| # LCore.exe (Logitech's tool for configuring and customizing their devices) has a pretty bad memory leak. | |
| # This script kills LCore when it starts using more that 256MB, cleans up the task tray, then restarts LCore. | |
| # It uses the same command line used to initially start LCore. | |
| # Set LCore to start when Windows starts. | |
| # (If you need to start it manually, include the /minimized argument: LCore.exe /minimized ) | |
| # Save this file to %USERPROFILE%\command\reset-LCore.ps1 | |
| # Create a Task Scheduler item with triggers for: | |
| # every hour after logon, and | |
| # every hour after created or modified. | |
| # Set action to: | |
| # Program: %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe | |
| # Arguments: -WindowStyle Hidden -ExecutionPolicy Bypass -File %USERPROFILE%\command\reset-LCore.ps1 | |
