What is 0x0000070C?
0x0000070C is a Windows system error returned by the Win32 API. It is defined in the MS-ERREF reference under the standard HRESULT / Win32 mapping rules. In plain terms, the specified data type is invalid. Because the same numeric value can be raised by any API that returns Win32 status, the exact trigger depends on which call returned it; the symbolic name is the best clue.
The numeric value 0x0000070C maps to the symbolic name ERROR_INVALID_DATATYPE. Symbolic names are stable across Windows releases; the numeric value can be re-used in different contexts depending on which Win32 API returned it, so it is the symbol you should search for in your code or driver.
When does 0x0000070C appear?
ERROR_INVALID_DATATYPE is most often reported in these scenarios. They are listed in roughly the order I see them in real incidents on Windows Server and Windows 10/11 clients:
- The calling application passed an unexpected argument to a Win32 API and the runtime returned this status.
- A required Windows service or driver is in the wrong state.
- A recent Windows update changed the behaviour of the API that now returns this code.
- A permission or token mismatch made the call fail.
- A resource limit (handle count, memory, disk) was hit.
- A configuration file or registry value the API depends on is missing or malformed.
The official message , _"The specified data type is invalid."_ , is deliberately short. Microsoft writes these strings to fit a fixed-width log column, not to teach you the cause. Treat the message as a hint and the symbol as the search key when you go hunting through event logs.
How to fix 0x0000070C
Pick the path that matches how you got the error. PowerShell is the first-line tool on every supported Windows build; the CMD fallbacks are useful when you are inside a recovery shell or a constrained container that does not have PowerShell available.
Windows fix (PowerShell, run as Administrator)
# Show the full event around the time the error appeared.
Get-WinEvent -LogName System,Application -MaxEvents 100 |
Sort-Object TimeCreated -Descending |
Format-Table TimeCreated, ProviderName, Id, LevelDisplayName -AutoSize
# Capture the next occurrence into an .evtx for support.
wevtutil epl System C:\Temp\system-snapshot.evtx
# Run the standard health checks on the OS files.
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
Windows fix (CMD)
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
wevtutil qe System /c:20 /f:text /rd:true
Event log snapshot (always worth capturing first)
# Pull the last 50 System and Application events that mention 0x0000070C
# or its symbolic name ERROR_INVALID_DATATYPE to get exact context.
Get-WinEvent -LogName System,Application -MaxEvents 200 |
Where-Object { $_.Message -match '0x0000070C' -or $_.Message -match 'ERROR_INVALID_DATATYPE' } |
Select-Object TimeCreated, ProviderName, Id, Message |
Format-List
If you cannot fix it immediately
Roll back the change that triggered the error if you can identify it. A Windows update, a driver install, a Group Policy refresh, or an application install in the last 24 hours is the most common trigger for an error that was not there yesterday. Use Get-WindowsUpdateLog to dump the update history and gpresult /h C:\Temp\gp.html to capture the current Group Policy set. Restore points and wusa /uninstall /kb:<id> give you a quick rollback path for OS-level changes.
How to verify the fix worked
After applying any change, re-run the original action that produced the error and confirm the call returns success. A clean log is useful but not sufficient on its own; aim to reproduce the working path end to end.
# 1. Re-run the failing action.
# 2. Tail the relevant log for new occurrences of 0x0000070C.
Get-WinEvent -LogName System -MaxEvents 50 |
Where-Object { $_.Message -match '0x0000070C' } |
Format-Table TimeCreated, Id, Message -AutoSize
# 3. Confirm no new entries appeared after your fix timestamp.
$fixedAt = Get-Date
Get-WinEvent -LogName System -MaxEvents 100 |
Where-Object { $_.TimeCreated -gt $fixedAt -and $_.Message -match '0x0000070C' }
If the verification command returns rows, the underlying cause is still in play and you should treat the change as not yet complete. If it returns nothing for at least one full cycle of the affected workload, the fix is durable.
Frequently asked questions
What does 0x0000070C mean exactly?
It is the Windows status value 0x0000070C (decimal 1804), symbolic name ERROR_INVALID_DATATYPE. In plain terms, the specified data type is invalid. It is defined in the Microsoft Win32 system error codes reference.
Is 0x0000070C dangerous?
This is a status signal in most cases, not a breach indicator. It is a status value, not a security event. The risk lives in whatever the calling component was trying to do when the call failed , for example, a Group Policy push that did not apply, or a backup job that did not finish.
Will reinstalling Windows fix 0x0000070C?
Usually no. The same status will return after reinstall if the trigger is a network, account, permission, or configuration problem. Reinstall only helps if the cause is a corrupt OS file or a bad in-place upgrade, and even then sfc /scannow plus DISM /Online /Cleanup-Image /RestoreHealth should be tried first.
Can a Windows Update fix 0x0000070C?
Sometimes. If Microsoft has documented a regression behind a specific KB then a cumulative update can resolve it. Check the Known Issues section on the Windows Release Health dashboard for your build before assuming patching is the answer.
How is 0x0000070C different from neighbouring codes?
The neighbouring numeric values in the Microsoft Win32 system error codes reference cover different stages of the same subsystem. The symbol ERROR_INVALID_DATATYPE is the precise identifier , search for the symbol, not the number, when comparing causes.

Field notes from real Windows incidents
When I work on the 0x0000070C symptom the rhythm I lean on is the one I have built over years of these tickets. STOP codes look terrifying but the first DWORD almost always points directly at the responsible driver. Windows error codes come in a handful of families; once you recognise the family, the doc page is one search away. Reliability Monitor is the single most underused triage surface in Windows — it gives 30 days of crash history without writing a query.
Tools I actually reach for
For the 0x0000070C symptom on Windows the cheapest signal I can land usually comes from Windows Performance Recorder, then Event Viewer (eventvwr.msc), Windows Error Lookup Tool (err.exe), Reliability Monitor (perfmon /rel) when Windows Performance Recorder cannot see the layer the fault sits in, and PowerShell Get-WinEvent for the cases where neither of those answers cleanly. That ordering is not academic. It matches the layers the failure tends to surface through, so the cheap signal lands first and the heavier tooling only comes out when the simpler answer does not hold up under scrutiny.
Verification I run before I close the ticket
Before I mark the 0x0000070C symptom resolved on a Windows unit, the verification loop below is what I actually run. Each step proves a different layer is green, and the order matters - the cheap checks gate the more expensive ones.
wevtutil epl System system.evtx # export for offline reviewIf that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.
err.exe 0xXXXXXXXX # symbolic decodeIf that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.
sfc /scannowIf that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.
Get-WinEvent -FilterHashtable @{LogName='System'; Level=1,2; StartTime=(Get-Date).AddDays(-7)}If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.
DISM /Online /Cleanup-Image /RestoreHealthOnly when every line above runs clean do I close the ticket and update the runbook with the timestamps.
Where I check first when the docs disagree
When two sources contradict each other on a Windows detail, the disambiguation order I lean on is stable. I usually start at github.com/microsoft/Windows-Driver-Frameworks for the ground-truth view on Windows. I usually start at support.microsoft.com for the ground-truth view on Windows. I usually start at techcommunity.microsoft.com/category/windows for the ground-truth view on Windows. Random blog posts and reseller wikis are signal, not ground truth, and I treat them as such until the references above either confirm or contradict the claim.
Pitfalls I have walked into on this exact path
The shortcuts that look smart on the 0x0000070C symptom have a habit of biting back. The pitfalls below are the ones I have personally walked into on a Windows unit, not things I read about. STOP codes look terrifying but the first DWORD almost always points directly at the responsible driver. Windows error codes come in a handful of families; once you recognise the family, the doc page is one search away. When in doubt I revert to the slower path that the manual prescribes - the time I save by skipping it is always smaller than the time I spend cleaning up afterwards.
What I tell the next on-call
When I hand the 0x0000070C symptom off to the next person on rotation, the three lines I leave in the runbook are these. First, the symptom signature for Windows on the Windows family - not a paraphrase, the exact string that surfaces. Second, the diagnostic that gave the highest signal in the least time. Third, the exact verification command whose green output justified closing the ticket. That trio is what turns a one-off fix into a runbook entry the next engineer can use without paging me at three in the morning.
I also add a one-line note on the cost of getting this wrong. For the 0x0000070C symptom on a Windows unit, the cost is rarely the replacement part. It is the downtime, the second site visit, and the trust deficit you spend with whoever owns the asset when the fix does not hold. That framing keeps the next on-call from choosing the cheap-looking shortcut that ends up costing the most in elapsed hours and goodwill.
