Registry value per batch editing - Windows XP error

Hello,

I would like the value of a registry keys using a batch file to edit. It already contains and may not be overwritten. They must be maintained and I would like to add something.
The problem is the existing value on each machine is the same, however, it is the added.

I approached the value of the Keys which was reading out it in a store variables and a new variable to define the variables from the old and the new value is composed.

So looking from the batch so far:

Code:

---

@ echo off
 
  set RegHotfixListe = "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Test"
  set HotFixNr =
  set new =; Value2
  set f = 
 
  for / F "delims = \ tokens = 7"%% f in ( 'reg query "% RegHotfixListe%" / v name 2 ^> NUL ^ | findstr "name"') do "%% f"
  set HotFixNr =% f%%% new

  reg add "RegHotfixListe%%" / v name / t REG_SZ / d "%% HotFixNr" / F

  break

---

Problem is the existing value does not read, or not in the variable will be stored. Find findstr instead, I had already tried initially. So I have the key "test" only "; Value2" and the already existing has been overwritten.

According to research, it should actually do so, but it will not. I am on the boardwalk or the script is just a small mistake?

Easy way: just try out, if you're in reg query "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Test" | findstr "name" ever get out the value that you are looking for. I'm getting there even with no value back.

With reg query "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \" Although I get a lot of information, but I've no subkey with the name test. Use I think so: | find / i "name" I get a result back, at least in the Reg-Key, where I just try.

Code:

---

C: \ WINDOWS> reg query "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVe
  rsion \ Test "| findstr" name "
      name REG_SZ; Nokia

  C: \ WINDOWS>

---

I have the keys and key extra-created course, as exists in Windows do not. find / i is the same.
So I have read the works already, but the saving is in the variable.

What do you want to

Code:

---

do "%% f"

---

achieve?

How about

Code:

---

for / F "delims = \ tokens = 7"%% f in ( 'reg query "% RegHotfixListe%" / v name 2 ^> NUL ^ | findstr "name"') do (
  set HotFixNr =% f%%% new
