Windows build number

10.0.26100.3775

Other Software

No response

Steps to reproduce

Clean install Windows 11 24H2 (Build 26100.3775)

Install latest Windows Terminal from Microsoft Store

Launch Windows Terminal

Crash occurs immediately with Application Error event 1000

Error Details​​:

Faulting module: C:\WINDOWS\WinSxS\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.9635_none_08e2c157a83ed5da\MSVCR90.dll
Exception: 0xC0000005 (Access Violation) at offset 0x0000000000019353

Expected Behavior

Windows Terminal should use the modern VC++ runtime (vcruntime140.dll) that ships with Windows 11, not the legacy VC++ 2008 runtime.

Actual Behavior

it uses C:\Windows\WinSxS\amd64_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.9635_none_08e2c157a83ed5da\MSVCR90.dll

@DHowett commented on GitHub (May 11, 2025):

The VC++ 2008 runtime is being loaded by the SyncDisk software. Please take this up with the vendor of that software.

In truth, Windows Terminal does not load a C++ runtime DLL. It statically links the C++ runtime and dynamically links the C runtime.
