0X800702D5

The CPUs in this multiprocessor system are not all the same revision level. To use all processors the operating system restricts itself to the features of the least capable processor in the system. Should problems occur with this system, contact the CPU manufacturer to see if this mix of processors is supported

Overview

0X800702D5 wraps Win32 result 725 (0x2D5) through FACILITY_WIN32 (7). The code identifies the failure condition, while the calling program, timestamp, logs, and repeatable operation identify the responsible component.

Common causes

  • The affected operation returned the official ERROR_MP_PROCESSOR_MISMATCH condition
  • The calling program encountered the documented result: The CPUs in this multiprocessor system are not all the same revision level. To use all processors the operating system restricts itself to the features of the least capable processor in the system. Should problems occur with this system, contact the CPU manufacturer to see if this mix of processors is supported.
  • A configuration, resource, or dependency used by the applications and processes operation did not meet its requirements
  • A recent program, service, installer, or system change altered the context in which 0X800702D5 occurs

Symptoms

  • Confirm which program or Windows operation returned 0x800702d5
  • Match the timestamp to Application and System event records
  • Retest the same operation and preserve any changed result code

Prevention

  • Preserve Application and System events that accompany 0X800702D5
  • Use supported installers and configuration methods for the affected applications and processes workflow
  • Document changes so the operating context for ERROR_MP_PROCESSOR_MISMATCH can be reconstructed

How to troubleshoot error 0X800702D5

Use these Windows-native steps in order. Stop when Windows Update works again; advanced repair commands are not necessary on every PC.

1

Restart Windows and retry the update

Save your work, restart the PC, then open Settings > Windows Update and select Check for updates. A restart can release pending files without changing Windows configuration.

2

Run the Windows Update troubleshooter

Open Settings > System > Troubleshoot > Other troubleshooters. Locate Windows Update and select Run. Current Windows 11 versions may continue the diagnostic flow in Get Help.

3

Repair Windows components when indicated

If troubleshooting still reports missing or damaged components, open Terminal as administrator, run DISM RestoreHealth, and then run System File Checker. Do not interrupt either scan.

Before advanced repair: Back up important files. Managed work or school PCs may use organization update policies, so contact the administrator before changing services or update components.

Official-source grounding

The error meaning is grounded in Microsoft System Error Codes (WinError.h). The visual sequence also follows Microsoft Support guidance for Windows Update troubleshooting and Microsoft DISM repair guidance. Causes and repair steps vary by system evidence; this report does not claim a universal success rate.

Frequently asked questions

What does 0X800702D5 mean?

Microsoft defines 0X800702D5 as ERROR_MP_PROCESSOR_MISMATCH: The CPUs in this multiprocessor system are not all the same revision level. To use all processors the operating system restricts itself to the features of the least capable processor in the system. Should problems occur with this system, contact the CPU manufacturer to see if this mix of processors is supported. 0X800702D5 wraps Win32 result 725 (0x2D5) through FACILITY_WIN32 (7). The code identifies the failure condition, while the calling program, timestamp, logs, and repeatable operation identify the responsible component.

Is 0X800702D5 always caused by the same problem?

No. The code identifies a failure condition, but the exact cause depends on the affected operation, Windows build, logs, and recent system changes.

Can Advanced System Repair help with 0X800702D5?

Advanced System Repair can scan for damaged Windows components and related system issues. No tool can guarantee one universal fix; preserve backups and match repair steps to the evidence on the affected PC.
