# Azure Windows VM displays bug check 0x0000001E - KMODE_EXCEPTION_NOT_HANDLED
12+
13+
**Applies to:** :heavy_check_mark: Windows VMs
14+
15+
This article helps you resolve an issue where a Microsoft Azure virtual machine (VM) experiences the **KMODE_EXCEPTION_NOT_HANDLED** bug check with the stop code 0x0000001E.
16+
17+
## Symptoms
18+
19+
When you use [Boot diagnostics](./boot-diagnostics.md) to view the screenshot of a VM, the Windows operating system (OS) displays the **KMODE_EXCEPTION_NOT_HANDLED** bug check (0x0000001E).

22+
23+
## Cause
24+
25+
This indicates that a kernel-mode program generated an exception that the error handler didn't catch. To interpret it, you must identify which exception was generated with a memory dump.
26+
27+
## Collect a memory dump for troubleshooting
28+
29+
If you experience this issue, [collect an OS memory dump file](./collect-os-memory-dump-file.md) and then [create a support request](https://ms.portal.azure.com/#blade/Microsoft_Azure_Support/HelpAndSupportBlade/overview?DMC=troubleshoot) for Azure support to troubleshoot and diagnose the issue.
