windows xp system32 error

windows xp registry error?

I have a registry error that must be corrected. I have step by step instructions from Microsoft to correct a mistake system32. Can someone who is not an expert set a record? I can do more damage?

while the other answers here you have several points, the main answer to your question is "YES" (both of these questions), should, however, to follow a few steps.) Save Record 2.) Can a set point for restoration, the worst three.) Read each step in the instructions three times 4.) Registry entries are too long, be careful reading of the screen 5.) I can find the software Ace Utilities AceLogix works well over a ton of easy tools for other tasks hope this helps
