# See the help for Set-StrictMode for the full details on what this enables. Set-StrictMode -Version 2.0 Function Get-VitalInformation { <# .SYNOPSIS Retrieves system information and inventory .DESCRIPTION The following tasks are available: - ComponentStoreAnalysis Performs a component store analysis to determine current statistics and reclaimable space. This task requires administrator privileges. - ComputerInfo Retrieves baseline system hardware and operating system information. This task requires Windows PowerShell 5.1 or newer. - CrashDumps Checks for any kernel or service account crash dumps. This task requires administrator privileges. - DevicesNotPresent Retrieves any PnP devices which are not present. Devices which are not present are those with an "Unknown" state. This task requires Windows 10, Windows Server 2016, or newer. - DevicesWithBadStatus Retrieves any PnP devices with a bad status. A bad status corresponds to any device in an "Error" or "Degraded" state. This task requires Windows 10, Windows Server 2016, or newer. - EnvironmentVariables Retrieves environment variables for the system and current user. - HypervisorInfo Attempts to detect if the system is running under a hypervisor. Currently we only detect Microsoft Hyper-V and VMware hypervisors. - InstalledFeatures Retrieves information on installed Windows features. This task requires a Window Server operating system. - InstalledPrograms Retrieves information on installed programs. Only programs installed system-wide are retrieved. - StorageVolumes Retrieves information on fixed storage volumes. This task requires Windows 8, Windows Server 2012, or newer. - SysinternalsSuite Retrieves the version of the installed Sysinternals Suite if any. The version is retrieved from the Version.txt file created by Invoke-VitalMaintenance. The location where we check if the utilities are installed depends on the OS architecture: * 32-bit: The "Sysinternals" folder in the "Program Files" directory * 64-bit: The "Sysinternals" folder in the "Program Files (x86)" directory - WindowsUpdates Scans for any available Windows updates. Updates from Microsoft Update are also included if opted-in via the Windows Update configuration. This task requires administrator privileges and the PSWindowsUpdate module. The default is to run all tasks. .PARAMETER ExcludeTasks Array of tasks to exclude. The default is an empty array (i.e. run all tasks). .PARAMETER IncludeTasks Array of tasks to include. At least one task must be specified. .EXAMPLE Get-VitalInformation -IncludeTasks StorageVolumes, InstalledPrograms Only retrieves information on storage volumes and installed programs. .NOTES Selected inventory information is retrieved in the following order: - ComputerInfo - HypervisorInfo - DevicesWithBadStatus - DevicesNotPresent - StorageVolumes - CrashDumps - ComponentStoreAnalysis -
