Windows Error Codes
Searchable reference for Windows error codes — system errors, BSOD stop codes, NTSTATUS, WMI, RPC, MSI installer, AD/Kerberos, BitLocker, DNS, VPN, Hyper-V, COM/DCOM and more. Each entry includes the hex/decimal value, severity, root causes, and a step-by-step troubleshooting workflow.
How to read a Windows error code
Windows surfaces error codes through Win32, NTSTATUS, HRESULT, and many subsystem-specific spaces. Each code has a hex form (e.g. 0x80070005), a signed decimal form (-2147024891), and a symbolic name (ERROR_ACCESS_DENIED). This page lets you look up any of those forms, see what triggers the code, and follow a vetted troubleshooting workflow tuned for the originating subsystem (Windows Update, BSOD, AD/Kerberos, BitLocker, etc.).
