:: INSTRUCTIONS
:: Find the "EDIT" lines and change them according to your requirements and organization. Some lines
:: are not appropriate for large companies using Active Directory infrastructure, others are fine for small organizations, 
:: others are fine for individual users. At the start of tricky lines, I've added guidelines. 
:: It is a good idea to create a System Restore point before you run the script - as there are more than 920 lines in it,
:: finding out which line broke your machine is going to be trickly. You can also run the script in sequences manually the 
:: first few times, reboot, test your software and connectivity, proceed with the next sequence - this helps with troubleshooting.
:: HOW TO RUN THE SCRIPT
:: The command below creates the restore point, you can do it manually, too. 
powershell.exe enable-computerrestore -drive c:\
powershell.exe vssadmin resize shadowstorage /on=c: /for=c: /maxsize=500MB
:: checkpoint-computer -description "beforehardening"
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore" /v SystemRestorePointCreationFrequency /t REG_DWORD /d 20 /f
powershell.exe -ExecutionPolicy Bypass -Command "Checkpoint-Computer -Description 'BeforeSecurityHardening' -RestorePointType 'MODIFY_SETTINGS'"
:: 1. In Settings, search for Restore, then choose Create a restore point, then in System Protection, make sure it is On and has at least 6% of the drive.  
:: Create a Restore point, name it "Prior Security Hardening" 
:: 2. Go to https://raw.githubusercontent.com/atlantsecurity/windows-hardening-scripts/main/Windows-10-Hardening-script.cmd and download the cmd script to Downloads. 
:: It will download it as .txt - go to View in folder options, enable file extensions, change the filename to .cmd.  
:: 3. Open Powershell as Administrator, then type cd ~, then type cd .\Downloads\, type ls, type cmd 
:: 4. Type "Windows-10-Hardening-script.cmd"
:: 5. If you experience problems and need to roll back, roll back using the system restore point you created.

:: Prevent Edge from running in background
:: On the new Chromium version of Microsoft Edge, extensions and other services can keep the browser running in the background even after it's closed. 
:: Although this may not be an issue for most desktop PCs, it could be a problem for laptops and low-end devices as these background processes can 
:: increase battery consumption and memory usage. The background process displays an icon in the system tray and can always be closed from there. 
:: If you run enable this policy the background mode will be disabled.
