It is the auto software updater for Dragon Naturally Speaking. When it is time to update, it will consume more and more RAM until you shut it down, even when there are no updates available. It isn't "dangerous" except that it will slow down your computer. Try setting updates to "manual" before trying other methods of removing it.
I did get Nuance PaperPort 12 so it likely installed with that. Based on my poking around, it is probably harmless except for taking up some space & memory, which is enough reason to delete it, or at least disable it (I prefer SysInternals' "AutoRuns" for that). BTW, if you also have Nuance PaperPort, I'd recommend checking out that SysInternals' "AutoRuns" I mentioned. Also installed by Nuance and run at logon is: IndexSearch, PaperPort PTD, PDF5 Registry Controller, PDFHook, besides ISUPM and agent. Then there's the service PDFProFiltSrvPP. All that combined probably takes a lot of space!

The Macrovision Installshield Update Service installed via a CorelDraw application on my laptop. I was only able to remove the complete folder using the "Unlocker" freeware, and then ran a registry cleaner which deleted about 350 associated entries. Corel still runs and can be updated manually via its help bar, once it is started. What gets installed without my permission, I consider malware.
It comes packaged with many products. It isn't necessary to the application only an updater for Nuance software. I wouldn't leave it because it is just another program taking up resources.
Totally intrusive scanning of all my running software and annoyingly pops up with messages on what supposedly needs updating. Is this a way of Flexera trying to penetrate the Software Asset Management market in a sneaky way perhaps?
windows installer keeps launching it over and over. We end task it and it comes right back. We had WinDVD and it did not uninstall clean! ARRRGGHHhhhhhhhh
This is a memory hog. It is resource intensive. It is spyware. Nuance bundles it with Paperport and other products. If you are a registered owner of Nuance Products complain to them. I believe it is spyware looking for hot software. There are better ways of forcing purchase than this BS

i am summarizing all the comments into this one. "it runs at startup, then makes itself invisible. No respectable software should do that." "cannot easily uninstall, ... does not ask permission before installing thus fills every definition of malware." the fix: (i am running xp) run regedit, navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and deleted the key ISUSPM in C:\Documents and Settings\All Users\Application Data\FLEXnet\Connect\11 make each of agent, dwusplay, isdm, issch, and isuspm a null file, then hid and write protected them. i used notepad's 'save as' option with save as type 'all files' to overwrite them. open a command window: C:\Documents and Settings\All Users\Application Data\FLEXnet\Connect\11 attrib +h +r +s isuspm.exe for each of the offending applications. delete the contents of windows/prefetch, where you'll find the only copy of isuspm.exe note: you may have to do this under safe mode if you get an 'access denied' error message note: i used this same process to get rid of the annoying java update popups. the only way to get rid of jusched and jucheck, as unchecking the update checkbox is futile. hope that helped.

Best practices for resolving ISUSPM issues

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

To help you analyze the ISUSPM.exe process on your computer, the following programs have proven to be helpful: ASecurity 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. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
