I want to save %USERPROFILE% as a string read from regedit to a text file,but the cmd changes to "C:\Users\Administrator",does anybody know how to fix it? What I want is saves like this :

"%USERPROFILE%\AppData\Local\Microsoft" in a.txt

"C:\Users\Administrator\AppData\Local\Microsoft" in a.txt

The Code:

echo %USERPROFILE%\\AppData\\Local\\Microsoft >> c:\a.txt
                % is a deference operator for variable so you have to prevent the % it self. Try this: "%% you variable %%" . may be works.

                Also as you didn't answer the question referencing regedit, I can only assume you're writing the output for use as input to a .reg file. Are you aware that if you use reg.exe you can add the registry entry directly with the normal path, there will be no need to double up the back slashes for instance.

You double up the percents to prevent the expansion:
Echo="%%LocalAppData%%\Microsoft">a.txt
Also, notice the changed environment variable, which defines the location you were looking for.
                I just want to get the regedit string value and then save it to a text via cmd,and want it keep as the same as regedit string.

                There was nothing at all about regedit in your question. Please update your original question with the real task and details, so that we can provide a more specific response.

Update Solution
Finally,I find a solution myself,thanks for all kindly help,the codes here:
Set _a=%
Set _b=USERPROFILE
Echo %_a%%_b%%_a%\\AppData\\Local\\Microsoft >> c:\a.txt
There will be works correctly in any machine,hope this can help someone who needed it like me.
In general, precede an awkward character like &<> etc., with a caret ^ to use echo to show it.
Naturally, % is the exception. You need to escape % with % thus : %%
                Thanks for help,you meant:echo %%USERPROFILE%%\\AppData\\Local\\Microsoft >> c:\a.txt?Am I wrong?the output text is %C:\Users\Administrator%\\AppData\\Local\\Microsoft

                echo %%USERPROFILE%%\\AppData\\Local\\Microsoft >> c:\a.txt  produces %USERPROFILE%\\AppData\\Local\\Microsoft in the file on my machine...
