hey, I found such an easy way to backup your databases on MySQL if it crashes. First, take the folder data from mysql dir, then copy it where ever u want it, then its backed up. To restore, replace the old fiolder with the new! my mysql crashed and i did this and i was like WHOA! All my users and databases were restored. Oh yeah, to delete the mysql service, the key to servicesw is /HKEY_LOCAL_MACHINE/SYSTEM/CurentConfig/services , delete the mysql folder, and bingo ( u have to do this to reinstall mysql, i learnedf that the hard way
lol
