text: oracle 9i :  please  help!? how can i prevent oracle.exe to run automatically on windows startup? it consumes a lot of memory and makes my computer respond too slow to work . i tried tuneup , windows defender , etc to disable its automatic startup  ---but no options available there for the program. go to start > run > type msconfig and click ok. go to startup tab and uncheck oracle related entries. similarly go to services tab, check the box "hide all microsoft services" then the list will show you fewer services, you can uncheck the oracle one.
