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 cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the SKDaemon.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
