How to use the reg command line statement

There is a small batch file I would like to execute. I have cut and pasted it from another source.
The batch file failed repeatedly.

Then I attempted to run the statements individually at the command prompt.
Things still failed.

Example:

reg load HKLM\MY_SYSTEM followed by a command in " " marks needs my machine name which is msi64-PC. The machine description is msi64.

But the statement bombs and says pretty much it can't find any part of the statement that is correct.

I can copy out the exact error if needed. But the problem seems to be I'm not pointing at the right thing in the first place or there is a directory conflict.

The sequence is

reg load MY_SYSTEM followed by " a command statement to "0Windows\System32\config\system" in quotes

reg delete followed by what to delete

reg unload which is MY_SYSTEM (to get out of the command)

All of these fail.

I should be able to run the load command at least with no argument from Win7

that statement from the sample looks like this:

reg load HKLM\MY_SYSTEM "%~dp0 (zero)Windows\System32\config\system"

I can add the error at a follow up

I'm concerned about the content. Don't want to break any rules here.

The first line should be able to be run error free. Can you do that and maybe post a screen shot?

Whenever I see tildes and percent signs I think something is truncated and incomplete.
Are these legitimate characters would be a start.

Add a pause command as the last statement in your BAT file.
That will keep the CMD window open so you can upload a screen print of the error you see into your SF post.

From the OP, I wonder why your "0Windows\System32\config\system" statement has the 0 in Windows,
maybe that should just be "Windows\System32\config\system"

Are you sure the source you copied this batch file from is reliable and trustworthy ?

If the Oh or Zero in the statement looks like an error I can certain hand enter it
without and see what happens. It's on the original work.

I will get you the screen shot or text of the error tomorrow is the soonest.
This is no big emergency.

Any entry I make should have _what_ at the MY_SYSTEM statement? I still don't know
what the author of the .bat meant.

The batch file with errors is shown in the attachment. Moderators can say if it violates any rules. The purpose of the bat file is reset the ability to rearm Win7.

A certain number of rearm commands as in SLMGR -REARM are allowed after which an error issues.

Just now I noticed some strange character at the command screen in the first line. The first line and naming conventions of what was the generic MY_SYSTEM given in the original and described earlier above have the errors.

Lastly if Win7 has a tutorial on the rearm problem and it has been addressed already, please advise.
