StorDiag.exe: new Windows 10 Storage Diagnostic tool

StorDiag.exe is a new command line drive tool to analyze storage on devices running Windows 10 that Microsoft added silently to the Anniversary Update.
The program is a diagnostic tool that you may use to identify storage related issues. Issues that it may detect including corruption of the NTFS file system.
There is more to the program than that though. You may use it to run a an ETW trace as well, and check the logs, Registry files and event files StorDiag.exe creates when it is done with the processing.
The application runs several tools in the background for that, including CheckDisk, fsutil and fltmc.
Using StorDiag.exe
The application can only be run from an elevated command prompt. Since it is only available in Windows 10's Anniversary Edition, instructions are only provided for this particular version of Windows.
Step 1: Open an elevated command prompt
First thing you need to do is open an elevated command prompt.
- Tap on the Windows-key, type cmd.exe, hold down the Ctrl and Shift keys, and hammer on the Return key.
- Confirm the UAC prompt that is displayed afterwards.
- The elevated command prompt window should open. If it reads Administrator in the title, all is well.
Step 2: The command
The program supports three parameters that you can run it with. You may run stordiag.exe /? first to display them on the screen.
Collects storage and filesystem diagnostic logs and outputs them to a folder.
StorDiag [-collectEtw] [-out <PATH>]
-collectEtw Collect a 30-second long ETW trace if run from an elevated session
-collectPerf Collect disk performance counters
-checkFSConsistency Checks for the consistency of the NTFS file system
-diagnostic outputs a storage diagnostic report
-bootdiag output boot sectors of the disk
-driverdiag output avaliable storport and storahci logs
-out <PATH> Specify the output path. If not specified, logs are saved to %TEMP%\StorDiag
Step 3: Running storage diagnostics
You may run the application with all commands, or only some of them.
If you want to run them all, use the following command to do so:
stordiag.exe -collectEtw -checkFSConsistency -out c:\users\martin\desktop
Note: You need to change "martin" in the out path to the username on your system. You may also leave the -out path part. If you do, all logs are saved to a StorDiag folder on the system's temp folder. Simply copy and paste %TEMP%\StorDiag in the Explorer address bar and the location should open.
The processing takes a couple of minutes tops. It depends largely on the number of storage devices connected to the Windows 10 machine at the time.
The program will check all drives for corruption using CheckDisk, and will collect a 30 second ETW trace. It runs several tools in the background and logs their output.
You find the massive list of log files and event files in the -out directory afterwards.

The CheckDisk information about each drive and potential corruption are probably most useful to users of the operating system.
System administrators find lots of information in the other files that they may use to analyze storage related issues.
StorDiag.exe does not resolve any of the issues that it may report. It is up to you or the system administrator to correct those.


What mental age of reader are you targeting with the first sentence? 10?
Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.
If your paymaster Microsoft permits it, of course.
5. Rufus
6. Ventoy
PS. I hate reading these “SEO optimized” articles.
I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.
bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.
ps…. time travelling?

Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.
I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:
1) Too young to remember a time before W10 and W11 (doesn’t know better)
2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)
3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””
4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows
5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss
Obviously that doesn’t cover everyone, there’s also the category that:
6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now
Have I missed any group off this list?
You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.
Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.
Microsoft has removed KB5029351 update
only from windows update though
KB5029351 is still available from the ms update catalog site
1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.
2. I have installed it in a 11 years old computer, and no problems at all.
3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.
This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.
Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.
Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.
Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.
motherboard maker MSI has recently released a statement regarding the “unsupported processor” blue screen error for their boards using Intel 600/700 series chipsets & to avoid the KB5029351 Win11 update:
https://www.msi.com/news/detail/MSI-On–UNSUPPORTED-PROCESSOR–Error-Message-of-Windows-11-Update-KB5029351-Preview-142215
check out the following recent articles:
Neowin – Microsoft puts little blame on its Windows update after UNSUPPORTED PROCESSOR BSOD bug:

While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.
My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
motherboard maker MSI has recently released new BIOS/firmware updates for their Intel 600 & 700 series motherboards to fix the “UNSUPPORTED_PROCESSOR” problem (Sept. 6):

I try to disable the Diagnostics Tracking Service (Connected Devices Platform User Services) but it wont let me disable it, any help will be greatly appreciated.
Tank you for your help
