Set-WinSystemLocale en-US
Set-WinUserLanguageList en-US

Or https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/dism-languages-and-international-servicing-command-line-options ?

But the language packs need to be downloaded. Easier in Control Panel.

Try

Set-WinUserLanguageList -Force -LanguageList fr-CH,de-CH,en-US

Disable "Fast boot"

@echo off

echo "Hiberboot (Fast boot) settings"
echo "Current:"

reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /v HiberbootEnabled

echo "Disabling..."
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /v HiberbootEnabled /t REG_DWORD /d 0 /f

echo "New:"
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /v HiberbootEnabled

PAUSE

I think the above registry hack is the same as running

powercfg /hibernate off

and then deleting the C:\hiberfil.sys file

Change NetWorkConnection Category to Private. (Requires -RunasAdministrator)

Get-NetConnectionProfile |
  Where{ $_.NetWorkCategory -ne 'Private'} |
  ForEach {
    $_
    $_ | Set-NetConnectionProfile -NetWorkCategory Private -Confirm
  }

netsh wlan show profiles
netsh wlan delete profile name="WiFi network name"

or delete all:

netsh wlan delete profile name=*

From https://4sysops.com/archives/disable-ipv6-in-windows/

Get-NetAdapterBinding -ComponentID "ms_tcpip6" | where Enabled -eq $true | Disable-NetAdapterBinding -ComponentID "ms_tcpip6"

or (probably needs restart?):

reg add "HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents /t REG_DWORD /d 255 /f

or the same in PowerShell:

New-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\ -Name DisabledComponents -Type DWord -Value 255

The Value 32 may be better than 255.

Or a .reg file (here with value 32 (hex 20)):

NoIPv6.reg

Or maybe netsh commands as suggested in https://systemadminspro.com/how-to-disable-ipv6-on-windows/ (needs a restart)

netsh interface ipv6 6to4 set state disabled
netsh interface ipv6 isatap set state disabled

The old Solitaire from Windows 95.

This assumes there is already a C:\bin directory, and it's in the Path:

cd C:\bin
curl.exe -O -R http://alma.ch/install/win7/bin/sol.exe
curl.exe -O -R http://alma.ch/install/win7/bin/cards.dll

To install it in Ubuntu Linux for running it with wine :

# If not done already, install wine
sudo apt install wine winetricks
# and run wine at least once to make it create it's directories in your $HOME
wine
 
# Install Solitaire
wget http://alma.ch/install/win7/bin/{sol.exe,cards.dll}
mv -t ~/.wine/drive_c/windows/ sol.exe cards.dll
 
# run Solitaire with
wine sol

To check which paths are ignored by Windows Defender:

Get-MpPreference

or

reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Exclusions\Paths" /s
reg query "HKLM\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths" /s

To protect paths from Windows Defender (so that it doesn't delete nc.exe for example):

Add-MpPreference -ExclusionPath "C:\bin"

or

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Exclusions\Paths" /d 0 /t REG_SZ /v "C:\bin"
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Exclusions\Paths" /d 0 /t REG_SZ /v "\\server\install\bin"

With the 2nd option using Policies, they must also be activated by rebooting or by running gpudate /force (see also https://cloudbrothers.info/create-persistent-defender-av-exclusions-circumvent-defender-endpoint-detection/)
