Real player scheduler has a number of auto start execution points (Startup files (all users) run, Autoplay handler).

Run realplayer and go through all preferences and options de-selecting automatic "Updates". Realshed should not run then. If it is, try again but go through every option!!! Realplayer is destroying its own reputation by poaching CPU time from millions of PCs. Hope they go bankrupt.

When I was playing a game with Task Manager opened, I noticed the game slowed down and then looked at Task Manager. There were 135 processes, most from realplay.exe. When I ended realsched.exe, it turned back to normal. I deleted it on my registry and all's well now.

It make my computer crash after i upgraded/renew this thng!
It's nagware. How I got rid of it was go into "Task Manager" look for it in "Performance" and look for the "realsched" file, disabled that, went through my computer local disk C: real (The name of the file, for me) Shift + Delete, Yes to all. And then it's done. I read the rest of what others had to offer on these comments, as well, so if that doesn't work try the other's and good luck.

Best practices for resolving realsched issues

A clean and tidy computer is the key requirement for avoiding problems with realsched. 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.
