What is issch.exe?

The genuine issch.exe file is a software component of InstallShield Update Service by Flexera Software.
The InstallShield Update Service is an optional component of InstallShield that software developers can include in their product installation. It runs in the background on the end-user's system and detects when the developer has made automatic updates available for their software product. It then automatically schedules a task to execute which will download and run the update installer. Developers do not always provide a configuration option that turns off this service for their application so Flexera has made available to end-users the Software Manager, which they can use to control the execution of the Update Service Scheduler with respect to a specific application. Flexera Software is an American company headquartered in Chicago, IL, originally formed as Acresso in 2008 (and renamed to Flexera in 2009) when Macrovision, (now Rovi), sold its software division to an investment fund. It provides application producers and enterprises with tools to construct software installation packages and monitor software licensing compliance. It is still backed by private equity although the majority interest is now owned by a division of the Ontario Teachers Pension Plan.

Important: Some malware camouflages itself as issch.exe, particularly when located in the C:\Windows or C:\Windows\System32 folder, for example TROJ_GEN.R08OC0OI516 or TROJ_GEN.R00XC0EGN16 (detected by TrendMicro), and not-a-virus:RiskTool.Win64.BitCoinMiner.awe or not-a-virus:HEUR:RiskTool.Win32.BitCoinMiner.gen (detected by Kaspersky).

It is not needed. Programs should be updated manually, not automatically, so the user may know what changed when a problem does occur. It is deceptive, as it is unclear which program installs the Install Shield Updater, and there is no record of the Install Shield Updater in add and remove programs.

It's good, runs in the background, and installs updates.

Configurable through the "Program Updates" icon in Control Panel. But even if you tell it not to update any program automatically, this process continues to run, even after reboot. Those who say it is safe likely work for (or are affiliated with) Macrovision. It's more of a nuisance than anything else. Personally, I disabled it by removing it from the registry. You can also use MSCONFIG... under the startup tab, unselect ISUSPM and issch.

Best practices for resolving issch issues

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