My girlfriend mentioned to me one day that she had forgotten the windows password to her laptop (she never used it) and asked me to take a look at it. The first thing I noticed was it was an HP laptop with fingerprint and face recognition as well as other annoying security features. I instantly thought this was going to cause problems, which turned out to be true. I'll try to be thorough and explain what I have tried to do so far.
First I thought I should sign into the Admin account, or any other account other than her own personal account, however her account was the only one available (even in safe mode). Then I went into the BIOS and reset the settings which I instantly regret, but hindsight is 20/20. After resetting the BIOS, under her username (at the windows login screen) it says "password not available". Next I went into safe mode and tried to click the forgot password button and used a disk I had made on my laptop, but of course this didn't work because it wasn't made on her own computer. I also tried a password reset disk which did not work either. I saw this trick online and tried it, http://pcsupport.about.com/od/windows7/ht/reset-password-windows-7.htm , and after doing this when I entered the "new" password at the Windows Login screen it says "Unknown Username or Bad Password." I then ran a restore point, I doubted it would do any good at all but It was worth a shot as I was running out of options. Next I tried using a password cracker program and it could not find the password to the account. My next option is completely re-installing Windows, however I Cannot access Windows on her computer so I can retrieve the product key for when I go to re-install it.
I'm at my witts end and have been digging a hole for myself with this situation. If anyone has any thoughts at all please feel free to comment, I'd really love to get this fixed as soon as possible because I'm tired of fooling with it haha. Thanks
