Windows <= 10: batch file to open Windows Update panel

Posted by jpluimers on 2019/02/15

Up until Widows 8.1, you could use wuapp to start the Windows Update panel.

For a while, Windows 10 needed a cumbersome language specific workaround described at Windows 10 – language neutral batch file to start Windows.

That stopped working after a few builds, but I forgot to make a note in which build exactly. Already in Windows 10 build 10122, the icon in wucltux.dll, so this might have been shortly after the initial “RTM” (retroactively named 1507).

So for a while, I had this batch file:

Since then I had to maintain too many locales running Windows 10. So here is the batch file:

for /f "delims=" %%A in ('PowerShell -Command "(Get-Culture).Name"') do explorer "%LocalAppData%\Packages\windows.immersivecontrolpanel_cw5n1h2txyewy\LocalState\Indexed\Settings\%%A\AAA_SystemSettings_MusUpdate_UpdateActionButton.settingcontent-ms"

It uses these tricks:

  1. Set output of a command as a variable (in this case a for loop variable)
  2. Execute PowerShell script in a .bat file
  3. PowerShell Get-Culture (which gets a .NET CultureInfo instance)
  4. CultureInfo.Name property (which has the nl-NL, en-US, etc codes in it)

But now I have extended it to support old and new Windows versions:

if exist %windir%\System32\wuapp.exe (
  %windir%\System32\rundll32.exe url.dll,FileProtocolHandler wuapp.exe
) else (
  %windir%\explorer ms-settings:windowsupdate

To celebrate his 85th birthday, some links to interviews with Niklaus Wirth interviews

Posted by jpluimers on 2019/02/15

Today, Niklaus Wirth, “father” of The Pascal Programming Language turned 85.

Happy birthday!

Almost 50 years ago, Niklaus Wirth submitted his famous paper “The Programming Language Pascal” which was published early 1971

Luckily it is archived on both the WayBack machine and as the only PDF copy I could find on-line isn’t always on-line:

Originally it was published by Niklaus Wirth  in Acta Informatica, Vol. 1, Fasc. 1, 1971 pp. 35-63

He has been very active, just browse through the [WayBack] List of computer science publications by Niklaus Wirth

To celebrate his birthday, here are some interviews with him:

If you like the ones above as much as I do, then search for more: there are plenty!

VNC, Windows and UAC prompts

Posted by jpluimers on 2019/02/15

Since I needed to maintain a Windows PC behind a VPN connection via the console (so not via RDP sessions) including installation of software, I needed a (preferably free or open source) solution supporting elevation through UAC (User Account Control).

For a good description of differences between RDP and VNC, see [WayBack] remote desktop – TightVNC while an RDP session is running – Super User by [WayBackUser Canadian Luke.

Of the many non functional search results, the one suggesting running UltraVNC as a service is the one that really worked: [WayBack] If you install UltraVNC as a service, you can see the UAC notifications and press the buttons… VNC on windows 7 with administrator rights – Super User.

  1. I only needed the “Ultra VNC Server Silent” installation (see screenshot below).
  2. Be sure to set a good password though in UltraVNC settings, then restart the service in the Service page on the same tab.

Now I can use Screen Sharing on my Mac to access the machine via a VPN over the VNC protocol. Combined with a Wake On LAN feature in the remote network, this works splendid.

One thing I’ve to figured out has to do with keyboard mappings: the Mac local Command key maps to the remote Alt key (using Microsoft Remote Desktop it would map to the remote Windows key), but I’ve not figure out what maps to the remote Windows key yet.

Note this fails for [WayBackUltraVNC • View topic – UltraVNC SC – UAC Window Doesnt shown. The reason is that the Single Click version runs as an unelevated user process. So off the list [WayBackSingle Click – UltraVNC VNC OFFICIAL SITE, Remote Access, Support Software, Remote Desktop Control Free Opensource


PS: [WayBackmacos – Wake Other Computers from Mac OSX – Ask Different

PS2: I’m not sure about the difference between “Silent” and regular – see [WayBackUltraVNC • View topic – UltraVNC Server “Silent” – Install option
