How to change my Java (32 bit) to Java (64) on my Windows 8 i7 64-bit?

I'm having a hard time with my Windows 8 during programming as well as playing Minecraft. My software keeps asking me to get 64-bit version of Java. But every time I try to change it from the oracle website. My computer still say it is 32 bit version. How can I replace the Java and have it on 64 bit? I always update my JRE and anything that has something to do with Java/Oracle. Can you guys help me out?

How to uninstall CROSS BROWSE?

I didn't even want this program in the first place. My little brother tried to download Minecraft Premium for free he ended up installing many viruses including crossbrowse. I unistalled all of the programs but crossbrowse. I tried uninstalling it via control panel but it is always saying "please close all crossbrowse windows and try again" even though nothing is open! I have also gone into my files and manually deleted it.
Please DO NOT GIVE ME A CLEAN UP DOWNLOAD

Do you need Java installed in order to run Adobe Photoshop CC and some programs?

I'm planning to uninstall Java because I think I don't need it anymore. I had it installed a year ago because I wanted to play a game called Minecraft. I already quit playing Minecraft and stopped playing games months ago.

I was thinking of uninstalling Java because I think I really don't need it. Now I was wondering if I need Java to run some programs such as Adobe Photoshop CC. I frequently use Photoshop now and then as I try to improve my photo editing and graphic designing skills. I once read a user's question saying why Photoshop CS5 needed Java. Is it even needed?

Here's a list of programs I use. I don't know if one or more needs Java installed:
: Adobe Photoshop CC: Paint.NET: Inkscape: Google Chrome: Spotify: iTunes: VLC Media Player: WinRAR

I also heard that Java is not safe anymore, is it true?

Computer crashes when I play games?

So my laptop randomly shuts off on 2 conditions:
1. I haven't used it for a while
2. I'm playing games on it

So if I was to play something like ROBLOX, my computer crashes. If I played minecraft, however, my computer crashes in like 20 minutes.

My laptop is not overheating because I cleaned it less than a week ago. My best guess is because of a malware virus, but I'm not certain. I really need help. This problem is irritating me and it annoys me and sometimes, I feel like I need a new laptop. What do I do?

Minecraft world won't load?

Ok so I have been working on a world for a few days now, and I came across this unloaded space in the map. I thought that proceeding to go inside would fix the problem and load the chunks. But instead I got stuck inside it, to where all I could do was look around. So I quit to title and tried reloading the map and it brought me to what I'm showing you in the photo. The map won't load. I can access my inventory but I just keep slowly falling down into nothing. Please someone help me with this, I really don't want to lose this map. Minecraft world won t load
