.NET

.NET Version herausfinden

Variante 1

In Registry nachschauen unter HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\NET Framework Setup\NDP\v4\Full, im Feld release, die 6-stellige Nummer in Klammern. (siehe auch https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed)
Release-Nummer unter https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed#version_table nachschauen.

Variante 2

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse | Get-ItemProperty -Name Version,Release -ErrorAction SilentlyContinue | Where-Object { $_.PSChildName -match '^(?!S)\p{L}'} | Select-Object PSChildName, Version, Release

Windows Services/Dienste

cdpusersvc deaktivieren

In Registry nach key cdpusersvc suchen. Überall bei "start" auf 4 setzen.
admin-cmd öffnen, dann pwsh.
sc config cdpusersvc type=own
nssm remove cdpusersvc

CMD

run CMD as different user

runas /user:"infra.vs.ch\fedcom" cmd

if you want to use system user:

Auf Server PsExec installieren https://docs.microsoft.com/en-us/sysinternals/downloads/psexec
CMD als Admin ausführen
PsExec64.exe -s cmd
Test mit Befehl: whoami. Dann sollte nt authority\system erscheinen.

Access fileshare in CMD

If you’ve ever tried to access a network file share in a command prompt by simply using the cd command, you’ll know that it just complains that “CMD does not support UNC paths as current directories”. Well, there is a way to do it (two in fact):

net use

net use z: \\machine\share

It can be combined with the /user switch to provide additional user details:

net use z: \\machine\share /user:domain\username

delete:

net use p: /delete

pushd

pushd \\machine\share

The bonus of using the pushd command over the net use command is that it will automatically change the current directory to the mapped drive (which will be the first unused drive letter available in reverse alphabetical order). Also, when finished with the network share, you can use the popd command to remove the mapped drive.

run multiple batch files in one file

cmd.exe /C, danach die bat-Datei in Anführungszeichen, und Parameter je nachdem ob sie gebraucht werden. Weil ein Misch ist, ein @ davor setzen.

Bsp. Inhalt einer Master-.bat Datei, mit mehreren bat Aufrufen (und einer env-variable)

cmd.exe /C @"fedora-purge.bat" abc.def.ch:8443 fedoraAdmin %FEDORAPW% CH-000999-4:328110 https "delete because more recent version CH-000917-4:331101"
cmd.exe /C @"fedora-purge.bat" abc.def.ch:8443 fedoraAdmin %FEDORAPW% CH-000999-4:328111 https "delete because more recent version CH-000917-4:331101"
