It is fair to say that Samsung products haven't had the best time so far on some of the latest Windows 11 versions. The South Korean giant came under fire recently as it came to notice that its Connect app was messing with Windows 11 updates leading to the system drive (C:) becoming inaccessible. Microsoft later published a detailed guidance article that walks through the fixes.
Interestingly, in the first article I linked above, a related comment caught my attention. Posted by a forum member M. Murcek, who has been around on Neowin for a while, pointed out another crucial Samsung software, which has been broken on Windows 11 for the last several months.
They wrote: "Not what's being discussed in the article, but Samsung Magician has been broken in Canary builds for a while now," to which another one of our readers wotsit responded "I don’t do any Insider stuff but Magician never opens for me," confirming that this Samsung Magician bug they are talking about has been encountered by others too, and outside of Insider channel alpha/beta Windows testing as well.
After coming across these comments, I did some digging around to see if others outside of Neowin are also having to experience such problems, and, as expected, there were many threads with lots of views and upvotes from online users which suggested that yes, this is a fairly widespread problem that has so far not been reported by mainstream outlets.
The first such thread seems to have popped up back in December 2025 with Samsung Magician version 9.0.0 as it simply would not start on Windows 11. This failure to launch the Magician app seemingly coincides with the release of the native NVMe driver on Servers, so we wonder if anything happened there.
Here is a gist of all the issues users are reporting about the Magician app on Windows:
- Magician app not working/launching/starting
- Display scaling bug such that fonts/texts in the app are unreadable, illegible
- Speed and performance reduction
- SSDs not being recognized/seen
- Drive health status and monitoring reports missing
Interestingly, the Samsung Magician app version 9.0.0, which is causing the issues on Windows 11 25H2, 24H2, and 26H1, is supposed to be a crucial update for the software as it patched a high-severity privilege escalation flaw (CVE-2025-57836) that allowed attackers to hijack DLLs via its compromised app installer on Windows.
So, it seems users may have no choice but to update to this version of the app since it is a critical one. On the slightly brighter side, there is a new Magician update v9.0.1.950 available which was released earlier this week. The release notes simply says: "Improved the UI/UX to enhance user convenience.
Users can easily use various features with a more intuitive and streamlined screen."
Head over to Samsung's website here to download the app and let us know in the comments below if the new update has resolved your issues. Another positive news is that Microsoft is also working on the native NVMe feature in the background, so perhaps such problems may be addressed from Microsoft's end as well.

To be fair the SSD will work absolutely fine without Samsung magician.
But but but without the Samsung software, you won't have a good "user experience" LOL.
One of the first things I do on a new "store bought" PC is to REMOVE all of that goofy bloatware. 99% of it isn't useful for anything except probably sending data back to the manufacturer!
There is another option uninstall it or install the update
Samsung clowns can't do desktop software right. Their latest OneUI on phones is also a disaster, for initial few years OneUI used to be good
According to whom, exactly? Because both me and my mother have their latest OneUI and everything's perfect, and I haven't read about any widespread issues with it, either. Sure, some users have issues, like with every device on Earth, but it isn't a disaster...
Second fork up from Samsung, after the crashes with the windows update from a couple of weeks ago. Magician software is broken for a while now.
I just opened it up on Windows 11, and I am on version 8.3.2 and it works just fine. It says there is a new version 9.0.1 and it will update it.
The constant "the world is falling Windows 11" issues from Neowin is getting tiring. This software is not even needed. I have another PC with two 990's and it does not even have the software.
From the article: "Interestingly, the Samsung Magician app version 9.0.0, which is causing the issues on Windows 11 25H2, 24H2, and 26H1, is supposed to be a crucial update for the software as it patched a high-severity privilege escalation flaw (CVE-2025-57836) that allowed attackers to hijack DLLs via its compromised app installer on Windows."
also we don't even blame Windows here.
Samsung Magician 9.0.1 dropped a couple days ago and seems to be working on Insider build 29558. All I've done is look at the dashboard but at least my 970 Pro is showing up now.
working fine on one PC but was failing to load on another. Will check if latest update solved the issue.
I have Magician working reliably on my Win11 25H2 (26200.8117) without any issues. It's been working without any problems from Win10 to all updates to now Win11 25H2. It's on a Samsung 980 SSD. Magician did update a couple of days ago.
