For the best results in iterative usage of this script, the default value should remain constant and be set according to the prevailing conditions (at line 18). The default save location for the horizontal (landscape) wallpapers is " $($env:USERPROFILE)\Pictures\Wallpapers", which will be used, if no value for the -Output parameter is defined in the command launching Get-Windows10LockScreenWallpapers. Specifies the primary folder, where the acquired new images are to be saved, and defines the default location to be used with the -Log parameter ( spotlight_log.csv), and also sets the parent directory for the -Subfolder parameter. With aliases -Path, -Destination and -OutputFolder. PowerShell Advanced Functions: Can we build them better?įor instance Get-Windows10LockScreenWallpapers.ps1. Use PowerShell to Remove Metadata and Resize ImagesĬall Windows Runtime Classes from PowerShell This script is forked from robledosm's script Save lockscreen as wallpaper.ĭisk Space (or one of the versions)Ĭreating a Menu (or one of the versions) Please note that if any of the individual parameter values include space characters, the individual value should be enclosed in quotation marks (single or double), so that PowerShell can interpret the command correctly. The other available parameters ( -Force, -Open and -Audio) are discussed in further detail below. The -Log parameter will start a log creation procedure (in case new files were acquired), in which the extracted image properties are written to a new CSV file ( spotlight_log.csv) or appended to an existing log file. To exclude the portrait pictures from the results altogether, the parameter -ExcludePortrait may be added to the command launching Get-Windows10LockScreenWallpapers. The images are loaded as ImageFile COM objects with Microsoft Windows Image Acquisition (WIA, which relies on the Windows Image Acquisition (WIA) service ' stisvc'), and over 300 image properties (usually, though, most of them are empty or non-existent.) are read from the pictures before the new images are copied to their final destination. The primary save location ("destination") may be set with the -Output parameter, and the name of the subfolder may be changed with the -Subfolder parameter – the former accepts a full path as a value, and the latter just a plain directory name. By default Get-Windows10LockScreenWallpapers writes the landscape files to " $($env:USERPROFILE)\Pictures\Wallpapers"(, which is the default -Output directory), and the portrait pictures are placed in a subfolder called " Vertical" inside the folder specified with the -Output parameter. Get-Windows10LockScreenWallpapers uses the inbuilt Get-FileHash cmdlet to calculate SHA256 hash values of the files for determining, whether a wallpaper already exists in the -Output folder or a portrait picture in the -Subfolder directory. By adding the -IncludeHive parameter to the command launching Get-Windows10LockScreenWallpapers the third method of wallpaper searching will be enabled, so that Get-Windows10LockScreenWallpapers will also look to the current lock screen hive, even if the first method (registry) or the second method (estimation) was selected as the primary method for searching the available local lock screen wallpapers. The methods are tested in an ascending order and selected as the primary (only) method, if deemed to be valid. Figuring out the current lock screen hive (which usually is in the $env:windir\Web\Screen directory).Estimating the * value (and the source path) in " $($env:LOCALAPPDATA)\Packages\*\LocalState\Assets" path, which on most Windows 10 machines would most likely point to the " \_cw5n1h2txyewy\LocalState\Assets" directory.Reading a registry key under HKEY_CURRENT_USER: " \SOFTWARE\Microsoft\Windows\CurrentVersion\Lock Screen\Creative\LandscapeAssetPath".Get-Windows10LockScreenWallpapers uses by default one of the three methods below to determine the source path, where the Windows Spotlight lock screen wallpapers are stored locally: Get-Windows10LockScreenWallpapers.ps1 OS:
