Answer 2

Hi,

After research, I didn't find information about KB5000802 cause BSOD yet.

Generally, to narrow the issue, we may try to uninstall the KB500802, and check if BSOD still exists.

Please also try to set the dump settings to collect the dump file when BSOD occurs:

How to configure a memory dump:

=========================================

NOTE: If RAM is larger than 32GB, we need to collect Kernel Dump. If the RAM is small than 32GB, we can collect Complete dump. We need to restart the machine to make the setting effect, please arrange downtime first.

1. Set pagefile. (If RAM is larger than 32GB ,set Pagefile to 30GB. If the RAM is small than 32GB, set Pagefile to (RAM+100MB))

a. Right - Click My computer, choose Properties

b. Click the Advanced system Settings.

c. Click the Advanced tab, and then under Performance, click Settings.

d. Click the Advanced tab, and then under Virtual memory, click Change.

e. In the Drive [Volume Label] list, choose one drive with enough disk space, Click Custom size, and then type (RAM+100MB) in both Initial size (MB) and Maximum size (MB) box. Then click Set, click OK.

2. Configure dump type

Locate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl

Set CrashDumpEnabled ; (If RAM is larger than 32GB, set it to 0x2; If the RAM is small than 32GB, set it to 0x1)

Set “Dumpfile = %SystemRoot%\MEMORY.DMP”; (please make sure C drive has enough space, if not, we can change dump to another drive like d:\memory.dmp)

If you collect the dump file for the issue, it's recommended to open a case and upload the dump file with MS for deep troubleshooting:

Below is the link to open a case with MS:

At the same time, I will notice on the forum and check if a huge thread about this issue will arise.

Thanks for your time!
Best Regards,
Anne

Now working.

Answer 4

After the KB5000802 Update, several users reported BSOD (APC.IndexMismatch/win32kfull.sys) when printing to Kyocera printer.
But also system crashes when opening or saving office documents.

After uninstalling KB5000802 everything works fine again.

Answer 5

Yes, the update breaks several printer drivers. Especially Kyocera but also other vendors.

Also can cause Bluescreens when starting specific software. (Probably because this software somehow interacts with printer drivers when you start it.)

There are a lot of very recent reports on different websites/blogs/forums about this. It seems the rollout of the update has been stopped in the meantime.

Uninstalling the update should solve the issues.
