Unified Write Filter not working

Question

_{Wednesday, August 2, 2017 8:08 AM}

Hi,

I am working on unified write filter. On windows 10 Enterprise, i am configuring UWF by following official link ('Turn UWF on or off' section). 

https://docs.microsoft.com/en-us/windows-hardware/customize/enterprise/unified-write-filter

When i select "unified write filter' in windows feature, it configure it and reboot the system. After that i can see uwfmgr.exe in System32 folder (which was never before).

Actual problem is that, when i run it manually it opens and closes in a sec. And when running it with command prompt, the commands runs and new input line starts with no effect at all. Besides, every command shows the same behavior e.g 'uwfmgr.exe c:' 'uwfmgr.exe enable' or simple 'uwfmgr' even shows no error or output.

Can anyone solve this problem?

NOTE: i have tried this on virtual machine as well as on laptop using windows 10 enterprise, windows 10 Pro but all resulted the same.

Thanks in advance

After testing all the presented solutions. I finally downloaded the latest ISO and all working fine. Its weird but it solved my problem.

Reading the uwfmgr.exe looks like a command-line, are you running this from a command-line?

Try to turn UWF on by using DISM, you will be able to see the feature is enabled successfully.

DISM.exe /Online /enable-Feature /FeatureName:client-UnifiedWriteFilter

After that, there will be a Uwfmgr file under the %WINDIR%\System32\ folder.

Running UWFMGR in a command window with admin privileges.

Yes i am running UWFMGR with admin privileges but nothing shows up. no success message, no error message, nothing. And there is no Event Logs in the event viewer location.

I configured it with DISM command which you mentioned and it in response it displays that feature enabled successfully and in System32 folder i find the uwfmgr.exe as well. But when i run command on CMD it shows nothing.
Don't know why this all happening. I am using windows 10 Enterprise and also did it for Education version and not embedded version.

Just tried this with the DISM command, got a error 50 by default and it suggested add /all so did that go prompted for reboot. So try;

DISM.exe /Online /enable-Feature /FeatureName:client-UnifiedWriteFilter /all

See if that helps. UWFMGR for me brings back the help information when I enter just that.

Thanks for bearing with me.

In both cases, weather i run with or without '/all' the behavior is the same. it loads the management tool and then turn ON the feature and shows the progress.

When it boots up, UWFMGR command neither shows help information nor anything. and if i go in System32 and run UWFMGR.exe manually, it opens and closes like a blink of an eye.

Tried this on a couple of machine now all when running uwfmgr from a command prompt that displays the help.

So version of Windows 10 ? 1703? LTSB or what version?

So are these domain pc's you are trying this on? If so can you build a standalone one as a test?
