reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "$env:ProgramFiles\Notepad++\notepad++.exe -notepadStyleCmdline -z" /f

Or?

1. check if we have 64 or 32 bit notepad++

if (Test-Path "C:\Program Files\Notepad++\notepad++.exe") { echo "64bit" } `
elseif (Test-Path "C:\Program Files(x86)\Notepad++\notepad++.exe") {echo "32bit"} `
else {echo "Not installed!"}

1. Make notepad++ the default

reg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe"

1. In cmd.exe:

REM If 64-bit Notepad++
reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "\"%ProgramFiles%\Notepad++\notepad++.exe\" -notepadStyleCmdline -z" /f

REM If 32-bit Notepad++
reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "\"%ProgramFiles(x86)%\Notepad++\notepad++.exe\" -notepadStyleCmdline -z" /f

1. In Powershell:
2. 64bit

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "$env:ProgramFiles\Notepad++\notepad++.exe -notepadStyleCmdline -z" /f

1. 32bit

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "$env:ProgramFiles(x86)%\Notepad++\notepad++.exe -notepadStyleCmdline -z" /f

The old Solitaire from Windows 95. 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/)
