Try to reset the admin password following below link

How to reset the admin password in AEM 6.3 | Adobe Experience Manager

but fail and shows that  WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.
Found admin node: SegmentNodeBuilder{path=/home/users/D/D4z92KBRNNErnNt3l1yf}

How can I reset the admin password in this case?

Hi @JunjieLu , you will need to run the script as admin. Also, please feel free to post this in the AEM community.

hi @JunjieLu ,

I tried this in my local for AEM 6.5 it worked perfectly.Please follow the below steps:

a) Download the Oak-run*.jar. I used

oak-run-1.68.0.jar 

from this path https://repo1.maven.org/maven2/org/apache/jackrabbit/oak-run/1.68.0/

b) Download the groovy script from https://helpx.adobe.com/content/dam/help/en/experience-manager/kb/How-to-reset-the-admin-password-in... and save this file as "admin-reset_groovy" remove .txt extension.

c) now from the folder you downloaded the above file run the below command as per segment store location

java -jar oak-run-*.jar console C:\software\crx-quickstart\repository\segmentstore --read-write ":load admin-reset.groovy" 

d) the script auto changes your password to admin as shown below:

C:\software>java -jar oak-run-1.68.0.jar console C:\software\crx-quickstart\repository\segmentstore --read-write ":load admin-reset.groovy"
Apache Jackrabbit Oak 1.68.0
Found admin node: SegmentNodeBuilder{path=/home/users/s/sv54fUZ_7dxIUK6dNxGm}

Hope this helps.  If possible move or tag this ticket to Adobe Experience Manager instead of Adobe experience Platform.
