I have a company laptop which I have used in several locations to work remotely (rentals, my sister's, etc). Now I have brought a router to install at my sister's and to my surprise she lost the info on the username/pass her ISP provided her. Without going into much trouble calling the ISP (in 8h I have to start working), I ended up doing what I write in this instructable.
I didn't know another place where people can post such "tutorials" or "tips and tricks" which is free of logins so I posted here, hoping it will show up in the search engines' results for others with the same issue.
Hope it helps.
Step 1: Download Dialupass From Nirsoft
Don't trust me? ->
Step 2: Antivirus Detects It As a Threat
If this situation happens to you as it did to me, there is not much you can do. Depending on your antivirus, you could disable it temporarily or chase the process and kill it. I couldn't for my laptop is a company-provided one and I don't have privileges to kill this particular process.
So my solution was going into SafeMode.
Step 3: Go to SafeMode With Networking and Run the Utility.
I never remember the F Key at bootup to show me the booting options so I pressed the power button (hard reset) until the laptop shut down.
Note: on Microsoft support websites you will find this info:
Do one of the following:
If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
Step 4: Copy the Relevant Info and Use It for Your Own Intention
Because I needed this password from my laptop so I setup my router, I entered the SafeMode with Networking. For whatever reason you might want to recover the PPPoE passwd from an existing Windows you might be ok with normal SafeMode.
After running the utility I right clicked on the line with the PPPoE username/passwd, select to copy the fields and filled the appropriate fields in my router's setup.
Now I am online and I am writing this :)
