Ok, now the command prompt says:
C> "command : -java Xmx800m -jar "C:\Users\Jack\Downloads\Minecraft.jar"
'COMMAND' isn't recognized as an internal or external command, operable program or batch file.

I also tried it with the extension "Minecraft.jar.exe"  where I got:
Specified COMMAND search directory bad
Too many parameters
Too many parameters
Too many parameters
Too many parameters

and "Minecraft.exe", where I got the first error message (I have a copy of all 3)

I'm starting to hate my computer.  :)  Assistance?
If you like my posts, an internet would be very much appreciated :)

Seems to have worked for me, thanks!

Make sure that your file is Minecraft.jar and not Minecraft.jar.exe. Windows thinks that it's an exe called Minecraft.jar, and you want it to think it's a jar file so that Java can run it. To fix this, go into the command prompt and type "rename Minecraft.exe Minecraft.jar" in the directory in which you have Minecraft.exe. Then you can run your batch file like normal.

I got this message again when I renamed and attempted Minecraft.jar-

THIS IS THE ERROR:

Then when I ran the command with Minecraft.jar.exe I got this:

Too small initial heap

Still no clue, but patience is a virtue.  :Skeleton: I feel like a n00b...

Do you see the difference?:
java Xmx800m -jar "Minecraft.exe"
java -Xmx800 -jar "Minecraft.exe"
and
java -Xmx800m -jar "Minecraft.exe"

If not let me explain to you:
    [*:f3iml0pt] java Xmx800m -jar "Minecraft.exe"
    without hyphen makes java interpret Xmx800m as a class name which is not what you want
    [*:f3iml0pt] java -Xmx800 -jar "Minecraft.exe"
    set maximum Java heap size to 800 bytes which is indeed too small, even for initialization of VM
    [*:f3iml0pt] java -Xmx800m -jar "Minecraft.exe"
    set maximum Java heap size to 800 MegaBytes

Open notepad, write (cut & paste):
java -Xmx800m -jar Minecraft.exe
and save it in "C:\Users\Jack\Downloads", or wherever is minecraft.exe, as minecraft.bat

Run minecraft.bat from "C:\Users\Jack\Downloads"

Thank you very much, now I got atleast the game working. I don't get why it says I don't have accelerated openGL, my openGL is version 2.1. I really hope notch fixes that soon.

I've also noticed that with this workaround, my laptop only uses 3% allocated memory for minecraft, making the game a laggy ride until I set my view distance to tiny, which is rather annoying. Do you know how to fix this?

Didn't work for me either.
I have the "Unable to access jarfile" I even tried the .exe. Nothing works.

Intel® 82945G Express Chipset Family

I'm really beginning to think I'm never going to be able to play this.

I have this same problem, but doing that did not fix it. still says not a recognized command, operable program, or batch file.

i have intel graphics media accelerator HD

My error is different. When I type the command in I get "The filename, directory name, or volume label syntax is incorrect" I know the file name and directory are correct. I've inputed the command about ten times and get the same thing every time. I'm not sure what to do.

This worked perfectly for me. All other options that came before Mihai Manole's did not work for me. I'm using a lenovo thinkpad laptop. Thanks, and let us all learn from that.
