A guy came to me with his computer and couldn't get access because his password wouldn't work. Some people forget but sometimes the password info may get corrupted and not be accepted.
There are any number of ways of bypassing this issue, I found a simple CD/DVD/USB solution from:. http://www.lazesoft.com/forgot-windows-admin-password-recovery-freeware.html
So download the Lazesoft Recover My Password Home Edition. Install and run it.
Open program and click on the big Burn Bootable CD/USB Disk Now! button.
Then click on and select the operating system your trying to get into. Just a tip, I'm not sure if this program is as system specific as it seems. I mean I used Same as this computer (Windows 7 64bit) for my choice but still was able to use it remove it from my test computer with Windows 7 32 bit.
Then you get a updating system information... message, just wait.
Then you get taken to a window to select what media you want to use. Originally I chose USB Flash but the program kept crashing on me. So I chose ISO image instead. It shows you the path and name of the finished ISO if you don't change it. I left it as is.
Click on the Start button.
Finally, you will get a message, The ISO image was created successfully.
Then I needed to burn of the ISO to CD. I was going to use a program to transfer this image to a USB and make it bootable but decided to burn it of on CD to give it a test run. If you plan on using a CD/DVD just choose the CD/DVD option in the media selection window.
Now to try it out.
First, if your trying to boot off this CD/DVD/USB from a computer that came with Windows 8 or 10 pre-installed, you may have to disable secure boot first.
Unfortunately, I can't help you much in this department, you'll have to do some research for your particular system. On the Acer that was bought to me, not my own, if I remember correctly, I had to go to Authentication tab in the BIOS and disable Secure Boot. Then I had to go to the Boot Options and set Launch CSM to Always. And I'm sure in those boot options somewhere was one to set boot menu to legacy mode.
Otherwise pressing F12 in the case of Acer to get to the boot menu would only show the option of Windows Boot Manager.
So once all is said and done, boot of the CD/DVD/USB. Choose Lazesoft Live CD [EMS Enabled] and press enter.
Sorry about the awkward screen shows taken from my camera. Trying to get a good angle with no glare from my monitor.
Then it loads files. Wait. It will open to a basic desktop screen and the password recovery program should open automatically.
Just click on Next.
It should automatically detect your system and the option Reset Local Password is already set. Click on Next.
You'll get a message it's for non-commercial use, just click on Yes.
Pick your account listed and click on Next.
Your account should be listed, click on the RESET/UNLOCK button.
Then, if all went well, you should get a reset successful message.
This takes you back to the program interface just click on Finish. This takes you back to the basic desktop. At this point you should have already been backing up your system but if not, double click on the Lazesoft File Manager, stick in a flash or external hard drive and use it to backup your files...NOW. We'll wait. :-)
Otherwise, click on the start button and reboot your system by clicking on Reboot Computer.
Before rebooting I got a message to SAVE DATA BEFORE REBOOT. Just click on OK.
Congratulations, your now an hacker. Your diploma's in the mail. :-) It's not a crime to hack into your own computer or someone else's computer If you got their permission. It's only a crime if you hack someone else's computer without their consent.
Just a few other notes. If you use a Microsoft account not a local and can't sign in, try this:
Make sure you got you got a Internet connection. If your not using a local account your computer needs an Internet connection to verify your account.
If your using a Microsoft account and can't sign in, go to www.outlook.com and see if you can sign in by putting in your email and then password as required. If you can't sign in then you'll have to use the forgotten password option that will appear and jump through Microsoft's hoops to reset your password.
If you can sign in, try this CD/DVD/USB anyway. I had to do this once on a Windows 8 computer awhile ago, I'm not sure if I used the same program or not. It didn't erase the password but it did clear out the sign-in issue so the password would work.
