Identifier:

        $(($KeyProtectorsInputFromScriptBlock | Where-Object -FilterScript { $_.keyprotectortype -eq 'RecoveryPassword' }).KeyProtectorId.Trim('{', '}'))

If the above identifier matches the one displayed by your PC, then use the following key to unlock your drive.

Recovery Key:

        $(($KeyProtectorsInputFromScriptBlock | Where-Object -FilterScript { $_.keyprotectortype -eq 'RecoveryPassword' }).RecoveryPassword)

If the above identifier doesn't match the one displayed by your PC, then this isn't the right key to unlock your drive.
Try another recovery key, or refer to https://learn.microsoft.com/en-us/windows/security/operating-system-security/data-protection/bitlocker/recovery-overview for additional assistance.

IMPORTANT: Make sure to keep it in a safe place, e.g., in OneDrive's Personal Vault which requires additional authentication to access.

.SYNOPSIS
    Applies the hardening measures described in the GitHub readme.
.LINK
    https://github.com/HotCakeX/Harden-Windows-Security
.DESCRIPTION
    Applies the hardening measures on a Windows client OS. You can run this cmdlet in interactive or headless/unattended mode.
    In interactive mode, you will be prompted for confirmation before applying each category and sub-category.
    In headless/unattended mode, you can specify which categories to apply without the need for user interaction.
    When running in headless/unattended mode, you can control the sub-categories of each category by using the following switch parameters:

    SecBaselines_NoOverrides -> Applies the Microsoft Security Baselines without the optional overrides
    MSFTDefender_SAC -> Enables Smart App Control
    MSFTDefender_NoDiagData -> Will not enable optional diagnostics data required for Smart App Control (Does not have any effect if Smart App Control is already turned on)
    MSFTDefender_NoScheduledTask -> Will not create scheduled task for fast MSFT driver block rules update
    MSFTDefender_BetaChannels -> Set Defender Engine and Intelligence update channels to beta
    LockScreen_CtrlAltDel -> Require CTRL + ALT + Delete at lock screen
    LockScreen_NoLastSignedIn -> Will not display the last signed in user at the lock screen
    UAC_NoFastSwitching -> Hide entry points for fast user switching
    UAC_OnlyElevateSigned -> Only elevate signed and validated executables
    CountryIPBlocking_OFAC -> Include the IP ranges of OFAC Sanctioned Countries in the firewall block rules

    Each of the switch parameters above will be dynamically generated based on the categories you choose.
    For example, if you choose to run the Microsoft Security Baselines category, the SecBaselines_NoOverrides switch parameter will be generated and you can use it to apply the Microsoft Security Baselines without the optional overrides.
.COMPONENT
    PowerShell
.FUNCTIONALITY
    Applies the hardening measures described in the GitHub readme.
.PARAMETER Categories
    The hardening categories to implement. Use this to selectively apply certain categories.
    Use this parameter when executing the Protect-WindowsSecurity in silent/headless mode to automatically apply any categories you desire without user intervention.
    If not specified, there will be requests for confirmation before running each category.
.PARAMETER Verbose
    Activates elaborate messages by displaying extensive information about the actions of the Protect-WindowsSecurity cmdlet.
.PARAMETER Log
    Activates comprehensive logging by recording all the information shown on the screen and some additional data to a text file. It is strongly advised to use the -Verbose parameter when you want to enable logging.
.PARAMETER LogPath
    The path to save the log file to. If not specified, the log file will be saved in the current working directory.
.PARAMETER Offline
    Indicates that the module is being run in offline mode. Will not download any files from the internet.
    Using this parameter will make the following 3 parameters mandatory: PathToLGPO, PathToMSFTSecurityBaselines and PathToMSFT365AppsSecurityBaselines.
.PARAMETER PathToLGPO
    The path to the 'LGPO.zip'. Make sure it's in the zip format just like it's downloaded from the Microsoft servers.
    File name can be anything.
    The parameter has argument completer so you can press tab and use the file picker GUI to select the zip file.
.PARAMETER PathToMSFTSecurityBaselines
    The path to the 'Windows 11 v23H2 Security Baseline.zip'. Make sure it's in the zip format just like it's downloaded from the Microsoft servers.
    File name can be anything.
    The parameter has argument completer so you can press tab and use the file picker GUI to select the zip file.
.PARAMETER PathToMSFT365AppsSecurityBaselines
    The path to the 'Microsoft 365 Apps for Enterprise 2306.zip'. Make sure it's in the zip format just like it's downloaded from the Microsoft servers.
    File name can be anything.
    The parameter has argument completer so you can press tab and use the file picker GUI to select the zip file.
.NOTES
    It is highly recommended to always include the Microsoft Security Baselines category and place it first as it forms the foundation of all subsequent categories.
.EXAMPLE
    Protect-WindowsSecurity -Categories 'MicrosoftSecurityBaselines', 'MicrosoftDefender', 'AttackSurfaceReductionRules'

    This example will apply the Microsoft Security Baselines, Microsoft Defender and Attack Surface Reduction Rules categories without the need for user interaction.
.EXAMPLE
    Protect-WindowsSecurity -Categories MicrosoftDefender -MSFTDefender_SAC -Verbose

    This example will apply the Microsoft Defender category with the Smart App Control sub-category, without the need for user interaction, and will show verbose messages.
.EXAMPLE
    Protect-WindowsSecurity

    This example will run the cmdlet in interactive mode and will prompt for confirmation before running each category and sub-category.
.EXAMPLE
    Protect-WindowsSecurity -Verbose -Offline -PathToLGPO 'C:\Users\Admin\Desktop\LGPO.zip' -PathToMSFTSecurityBaselines 'C:\Users\Admin\Desktop\Baselines.zip' -PathToMSFT365AppsSecurityBaselines 'C:\Users\Admin\Desktop\M365Baselines.zip' -Log -Categories MicrosoftSecurityBaselines,MicrosoftDefender -MSFTDefender_SAC

    This example instructs the cmdlet to run in offline mode and will not download any files from the internet.
    It also runs it in headless/silent mode by specifying which categories to automatically run. -MSFTDefender_SAC switch is used so the Smart App Control sub-category is also applied in the headless/silent mode.
    -Log switch is mentioned which will save the output of the cmdlet to a text file in the current working directory.
