rdrleakdiag.exe is a Windows component identified as Microsoft Windows Resource Leak Diagnostic. A documented Windows 10 copy is located at C:WindowsSysWOW64rdrleakdiag.exe and carries Microsoft Windows product metadata and a Microsoft Windows Production PCA 2011 digital signature. That combination is consistent with a legitimate system file. The filename alone is not proof of safety, however: a copy in an unusual folder, an invalid signature, or unexplained memory-dump activity needs investigation. If Windows reports that the file is missing or damaged, use the supported repair sequence—install updates, run DISM, then run System File Checker (SFC)—before considering Windows recovery or reinstall media.
What is rdrleakdiag.exe?
RdrLeakDiag.exe is the executable name for Microsoft Windows Resource Leak Diagnostic. Windows file metadata identifies its product as Microsoft Windows, and ESET operations documentation likewise lists RdrLeakDiag.exe as part of the Microsoft Windows Operating System. The component is associated with diagnostics for resource or memory leaks, rather than with a game, graphics driver, or third-party utility.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A documented Windows 10 build places the file at C:WindowsSysWOW64rdrleakdiag.exe. The presence of that path, Microsoft product metadata, and a valid Microsoft Windows Production PCA 2011 signature together provide meaningful evidence that the binary belongs to Windows. Build-specific file hashes found on reference pages identify only the particular build that was measured; a hash from one release cannot establish that every copy on every edition of Windows is safe.
Windows may start this executable only when a diagnostic task, support workflow, or another system component requests it. Seeing the file in Task Manager briefly is therefore not automatically a problem. The useful question is whether the file is the signed Windows copy and whether its parent process and command line make sense.

Is rdrleakdiag.exe safe?
A signed copy in a Windows system directory is generally consistent with the legitimate Windows diagnostic component. Treat the assessment as conditional, not as a blanket approval based on the filename.
| Check | Consistent with a legitimate copy | Reason to investigate |
|---|---|---|
| Path | C:WindowsSysWOW64rdrleakdiag.exe or another location documented for your Windows build |
A download folder, temporary folder, user profile, game folder, or an unfamiliar drive |
| Digital signature | A valid signature from Microsoft Windows, including Microsoft Windows Production PCA 2011 information where shown | No signature, an invalid signature, or a signer that is not Microsoft |
| Product metadata | Microsoft Windows or Microsoft Windows Operating System | Blank, unrelated, or deliberately misleading product information |
| Execution context | Started by a normal Windows diagnostic or support process with an expected command line | Launched repeatedly by an unknown program, from an unusual parent process, or with unexplained dump-output arguments |
Security monitoring documentation specifically calls attention to starts of rdrleakdiag.exe using -memdmp or fullmemdmp together with output or process parameters. The legitimate tool can create process-memory dumps, so those switches are not automatic proof of malware. They do mean that command-line context matters: an administrator or support technician may have requested a dump, while an unknown process doing so deserves review.

Verify the file in place rather than downloading a replacement or relying on its name. These checks work on supported Windows editions and do not modify the executable.
Check the file location
- Press Ctrl+Shift+Esc to open Task Manager.
- If the process is visible, right-click it and choose Open file location. For a startup warning, note the path shown in the message or use Windows Search to locate the file.
- Compare the path with the documented Windows system location. A path outside a Windows directory is not automatically malicious, but it is not the expected location for the documented copy.
Check Microsoft’s signature
- Right-click the file, select Properties, and open the Digital Signatures tab.
- Select the signature and choose Details. Windows should report that the digital signature is valid and identify Microsoft as the signer.
- Open the certificate details if you need to confirm the certificate chain. An absent or invalid signature means you should not treat the file as an authentic Windows component until the issue is resolved.
Inspect the command line and parent process
In Task Manager, switch to the Details tab, right-click a column heading, choose Select columns, and enable Command line and, where available, Parent process. Record any -memdmp or fullmemdmp switch, the output destination, and the process being dumped. A known support action can explain those arguments; an unknown launcher, a random output folder, or repeated launches without a diagnostic reason should be investigated before you allow the activity to continue.
Do not use a mirror download as a test
Do not replace the file with an executable copied from an EXE or DLL download site. A similarly named file can be modified, compiled for a different Windows build, or bundled with unwanted software. Windows component repair and Microsoft installation or recovery media are the supported ways to restore a missing system file.
Why does Windows report that rdrleakdiag.exe is missing or cannot start?
The message usually indicates that Windows, a scheduled diagnostic, or software configured to call the component cannot find a usable copy. Several conditions can produce the same wording:
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- The file was deleted manually or removed by cleanup or security software.
- An interrupted update or disk error damaged a protected Windows file.
- System-file permissions, the component store, or related registry references are inconsistent.
- A program is calling an old path from a previous Windows build.
- A file with the same name exists outside the Windows directory and is being blocked, quarantined, or rejected because its signature is invalid.
- The startup entry or scheduled task that requests the diagnostic is itself broken, even though the Windows component is intact.
A missing-file popup does not by itself prove an infection, and there is no authoritative published statistic showing how common rdrleakdiag.exe failures or detections are. Diagnose the path and signature first, then repair Windows using its own tools.
How do I fix a missing or corrupt rdrleakdiag.exe file?
Use this order: bring Windows up to date, run DISM from an elevated Command Prompt, run sfc /scannow, and only then move to recovery options. Save work and back up important files before repairs that could restart or reset the system.
1. Install pending Windows updates and restart
- Open Settings and go to Windows Update (on Windows 10, Update & Security, then Windows Update).
- Select Check for updates and install applicable updates.
- Restart when prompted. If the computer is unstable, close applications and copy important documents to another drive before restarting.
Updating first prevents you from repairing an older component version that Windows is about to replace. If the error began immediately after an update, note the update date; that information helps you choose between System Restore and a reinstall if later steps fail.
2. Run DISM with administrator rights
- Open Start, type Command Prompt, right-click it, and choose Run as administrator. Approve the User Account Control prompt.
- Enter this command exactly:
DISM.exe /Online /Cleanup-image /RestorehealthPress Enter and wait for the operation to finish. It can pause for an extended period while Windows checks and repairs the component store. Do not close the window because the percentage appears unchanged.

3. Run System File Checker after DISM
In the same elevated Command Prompt, run:
sfc /scannowMicrosoft describes SFC as a Windows tool that checks system files for corruption and helps fix problems that may cause Windows to malfunction. DISM is run first because SFC uses the component store as a source for healthy replacement files.
4. Read the result and restart
- Windows Resource Protection did not find any integrity violations: SFC found no corruption in the protected files it checked. If the popup remains, the caller may be using a stale path or a broken startup task rather than a damaged system file.
- Windows Resource Protection found corrupt files and successfully repaired them: Restart and test the action that produced the error.
- Windows Resource Protection found corrupt files but was unable to fix some of them: Do not repeat the command indefinitely. Review the CBS log for details, restart, and continue to the supported recovery choices below if the error persists.
- DISM cannot complete: Record the exact error number and text. A damaged component store, insufficient disk space, servicing problem, or unavailable repair source may require recovery media.
What should I do if DISM and SFC do not fix the error?
Escalate through Windows recovery instead of copying an unknown executable into the system directory. Choose the least disruptive option that matches your backup situation and the severity of the failure.
Try System Restore when the problem is recent
System Restore can roll system files and settings back to an earlier restore point without intentionally removing personal documents. Open Control Panel, search for Recovery, select Open System Restore, and choose a point created before the first rdrleakdiag.exe error. Review the affected-program list before confirming; applications or drivers installed after that point may need to be reinstalled.
Use installation or recovery media
Microsoft lists Windows installation media and recovery media as supported options when the installed system cannot repair itself. Create or use legitimate media for the correct Windows edition and architecture, boot from it, and select the repair tools before choosing a full installation. If you perform a reinstall, verify activation and back up data first; a clean installation can remove applications and personal files.
Reinstall the current Windows version
An in-place reinstall can refresh Windows system components while preserving personal files and, in many cases, applications, provided you select the keep-files option offered for your edition. Follow the on-screen compatibility and backup checks, and keep the computer connected to power throughout the process.
Reset this PC only when necessary
Reset this PC is more disruptive. Windows offers choices that keep personal files or remove everything, but applications and settings are affected. Use it after backups and after less disruptive recovery paths have failed, especially if the file is missing across multiple user accounts or Windows cannot boot normally.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Should I delete rdrleakdiag.exe?
Do not delete a valid, signed copy from a Windows system directory. Removing a protected component can create new servicing failures and will not repair the program or task that called it. If you find an unsigned copy in an unrelated folder, first preserve its path, signature details, parent process, and command line; then use your organization’s security procedures or a reputable antivirus investigation rather than deleting evidence blindly.
If a security product quarantined the file, do not restore it solely because the filename looks familiar. Confirm whether the quarantine record points to the documented Windows path and whether the remaining system copy is signed. DISM and SFC can restore a damaged protected file without trusting a downloaded replacement.

How should I handle rdrleakdiag.exe when it appears during a game crash?
The executable is a Windows diagnostic component, not a game runtime or graphics driver. If it appears at the same time as a game crash, capture the timestamp, path, command line, and parent process, then check Windows Event Viewer for entries at that time. A memory dump may have been requested to diagnose another process; deleting the diagnostic file will not fix the game’s underlying fault.
For a game-specific failure, update the game and its official graphics, audio, or chipset drivers separately, and keep those changes distinct from the Windows component repair above. If the popup occurs at every boot even when no diagnostic is running, inspect startup apps and Task Scheduler for a stale reference after confirming that the Windows copy itself is healthy.
Which situation am I dealing with?
| Situation | Most likely interpretation | Next action |
|---|---|---|
| Signed file in the Windows system directory; no unusual activity | Normal Windows component | Leave it in place. Investigate only if an application reports a separate error. |
| File in an unexpected folder or with an invalid signature | Impersonating, modified, or unrelated executable | Do not run or replace it. Record evidence and perform a security investigation. |
| Expected path, but Windows says the file is missing or corrupt | Damaged, deleted, or incompletely serviced Windows component | Install updates, run DISM, then SFC; read the result. |
| DISM/SFC cannot repair the component | Deeper servicing or installation damage | Back up data and use System Restore, recovery media, an in-place reinstall, or Reset this PC as appropriate. |
Repeated -memdmp or fullmemdmp launches from an unknown parent |
Unexplained process-memory dump activity | Investigate the parent process, output path, account, and security logs before allowing further launches. |

Frequently Asked Questions
Can rdrleakdiag.exe read my game saves or personal documents?
The filename identifies a diagnostic executable, not a data format or game service. Whether any process accesses a file depends on the diagnostic request and the process being examined, so review the parent process, command line, and output location if you see unexpected activity.
Why does a missing-file popup appear after I uninstall a program?
An uninstaller can leave behind a startup entry or scheduled task that still points to a Windows component. If DISM and SFC report no corruption, inspect recently removed software, Startup apps, and Task Scheduler for that stale reference instead of downloading a replacement executable.
Can I verify the signature without opening the file?
Yes. File Explorer’s Properties dialog exposes the Digital Signatures tab without launching the program. You can also record the signer and certificate status for your administrator or security team before taking any action.
Does every Windows 10 or Windows 11 computer have rdrleakdiag.exe?
The available documentation ties the filename and path to particular Windows builds, not to a universal file list for every edition and release. Absence alone is therefore not proof of damage; compare your build, installed components, and the event that requested the file before repairing Windows.
