To delete a install in win 10 first delete the entire installation by using windows file explorer to the location you installed it. Usually program files (x86) / Microsoft Games / Microsoft Combat Flight simulator 3. Select it then delete,(be sure to empty recycle bin). Next,go to- Users -on your C drive and select your- *(name)*/AppData/Roaming/Microsoft/*(the name of your install)* ,then delete it. That should complete your uninstall. Hope this helps...
