Toolkit Item: Introducing Windows Update Manager – Replacement for WUMT

I’ve written about the Windows Update MiniTool, aka WUMT many times. That includes the Win10.Guru post “Toolkit Item: Windows Update Manager (WUMT).” As good as WUMT is, a new program from eastern European programmer David Xanatos is better. It’s called Windows Update Manager, aka WuMgr, and it’s free, Open Source, and readily available, including from the author’s own GitHub pages as well as from trusted source MajorGeeks.


The layout and operation of WuMgr is a deliberate homage to WUMT. It’s almost exactly the same in look, but offers useful and important additional functions.

What Makes WuMgr Better Than WUMT?

Lots of things, according to developer David Xanatos, with whom I conducted a Skype interview in late October 2018. To begin with, WuMgr is Open Source and is being actively and openly maintained. By contrast, WUMT hasn’t been changed much (or at all) since 2016, and is not Open Source. Xanatos designed WuMgr with versions of Windows 10 (e.g. Home) that don’t support the Group Policy Editor, and GPO controls over Windows Update. It’s built in C# (C-Sharp), where WUMT is built in C/C++. This means that WuMgr can handle .COM objects directly, whereas WUMT had to use wrapper code to access them indirectly. And although the two programs look quite simliar, Xanatos says “there’s no reverse engineering involved” in the construction of WuMgr. In my personal experience, WuMgr runs faster than WUMT.

One more thing: you can use WuMgr directly and explicitly to manage the host PC’s relationship with Windows Update itself. Doing that with WUMT requires the WUMT wrapper script (or simliar tools) which Gary Thurman created around WUMT (and is now adapting for WuMgr as well; see Sledgehammer for the most current version). WuMgr offers direct control over Windows Update (WU) through its Options and Auto Update tabs. The Auto Update tab permits users to block a PC’s access to WU Servers. It also lets them disable Automatic Update (and the subsidiary Update Facilitators that MS has introduced in Win10 Builds since 1703). This tab also includes the ability to get update notification only or download only, so that users can explicitly and directly control what gets installed (along with scheduling controls). Users can also use this tab to hide the WU page in Settings, to disable Auto Updates for the Microsoft Store, and to include or exclude device drivers from what gets downloaded from Windows Update. Here’s what that looks like in the program:

The options tab (at top left in preceding screen capture) provides additional update controls. The pick list in the top line lets users designate the source from which updates will come, including Windows Update (the default), Dcat Flighting Prod, Windows Store, Windows Store (Dcat Prod), or Microsoft Update (predecessor to WU). It lets users elect for the program to operate in offline mode (which means it can configure interactions with a download source, and defer those interactions until an online connection becomes available, or the user fires off a manual update), and explicit controls to force the user to authorize download and install of updates. It can include superseded update packages in the listings of available updates (normally disallowed), run in the background at startup (with a variety of controls over when and how the program looks for updates) and be set to always “Run as Administrator.” Here’s what that looks like in WuMgr:

I think WuMgr is a must-have tool for any serious Windows 10 administrator or power user. It restores complete and explicit control over how, when, and which updates will be applied to a target PC, which is something that has vexed and eluded most users since Windows 10 was introduced in October 2014. This is a terrific, highly usable program that should be part of the general admin toolkit for Windows 10, period. [Note: Updated on 10/21/2019 to cover the latest version of WuMgr, v1.0. Thanks to Martin Brinkmann at Ghacks.net, through whose site I discovered this latest version became available on 10/19/2019.]

    Excellent find! Thank you!

    I tried this app but it seems like having bugs. I have windows 10 1709 and upgrade size of 1803 it is showing is 90gb+!!

    Dear Shailesh:
    This is a mis-reporting error from Windows Update itself. I’ve seen it many times in both WUMT and WuMgr. If I remember correctly, it’s caused by adding up many instances of individual files with internal “hard links” that leads to mis- and over-reporting of the download size. It’s benign, though, and does not indicate program pathologies as far as I can tell. In most cases, Windows upgrades seldom exceed 5 GB in size; updates seldom go over 3-4 GB. HTH, and thanks for sharing your observation with us.

    Thank you very much for making us aware of WuMgr.

    Now I find it would be great if somebody throws some light on how to use the “Options” and “Auto Update” settings of WuMgr for us (not-that-savvy) users…
    For example, what boxes should I check:
    1. to havei WuMgr block all Windows update activity by default; and
    2. to manually check for updates, and manually download and install them when I see fit?

    In Windows 7, I knew how to set WU to do exactly that.

    But Microsoft’s recent approach is hitting many of us users very hard.

    I work on a standby basis, a Windows 10 Notebook being my main tool (any time of the day or night).
    And there are times I *really* cannot afford my machine slowing down due to a Windows update download (or being distracted by update notifications).

    Being able to take control of WU is very important for a lot of us!

    Indeed, you can configure WuMgr as you’ve described so that it will only download and install updates when you allow it to do so. Everything blocked otherwise. If you’re asking for my permission or approval: you’ve got it. That’s one of the main things that WuMgr is supposed to support, so you’re making appropriate and proper use of the program by so doing.

    Please note that David Xanatos released a new version of WuMgr.exe, v 1.0, on 10/19/2019. I’ve updated the story and its links to reflect this update, and also added a pointer to Gary Thurman’s replacement for the WUMT wrapper script, now know as Slegehammer.

    Nice article and helpful comments here. I’m glad someone finally “documented” the Options and Auto Update tabs!

    Hi Ed,
    Do you know what “Register Microsoft Update” is for?
    Thanks . . .

    Hi there,
    Wumgr looks like exactly what I need but how do you RUN IT? I have D/L the zip but it contains no application as such. What do I click on to get the thing to open? Can you help please? Something of an emergency here.

    My new windows 10 Dell Laptop has adopted the very annoying habit of waking up machine from sleep (standby) status when Windows is issuing a notice that “update is available” for Windows Defender. Which happens daily. I did some reading online and it seems a LOT of people are having problems with this. I found suggestions about modifying Windows UpdateOrchestrator to stop this “wake from sleep” behavior. Seems pretty complicated. Quite some time ago I using the Group policy Editor according to online instructions to stop automatic windows updates, and only to notify when available. That worked pretty well for 6 months or so, but a recent Win10 update has started this “wake from sleep” behavior which is terrible. One article I read recommended this page and WuMgr. Can I use it to simply disable this one behavior without doing a whole system reconfiguration? Any specific advice would be much appreciated.

    Dear Alison:
    when I unpack the zip, it deposits a file named wugmr.exe in the unzip target directory. That’s what I run (as administrator, unless configured to do so in the program’s own settings). It works just fine for me. when I click on the double-headed circle (to have it check for updates) that works, too. It found a couple of drivers for my Lenovo X380 test machine, in fact, and installed them for me successfully, too.

    Dear Joseph:
    You should be able to click the “Manual” Download/Install button at the lower left of the WUMgr.exe UI. If all other boxes are unchecked, then it should check for updates only when you run this program and instruct it to check and/or download install such updates. Worth a try, anway.

    I have not figured out what “installed Updates” means vs “Update History”. I installed some updates and they are now listed in the “Installed Updates” section and not History. When I get out of WuMgr and back in the Installed Updates do not show up until i do a check for updates. I ran the the Nirsoft Windows Update History https://www.nirsoft.net/utils/windows_updates_history_viewer.html I does not show any of the items in the “Installed Updates” section (that only show on check for update).

    What am I missing?

    There is no .exe file included in the zip. Does this need to be compiled now ?

    To answer my own question the GitHub link does not include a .exe file (I assume this is the original source code and needs to be compiled to work?) But the link from MajorGeeks has the executable.

  15. April 19, 2020 at 20:46

    There doesn’t appear to be a way to block a SPECIFIC update.

  16. April 19, 2020 at 20:50

    The github download does indeed include an .exe file. Go here, scroll down, and pick WuMgr_vx.x.zip


  17. April 22, 2020 at 18:18

    Dear Louis: Johny is right. If you download and unpack the ZIP file, you’ll find an .exe file therein. Easy-peasey!
