| .SYNOPSIS | |
| Add and remove Java Control Panel applet entries in the Windows Control Panel. | |
| .DESCRIPTION | |
| The JavaCPL function collects control panel applet information from the registry. It uses this information to analyze currently visible entries and their status. Based on this information entries can be removed, added or modified. | |
| .PARAMETER Add | |
| Add available Java Control Panel applets to the Windows Control Panel. Existing Java Control Panel applets will not be affected. | |
| .PARAMETER Remove | |
| Remove Java Control Panel applets that are not installed from the Windows Control Panel. Available Java Control Panel applets will remain. | |
| .PARAMETER All | |
| Used with the Remove parameter; Remove all Java Control Panel applets, available and unavailable, from the Windows Control Panel. | |
| .PARAMETER Reset | |
| Remove all Java Control Panel applets from, then add all available Java Control Panel applets to, the Windows Control Panel. | |
| .EXAMPLE | |
| javacpl.ps1 -Verbose | |
| View Java and Windows Control Panel information verbose logging. | |
| .EXAMPLE | |
| javacpl.ps1 -Remove -Verbose | |
| Removes Java Control Panel applets from the Windows Control Panel that are not installed with verbose logging. | |
| .EXAMPLE | |
| javacpl.ps1 -Remove -All -Verbose | |
| Removes all known Java Control Panel applets from the Windows Control Panel with verbose logging. | |
| .EXAMPLE | |
| javacpl.ps1 -Add -Verbose | |
| Adds Java Control Panel applets to the Windows Control Panel that are installed, but not available, with verbose logging. | |
| .EXAMPLE | |
| javacpl.ps1 -Reset -Verbose | |
| Performs a '-Remove -All' then a Java Control Panel applets from the Windows Control Panel with verbose logging. | |
| .INPUTS | |
| .OUTPUTS | |
| .NOTES | |
| The validation of Java Control Panel applets consists of 3 areas: | |
| NotInstalled: The Java Control Panel exists in the registry, but not on the file system. | |
| NotAvailable: The Java Control Panel exists in the registry and file system, but not in the Windows Control Panel. | |
| Available : The Java Control Panel exists in the registry, file system and Windows Control Panel. | |
