What is 0xC00002B5?
0xC00002B5 is a Windows NTSTATUS value returned by the kernel or by a driver running in kernel mode. NTSTATUS codes are 32-bit values that the user-mode layer normally converts to a Win32 error before showing it, but tools that call into the native API directly (debuggers, kernel tracers, file-system filter drivers) surface the raw status. In plain English, this code says: float multiple traps. The official reference describes it like this: "Multiple floating-point traps.". That description is the contract; the actual fix depends on which subsystem produced the value, which is what the rest of this guide walks through.
When does 0xC00002B5 appear?
The same status code can come from very different code paths. Here are the scenarios I see most often when STATUS_FLOAT_MULTIPLE_TRAPS shows up on a real machine:
- Native code in an installed application triggers a floating-point operation that the CPU traps.
- A scientific or finance app loads a binary built for a different CPU feature level (AVX, SSE) than the host.
- An emulator (BlueStacks, NoxPlayer, qemu) translates an instruction that the host floating-point unit cannot satisfy.
- A misaligned data load in a poorly-written native DLL faults on architectures that do not allow unaligned access.
If your environment matches more than one of these, work the fix steps in order: cheap diagnostics first, system repair second, in-place reinstall as the last resort.
How to fix 0xC00002B5
Run an elevated PowerShell prompt (right-click Start, then Windows Terminal (Admin) or PowerShell (Admin)). Each block below is a copy-paste recipe; adapt the placeholders in angle brackets to your environment before running.
Capture the faulting process with Windows Error Reporting (PowerShell, run as administrator)
Get-WinEvent -LogName Application -MaxEvents 50 | Where-Object { $_.Id -in 1000,1001,1026 } | Format-Table TimeCreated, ProviderName, Message -AutoSize
Get-ChildItem 'C:\ProgramData\Microsoft\Windows\WER\ReportArchive' | Sort-Object LastWriteTime -Descending | Select-Object -First 5
Check the CPU feature set the binary expects (PowerShell, run as administrator)
Get-CimInstance Win32_Processor | Select-Object Name, Manufacturer, NumberOfCores, MaxClockSpeed
wmic cpu get caption,deviceid,name,numberofcores,maxclockspeed,status
Reinstall the application with the build that matches your CPU class (PowerShell, run as administrator)
Get-WmiObject -Class Win32_Product -Filter "Name LIKE '%<app>%'" | ForEach-Object { $_.Uninstall() }
# Then install the vendor-supplied package that targets your CPU generation.
CMD fallback (run as administrator)
wmic cpu get caption,deviceid,name,numberofcores,maxclockspeed,status
sfc /scannow
Pull the matching event-log entry
$code = '0xC00002B5'
Get-WinEvent -LogName System -MaxEvents 1000 | Where-Object { $_.Message -match $code } | Select-Object -First 10 TimeCreated, Id, ProviderName, Message | Format-List
Get-WinEvent -LogName Application -MaxEvents 1000 | Where-Object { $_.Message -match $code } | Select-Object -First 10 TimeCreated, Id, ProviderName, Message | Format-List
Back the registry up before any edit
$stamp = Get-Date -Format yyyyMMdd-HHmm
New-Item -ItemType Directory -Force -Path 'C:\Backup' | Out-Null
reg export 'HKLM\SOFTWARE' "C:\Backup\HKLM-Software-pre-windows-error-0xc00002b5-$stamp.reg" /y
reg export 'HKLM\SYSTEM' "C:\Backup\HKLM-System-pre-windows-error-0xc00002b5-$stamp.reg" /y
If you can't fix immediately
Reduce the blast radius until the change window opens: stop the service that raises the error, isolate the host from production traffic, or fall back to a known-good snapshot. A short workaround beats a rushed change on a Friday night.
# Pause the affected service and capture state before changing anything.
Get-Service | Where-Object Status -eq 'Running' | Where-Object Name -match '<service-keyword>' | Stop-Service -Force -PassThru
Get-ScheduledTask | Where-Object State -ne 'Disabled' | Where-Object TaskName -match '<task-keyword>' | Disable-ScheduledTask
How to verify the fix worked
Work through these checks in order. If any one fails, repeat the matching fix step before moving on.
- Re-launch the affected application and reach the workflow that crashed; no Application Error event should land.
- Get-WinEvent -LogName Application against EventID 1000 should not show the app for at least the next session.
- If you reinstalled with a different CPU build, confirm via Get-Item .\app.exe | Get-AuthenticodeSignature that the binary matches the vendor's package.
Frequently asked questions
What does 0xC00002B5 mean exactly?
The Windows documentation defines it as a ntstatus that signals float multiple traps. In day-to-day terms, it is the operating system telling a calling program that the request cannot complete in the current state. The fix is almost always about restoring the state the caller expected, not about removing the code itself.
Is 0xC00002B5 dangerous?
This is a status signal in most cases, not a breach indicator. The status code is a symptom, not the disease. The danger is in what produced it: a corrupted driver, a flaky disk, an exhausted resource, or a permission boundary that is wrong. Read the event-log context around the code before assuming the worst.
Will reinstalling Windows fix it?
Usually no, and it is the wrong first move. A clean install removes the entire configuration that produced the error, which makes it look fixed for a few days while you reinstall apps and drivers. The same condition tends to come back the moment the original workload is restored. Work the fix steps above before you reach for the install media.
What is the difference between 0xC00002B5 and the symbolic name STATUS_FLOAT_MULTIPLE_TRAPS?
They are the same value. 0xC00002B5 is the numeric form a developer prints, and STATUS_FLOAT_MULTIPLE_TRAPS is the C/C++ constant defined in the Windows headers. Tooling that consumes one will accept the other; the lookup is deterministic.
Where can I look up other NTSTATUS codes?
Microsoft maintains the full reference at MS-ERREF. For Win32 error names there is the System Error Codes index. Both are searchable by hex value and by the symbolic name.

Field notes from real Windows incidents
When I work on the 0xC00002B5 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. Reliability Monitor is the single most underused triage surface in Windows — it gives 30 days of crash history without writing a query. Windows error codes come in a handful of families; once you recognise the family, the doc page is one search away.
Tools I actually reach for
For the 0xC00002B5 symptom on Windows the cheapest signal I can land usually comes from DISM and sfc, then PowerShell Get-WinEvent, WinDbg for STOP code analysis, Windows Error Lookup Tool (err.exe) when DISM and sfc cannot see the layer the fault sits in, and Reliability Monitor (perfmon /rel) 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 0xC00002B5 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.
DISM /Online /Cleanup-Image /RestoreHealthIf 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.
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.
Get-WinEvent -FilterHashtable @{LogName='System'; Level=1,2; StartTime=(Get-Date).AddDays(-7)}Only 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 learn.microsoft.com/windows/win32/debug/system-error-codes 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. I usually start at github.com/microsoft/Windows-Driver-Frameworks 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 0xC00002B5 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. Windows error codes come in a handful of families; once you recognise the family, the doc page is one search away. DISM RestoreHealth needs network or a known-good source image; the most common cause of a failed RestoreHealth is a blocked Windows Update endpoint. Reliability Monitor is the single most underused triage surface in Windows — it gives 30 days of crash history without writing a query. 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 0xC00002B5 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 0xC00002B5 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.
