I just got it after 2 years, managed to get my laptop, which did not work anymore due to moisture, to run again! Now I do not know my former password and can't come in Windows.
What can I do, so that I may come in there with a new password?
If the data is not encrypted, you can simply connect the disk to another system as another disk and read it out directly.
Turn off the laptop, then start it again and when you start you take out the battery directly, then restore. Now you start the laptop against now should open a black window (Windows Troubleshooting).
