First and foremost, I would like to say that in most cases, you should NOT attempt to do this if you are not confident with what you are doing. It is a simple process, yet if you accidentally delete something you are not supposed to, it can have detrimental effects on your system. Always try removing java from the "Uninstall Programs" section of the Control Panel before attempting manual removal of any program.
If you do this, you do so at your own risk. I, nor anyone on this site, take any responsibility for your actions.
What you will need:
the most up to date version of Java JRE from http://www.oracle.com/technetwork/java/javase/downloads/index.html
a registry cleaner (I use ccleaner)
an account with ADMINISTRATOR privileges.
Step 1: what to delete
the follow directories should be removed first if they exist
C:\Program Files\Java
C:\Program Files (x86)\Java
after deleting these folders you must navigate to your %appdata% folder
in the search under the start menu, type in %appdata% or appdata depending on your version of windows.
the following directory should be removed from appdata
AppData/LocalLow/Sun
now there a few other java files located in the system32 and the sysWOW64 that are not required to be removed nor will i list them here. if they really need to be removed, then you are very much doing something wrong or are a programmer and know when/if they need to be removed. just know removing anything from these two directories can cause your system to be unstable so as i advise against it as installing a newer version of java actually overwrites these files instead of making a new instance of the JRE as it does with the above three locations.
step 2: restart your computer

step 3: edit your registry (optional-ish)
editing the registry is not for an inexperienced user. modifying the registry in any way can severely muck up your system if you do it wrong. If you choose to do this: i advise using a professional registry cleaner like ccleaner. simply run the cleaner, making sure you create a system restore point when asked.
step 4: repeating steps 2 and 3 (if you did step 3)
typically, registry cleaners do not find all registry errors until they have been run 3 to 4 times. repeat steps 2 and 3 until there are no registry errors found.
step 5: installing java
if you have not already, download the newest java jre from the link above. be sure you are downloading the version needed for your processor. x86 for 32 bit systems and x64 for 64 bit systems. run the file.
step 6: restart your computer
yup, again. this is the last one though.
Congrats! You've manually removed and updated your java! This should solve any problems with the occasional "leftovers" from updating java a lot. hopefully you didn't accidentally delete anything else.
