC_INDEX_MISMATCH or “win32kfull.sys” errors when the system is connected to a Type 3 printer. Depending on the system configuration, the BSoD error can occur when a Type 3 printer is connected or when you initiate a print job to the Type 3 printer. According to Microsoft all other printer types are safe to use and are not causing any type of errors due to the KB5000802 update.
To fix the problem, Microsoft posted a temporary workaround and earlier this day released another update called KB5001567 to properly and permanently solve the issue. So, if you are getting APC_INDEX_MISMATCH and “win32kfull.sys” errors, I recommend you install the KB5001567 update as soon as possible.
On affected machines, Windows 10 should be able to automatically download and install the update. Alternatively, you can download KB5001567 offline installer and install it manually. This is particularly useful for offline machines that work for dedicated printing.
