In my PC (a Lenovo Workstation) it's a tool for extended keys (lock desktop, my documents, etc) of my Lenovo keyboard.
Seems to cause games to minimize when started. They will keep minimizing until I kill this process.
Multi-function keyboard driver. Installed by ibm multimedia keyboard
SKDAEMON.exe is the drivers needed for the IBM Access Keyboard. If you remove this, your IBM Hotkeys will not function (i.e. Calculator, Email, Internet, Lock Desktop etc....)
whenever it runs it slows my machine to a crawl.
Starts my e-mail client (Thunderbird) by calling the Simple MAPI Client Daemon every time my computer starts up
it is always the file that is stopping my computer from running

Best practices for resolving Skdaemon issues

A clean and tidy computer is the key requirement for avoiding problems with Skdaemon. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
