When Windows 10 doesn’t recognise your DVD device any more

Posted by jpluimers on 2019/02/22

Yes, some people still use DVD devices. My mentally retarded brother does every now and then, so it was a big problem that one day he could not put play a photo DVD any more.

This happened:

The selected device was gone. Reboots (including cold ones) didn’t help.

What helped was selecting the “Dual Channel PCI IDE Controller”, remove it, then reboot so Windows would try to re-install the drivers. After that the DVD drive appeared again.

Later I found these two links with similar solutions:

List of Shell GUIDs for various Windows versions for use in shortcuts and batch files

Posted by jpluimers on 2019/01/09

In my search for starting the Windows Credential Manager from the console, I found [WayBackCredential Manager Shortcut – Create – Windows 7 Help Forums explaining:

%windir%\explorer.exe shell:::{1206F5F1-0569-412C-8FEC-3204630DFB70}

This reminded me of From batch file or shortcut: start Windows Update (via: Windows 7 Help Forums) and batch-file trick: Starting Windows Explorer and selecting a file (“explorer” commandline parameters “/n” “/e” “/select” “/root” “/start” site:microsoft.com).

The odd thing is that some of the GUID shortcuts works fine using the shell::: syntax, but fail with the /e:: syntax, for instance Windows Update until Windows 8.1:

%windir%\explorer.exe shell:::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}
%windir%\explorer.exe /e,::{36eef7db-88ad-4e81-ad49-0e313f0c35f8}

One day I’ll create a table of permutations for various Windows versions and execute options.

For now these links need to suffice:

Adding Windows machines to Samba domains and security

Posted by jpluimers on 2018/12/07

If adding a Windows machine to a Samba domain fails and the below “solves” your issue, then you need to tighten the security on the Samba side:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters]
; Enable NT-Domain compatibility mode
; Default:
; [value not present]
; "DomainCompatibilityMode"=-
"DomainCompatibilityMode"=dword:00000001

; Disable required DNS name resolution
; Default:
; [value not present]
; "DNSNameResolutionRequired"=-
"DNSNameResolutionRequired"=dword:00000000


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Netlogon\Parameters]
; Disable requirement of signed communication
; My Samba (3.0.33) works with signed communication enabled, so no need to disable it.
; Default:
; "RequireSignOrSeal"=dword:00000001
; Disable the usage of strong keys
; Default:
; "RequireStrongKey"=dword:00000001
"RequireStrongKey"=dword:00000000

UTF-8 support for single byte character sets is beta in Windows and likely breaks a lot of applications not expecting this (via Unicode in Microsoft Windows: UTF-8 – Wikipedia)

Posted by jpluimers on 2018/12/04

Uh-oh: [WayBack] Unicode in Microsoft Windows: UTF-8 – Wikipedia:

Microsoft Windows has a code page designated for UTF-8code page 65001. Prior to Windows 10 insider build 17035 (November 2017),[7] it was impossible to set the locale code page to 65001, leaving this code page only available for:

  • Explicit conversion functions such as MultiByteToWideChar
  • The Win32 console command chcp 65001 to translate stdin/out between UTF-8 and UTF-16.

This means that “narrow” functions, in particular fopen, cannot be called with UTF-8 strings, and in fact there is no way to open all possible files using fopen no matter what the locale is set to and/or what bytes are put in the string, as none of the available locales can produce all possible UTF-16 characters.

On all modern non-Windows platforms, the string passed to fopen is effectively UTF-8. This produces an incompatibility between other platforms and Windows. The normal work-around is to add Windows-specific code to convert UTF-8 to UTF-16 using MultiByteToWideChar and call the “wide” function.[8] Conversion is also needed even for Windows-specific api such as SetWindowText since many applications inherently have to use UTF-8 due to its use in file formats, internet protocols, and its ability to interoperate with raw arrays of bytes.

There were proposals to add new API to portable libraries such as Boost to do the necessary conversion, by adding new functions for opening and renaming files. These functions would pass filenames through unchanged on Unix, but translate them to UTF-16 on Windows.[9] This would allow code to be “portable”, but required just as many code changes as calling the wide functions.

With insider build 17035 and the April 2018 update (nominal build 17134) for Windows 10, a “Beta: Use Unicode UTF-8 for worldwide language support” checkbox appeared for setting the locale code page to UTF-8.[a] This allows for calling “narrow” functions, including fopen and SetWindowTextA, with UTF-8 strings. Microsoft claims this option might break some functions (a possible example is _mbsrev[10]) as they were written to assume multibyte encodings used no more than 2 bytes per character, thus until now code pages with more bytes such as GB 18030 (cp54936) and UTF-8 could not be set as the locale.[11]
