There are some strict limitations, some programs simply will not work. Use compatibility mode settings to manage compatibility in windows. You can right click the icon and hit troubleshoot compatibility

System lockups

If you are running an app in a system and it locks up you need to ask yourself "is it the app that caused it"? In general if an app is causing the system lockup it will do it at the same time every time. If an app keeps casing your system to shit, try a reboot, reboot into safe mode and uninstall the application. After this wait a while to see if your system is running fine to really zero in on the fact that it was the application. Before reinstalling the program research the app to see if people are having the same problem.

Missing service error

If you get this go to services and see if its running. After a reboot if it turns off again go to MSconfig and make sure its turned on the start up itself. If this doesn't resolve it, you need to reinstall the app that brought the service in the first place. If that doesn't fix it, use the internet to search for issues.

cmd. Allows windows to check its DLLS to replace any that are bad. If you still have the problem after this its means you installed an app and it didn't install a DLL; in this care reinstall it. If this doesn't work. Go find a DLL repository, search for the missing DLL online. Search, find forms, etc. sometimes windows will need you to register a DLL, in this case use regsvr32. Type the name of the program+regsvr32+DLL and windows will find it for you. Always make sure to always run malware bytes after downloading new DLLS .
