It's meant to be a task scheduler. It can be used to set up all sorts of automated things in your system. But of course it can also be a loophole for all sorts of fun and funny viruses, such as "potato farmer", which lags your system by putting HUGE files named potato on your desktop, or ones that play creepy music when you don't want it to, etc etc
When used in conjunction with the at.exe command, both of which run with system level privledges, a bad guy could do all sorts of nifty things, like allowing lateral movement within a network.
its task scheduler

Don't delete this file if its where it should be. (Sys32). It will slow things down if you're on the net and its running. I temporarily disable it with Winpatrol. Should only be one instance of this running, if you have 2, it could be Malware Etc'.

Run's timed app's !!! past in run: %SystemRoot%\system32\taskschd.msc /s And you can alter these app's (funny pages,urls, updates, etc....
i used control alt delete after i deleted it on task manager and it works normal my computer doesn't see it coming up any more
could be used to host malware, however could also be used to contain task scheduling DLLs related to Windows 7. Use process explorer to examine the DLL and Handles (opened files, mutex , etc ) it has in order to inspect anything suspicious If it consumes too much CPU, dump it and inspect it and then kill it

Best practices for resolving taskeng issues

A clean and tidy computer is the key requirement for avoiding problems with taskeng. 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 doing a repair of your installation, or in the case of Windows 8, 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 taskeng.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.
