How to Bypass Windows 8.1 Password on Lenovo Yoga Laptop?

Before getting started, you need to make a PCUnlocker Live CD on an alternate computer. Download the zipped ISO image of PCUnlocker and extract it. Next burn the resulting pcunlocker.iso file to a blank CD (or USB stick) using the ISO2Disc program.

Put the CD in the CD drive of your Lenovo Yoga laptop. To get the laptop to boot from CD, we need to go into the BIOS and switch the Boot Mode from Unified Extensible Firmware Interface (UEFI) to Compatibility Support Mode (CSM). When the computer is off, press the Novo button and then select BIOS Setup.

In the BIOS Setup Utility, go to Security tab, and disable the Secure Boot option. Next, on the Boot tab, change the Boot Mode from UEFI to Legacy Support. Save the changes and exit BIOS. Shut down the laptop and then press the Novo button again and then choose Boot Menu. Choose to boot from PCUnlocker Live CD.

The laptop will load the WinPE OS from CD and open up the PCUnlocker utility. At this point the program can directly access the Security Accounts Manager (SAM) database and extract all your Windows user accounts.

Select your user account and click on “Reset Password” button. The program will reset your forgotten password by modifying the stored password hashes in the SAM registry file. Restart the computer and take out the CD. You can then log back into your Lenovo Yoga Windows 8.1 laptop with a blank password!

After the release of Windows 8, most of the new laptops and desktops are shipping with Windows 8 pre-installed. If you’ve become accustomed to Windows 7 and don’t like Windows 8′s new Metro UI, you can downgrade to Windows 7. Windows 8 Pro comes with a feature called Downgrade Rights, which means you can downgrade from Windows 8 to Windows 7 without paying a penny or having to format the hard drive.

If you want to try this, just make sure your new computer has downgrade rights because not all Windows 8 computers are on the list. These rights are available to PCs which come with Windows 8 Pro pre-installed and not for users who have upgraded to Windows 8 using the promo offer. So it is basically only Windows 8 Pro OEM users. You can only downgrade to Windows 7 Professional or Windows Vista Business, not Windows XP. To learn more about downgrade rights, please check out this complete guide from Microsoft.

Tips: You might need to provide your Windows 8 license key for validating your purchase during exercising your Windows 8 Pro downgrade rights. If you’ve lost the key, you can use KeyFinder Plus to recover it from your current Windows 8 installation.

How to Downgrade from Windows 8 Pro to Windows 7 Pro?

The actual downgrade process is tricky and not a straight forward one. You first need to create a recovery drive for your existing Windows 8 in case you want to bring it back to Windows 8 in future. Once done, you need to disable UEFI and enable Legacy/CSM boot support. You will need a Windows 7 Professional DVD. Insert the Windows 7 installation DVD and boot to it. During the Windows 7 setup, you might need to enter the license key to go past the installation. Here you can enter any used Windows 7 key since activation does not happen here.

Now wait for the install process to complete. Once the process is complete, your PC might show activation failed message or it will not be activated. This is because you have used a key which is already in use. For getting a new key, you need to call up Microsoft support and explain to them about your downgrade rights. Have your Windows 8 Pro key ready which you’ll need to prove your PC has downgrade rights.

Once this is validated, you will receive a new activation key for Windows 7. You will need to do this for all PCs which you have downgraded. You can install back Windows 8 anytime using the recovery drive.

Every time you start Windows you’ll be prompted to enter the username and password for logging into your account. Though this is such a routine part of the day that is is easy to not even think about the logon process, things can go wrong for various reasons. In this article we’ll discuss how to troubleshoot the most common Windows login problems you might run into.

Issue 1: I tried to log on, but I keep getting a message telling me that the user name or password is incorrect, or Windows account is locked out

Here are several possible solutions to fix this problem.

• Caps Lock might be on

  Passwords in Windows are case-sensitive, which means that every time you type your password, you have to capitalize each letter in exactly the same way that you did when you first created it. If you have accidentally pressed Caps Lock, then you’re inadvertently typing your password in all capital letters. Make sure Caps Lock is off, and then type your password again.

• NumLock key might be enabled

  After enabling the NumLock feature, you’ll find a strange problem and you can’t type normal anymore. For example, when you type in “mjkluio”, your computer would type “0123456″. To turn off NumLock, please check out this article: 3 Methods to Disable NumLock on a Laptop Keyboard.

• You might be typing the wrong password, or forgot your password

  If you can’t remember your password, you need to reset your password, either with a password reset disk, an administrator account, or a third-party Windows password recovery tool such as PCUnlocker.

• You might be trying to log on to the wrong user account

  If you have more than one user account on the computer, make sure you’re logging on to the account that matches the password you’re using.

• Windows account is locked out

  If you’ve enabled the account lockout policy, the Windows account will become locked out after a number of invalid login attempts. The account lockout duration can range is from 1 through 99,999 minutes. A value of 0 specifies that the account will be locked out until an administrator explicitly unlocks it. If you need to access your locked account urgently, PCUnlocker can be of help!

Issue 2: My computer is part of a domain and I want to log on to a local user account, not my domain account

To log on to a local user account on your computer, you need to know the name of your computer and the user name for the account that you want to log on to. To log on to a local user account, follow these steps:

1. On the Windows login screen, click Switch User.
2. Click Other User.
3. In the user name field, type the name of your computer, a backslash (\), and the user name for the account that you want to log on to. For example: computer name\user name
4. Type your password, and then press Enter.

Issue 3: The user profile service failed the logon. User profile cannot be loaded

Corrupt user profiles are a frustratingly common problem with Windows. When you type your password and press Enter, you will typically see the error message “The User Profile Service failed the logon” and “The user profile cannot be loaded”, and you’ll be returned to the logon screen. Here is a quick registry trick to fix your corrupt user profile.

Issue 4: User account not showing up on login screen

User account is not showing up on Windows Welcome screen? If your account is disabled, it will disappear from your Windows login screen. If you’ve enabled your account but it still doesn’t show up at the login screen, please check out if this registry trick is applied on your system: Hide User Account from Welcome Screen in Windows 8/7/Vista/XP.

Issue 5: Keyboard and mouse stopped working at login screen

Sometimes when the computer boots to the Windows login screen, you might find that the keyboard or mouse stopped working and you can’t type anything. If you’ve ran into this issue, this article should be helpful for you: Keyboard Stop Working at Windows Login Screen.

Got a Windows 7 PC and want to install Windows 8.1 as a second operating system for dual-booting? All you have to do is create a new partition for Windows 8.1, then install it. But what to do if you don’t have a spare partition to do this? In this post we’ll learn how to install Windows 8.1 into a virtual hard disk (VHD) and dual boot Windows 8.1 on a Windows 7 PC, without partitioning.

How to Use VHD to Dual Boot Windows 8.1 on Windows 7 PC?

1. Boot your computer from Windows 8.1 installation DVD or USB drive. If you have a Windows 8.1 ISO image, you can make a installation disc from the ISO image using the freeware ISO2Disc.
2. After a few minutes, you’ll see the Windows Setup screen. Pick a language (U.S. English is the default), and click Next.
3. The next screen allows you to install or repair Windows 8. Press Shift + F10 to open up a Command Prompt.

4. Now you need to use the diskpart utility to create a virtual drive that Windows 8.1 will be installed on. Type diskpart and press Enter to open the command-line disk partitioning utility.
5. At the diskpart prompt, type the following commands, pressing Enter after each one:
   • list disk
     This shows your currently attached hard disks. In this example I only have one, Disk 0.
   • select disk 0
   • list vol
     Show all the volumes that exist on that disk. You need to know the drive letter that you want to store your VHD file on.
   • create vdisk file=c:\win8.vhd maximum=10000 type=expandable
     This creates a dynamic VHD that can grow to 10GB in the root of C:\ drive. If your partition is smaller than 10GB then be sure to use a smaller value for maximum that is less than your actual partition size.
   • select vdisk file=c:\win8.vhd
     After selecting this vdisk, the following commands will apply to it
   • attach vdisk
     The VHD will be mounted and the disk will be available to the windows installer
   • exit

6. You can now click Install Now button. Accept the Licenses agreements. On the next screen select Custom: Install Windows only (advanced).
7. At this point, Windows Setup will prompt you to choose where you want to install Windows 8.1 and you can now select your virtual drive, which will be designated as Unallocated Space and be the size that you specified. As you can see in the screenshot below, I have selected my 10GB VHD. Keep in mind that when you select the VHD, you’ll see a Warning message that says that Windows cannot be installed to this disk. Just ignore it and click Next to continue.

8. When the installation is complete, Windows Setup will reboot your system one final time and you will then see the new Windows 8.1 style dual boot screen shown as below. As you can see, Windows 8.1 will automatically launch in 30 seconds if you don’t choose Windows 7.

That’s it!

While pressing the Power button, hold the volume down button until you get to the Boot Device Menu screen. From there select Enter Setup. In the BIOS Setup, select the Security tab, disable Secure Boot and Default Key Provisioning.

Navigate to the Boot tab. Under the Boot Option Priorities section, set your USB flash drive as the first boot option. Save your changes and exit BIOS.

The tablet will restart and boot from your created USB drive. After a while, you’ll get to the PCUnlocker program which automatically locates all Windows accounts on your tablet. Choose an account and click on Reset Password. It will bypass / remove your forgotten password in no time.

2. Then download and launch ISO2Disc, which is a really simple piece of software that helps you burn an ISO image to a disk (CD or USB drive). Locate the PCUnlocker ISO image and select GPT (required for UEFI boot), click the Start Burn button to create a bootable USB drive. If you’d like, you could also create a bootable CD instead.

3. HP Omni 10 tablet doesn’t come with a full sized USB port. To connect a USB drive to your tablet, a OTG cable is required. Now you need to boot your tablet from the boot disk you’ve created. Hold the Volume down button and then press the Power button to turn on your tablet until the Boot Menu appears. Select your USB drive and press Enter.
4. Now your tablet will boot from USB drive. When the PCUnlocker program launches, it will display a list of user accounts that are stored in your Windows 8.1 SAM registry file. Choose an account and click on Reset Password button. The program will reset your forgotten password instantly.

5. Restart your tablet and disconnect the USB drive. You can then log on to your HP Omni 10 tablet without typing a password!

Just bought a new Asus Zenbook which came preloaded with Windows 8 but you’ve lost the password? A forgotten password is no need for panic. As long as you have a password removal utility, you can get back into Windows 8 or Windows 7 Ultrabook in minutes. PCUnlocker is one of the best recovery tools that can help you get rid of forgotten Windows 8 or 7 password with ease. The following is a walkthrough of using a CD to reset Windows 8/7 admin password on ASUS Zenbook Prime UX31A.

First of all, you need to make a PCUnlocker Live CD using a secondary computer, not your locked PC. Download the ISO image of PCUnlocker and burn it onto a blank CD with your CD burning program. If you don’t have one, try the freeware ISO2Disc or ImgBurn.

Once you’ve created a PCUnlocker Live CD, put it in the CD drive of your locked ASUS Zenbook laptop. Power on the machine and repeatedly press F2 key to enter the BIOS Setup. Go to the Security tab and disable the Secure Boot Control option. Navigate to the Boot tab, disable Fast Boot and enable Launch CSM. Press F10 to save and exit.

Press and hold ESC key to launch Boot Menu when the computer restarts. Select the CD drive from the list and press Enter to boot from it. After a while, the PCUnlocker program will launch and it shows you a list of local accounts for your Windows 8/7 installation.

Select the administrator account and click on Reset Password button. This will unlock / remove your ASUS Zenbook login password immediately. Take out the CD and reboot, you can then get back into your Windows 8/7 system without entering a password!

Conclusion

After enabling the CSM (Compatibility Support Module) on your ASUS Zenbook, the UEFI firmware will run as an emulated legacy BIOS. If you need to create a UEFI compatible CD, you need to use the Enterprise edition of PCUnlocker which can boot in UEFI mode, without requiring you to enable CSM support.

How to unlock your computer after you’ve forgotten Windows 8.1 password? PCUnlocker is a powerful bootdisk that allows you to crack Windows 8.1 password on a computer where you forgot your password. The step-by-step guide below should work for Windows 8, Windows 8.1 and earlier versions of Windows.

How to Crack Windows 8.1 Password with A Bootdisk?

After you download PCUnlocker, you have to burn it on a CD by right-clicking the ISO file. If you don’t have an optical drive and you want to boot from a USB flash drive, you can use the free tool ISO2Disc.

Next, you have to ensure that the CD or USB flash drive comes before the hard drive in the boot order of your BIOS settings. Most PCs allow you to access the PC setup by pressing F2, F12 or Del right after you turn the PC on. If your computer comes with UEFI firmware, you might also need to set your PC to boot with Legacy BIOS mode instead of UEFI mode.

After you boot PCUnlocker, you should see the following screen. If you have more than one Windows installation on the computer, be sure to choose the correct SAM registry file for your target Windows installation.

Choose the user account where you want to reset the password, click on Reset Password button. This program will remove the existing login password and unlock your account in case it was locked out or disabled.

The password cracking process is now completed. Reboot your computer and take out the CD or USB flash drive. You can then login to Windows 8.1 without the need of a password!

In my previous post I detailed the method to restrict logon hours for any Windows account, so you can control when a certain user account is allowed to log on to the computer. If the user tries to log in during restricted hours, the system will fail the logon with the error message “Logon failure: account logon time restriction violation.” or “Your account has time restrictions that prevent you from logging on at this time. Please try again later“.

However, improper logon time restrictions might also cause you locked out of all Windows user accounts. Luckily there is a rescue bootdisk called PCUnlocker which can help you bypass the account logon time restriction easily! This program is mainly used by users to reset lost Windows password, but it can also remove logon time limits for local/domain administrator account on any Windows PC.

Here is step-by-step tutorial to help you bypass the account logon time restriction that is set through the net user /time command, built-in parental control in Windows, or Active Directory Users and Computers snap-in.

How to Bypass Logon Time Restriction on Windows Local/Domain Account?

After you download PCUnlocker, you have to burn it on a CD by right-clicking the ISO file. If you don’t have an optical drive and you want to boot from a USB flash drive, you can use the free tool ISO2Disc.

Now you need to boot your locked PC with the CD you just burned. Insert the CD into CD drive and turn on the machine. If your computer still goes straight to Windows login screen, you may need to enter the BIOS Setup utility and change the boot order to CD/DVD drive first, HDD second.

After you’ve booted into the CD, you’ll be presented with the PCUnlocker screen which displays a list of Windows local accounts by default. If you need to bypass the logon time restrictions on Active Directory user accounts, click on Reset Active Directory Password option and the program will list your domain user accounts on your domain controller.

Choose a local account or domain user account, then click on Reset Password button. This program will reset your password and remove the logon time limits that was set on your select account. Because domain user account doesn’t accept blank password, the program will assign a new password (Password123) to your AD account.

Remove the CD and reboot the machine. You can then log on your computer with your local account or domain user account without time restrictions. Well, that is how you bypass the account logon time restrictions on Windows user account. Hope it helps you in some way.
