How to Manually Clear or Set Dirty Bit on Windows Volume

September 17th, 2016 by Admin

When a dirty bit is set on a volume, Windows automatically performs a disk checking the next time the computer is restarted. You can run the chkntfs command at the Command Prompt to check if a volume is dirty, but there is no way to clear the dirty bit unless you let Windows go through disk scanning at boot.

In this tutorial we’ll show you how to manually clear or set the dirty bit for a NTFS & FAT32 volume in Windows 10, 8, 7, Vista and XP. The procedure requires you to use a disk editor software such as WinHex. If you want to edit the dirty bit for a system volume currently in use, you need to use a WinPE bootable CD to boot off your PC.

How to Manually Clear or Set Dirty Bit on Windows Volume?

To get started, open WinHex as administrator rights. Click the Tools menu and select Open Disk.

When prompted to select a drive for editing, choose the logical volume you want to edit the dirty bit on, and then click OK.

For FAT32 Volume:

Click on “Boot sector” at the directory browser. The dirty bit for FAT32 volume is located at offset 0x41. If this volume is dirty, the bit should be 01. Just change 01 to 00 and then save your changes back to disk, now you’ve successfully cleared the dirty bit.

For NTFS Volume:

Click on $Volume at the directory browser. The offset location of the dirty bit is slightly different on every NTFS volume. To locate the dirty bit, look for a hex string of 13 bytes, beginning with 03 01, ending with 80 00 00 00 18. You should be able to find a match within the first or second sector.

The dirty bit is the 3th byte of the hex string that I’ve circled with red line. To set a dirty flag on the drive, just change it to 01. Or change it to 00 if you want to clear the dirty flag.

When it’s done, commit the change to the disk.

3 Ways to Run Disk Error Check in Windows 10, 8 and 7

September 17th, 2016 by Admin

All versions of Windows come with a useful disk checking feature which can check the integrity of your hard disk, fix file system errors and scan for bad sectors. In this tutorial we’ll show you 3 ways to run disk error check in Windows 10, 8 and 7.

Method 1: Run Disk Check from Windows Explorer

Open Windows Explorer. Right-click on the drive you want to run the disk check on, and choose Properties.
Select the Tools tab. Under the “Error checking” section, click on the Check button.
Click on Scan drive button to run the disk check.

If your selected drive is a system partition that is being used, Windows will let you schedule a disk check on the next restart.

Method 2: Run Disk Check Using the Chkdsk Command Line

Open an elevated Command Prompt.
- In Windows 10/8, simply press the Windows key + X and select “Command Prompt (Admin)“.
- In Windows 7, click on Start, navigate to Accessories, right-click on Command Prompt and select Run as administrator.
You can run the chkdsk command to run the disk check. Replace C: with the letter of the drive you’d like to run a disk check.
chkdsk /f /r C:

The /f flag tells windows to fix any issues and the /r flag tells it to do a deep scan. It locates bad sectors and recovers whatever information is readable.

Method 3: Run Disk Check By Setting The Dirty Bit

Sometimes if your PC is not properly shut down or crashed, a dirty flag is set on the disk to force disk check to be run at the next reboot. Here is a simple way to set a dirty bit for your drive manually:

Open an elevated Command Prompt.
Type the following command and press Enter. Replace C: with the letter of the drive you want to set as dirty.
fsutil.exe dirty set C:
Reboot your computer and Windows will force a disk check on your specified drive.

3 Ways to Reset Windows 10 Computer to Factory Settings

September 13th, 2016 by Admin

If your computer becomes sluggish, or freezes or hangs randomly, you might consider doing a factory reset. This will bring your Windows 10 laptop or desktop to the state when it was first turned on. In this tutorial we’ll show you 3 ways to reset Windows 10 computer to its factory default state, even if your computer is locked out or unbootable.

factory-reset-windows-10-pc

Method 1: Reset Windows 10 PC to Factory Settings After Logging in

After logging in to Windows 10, you can reset your computer to factory default settings using the Settings app. Follow these steps:

To open the Settings app, you can click the Start button and then click Settings, or press Windows key + I keyboard shortcut.
Click on Update & Recovery.
Select Recovery in the left-hand menu. Under Reset this PC, click on Get Started.
A new window will appear with two options: Keep my files or Remove everything. The former option will keep your personal documents, photos and music files intact. But both options will remove all your apps, programs and settings.
if you chose “Remove everything” in the prior step, you now have the option to “Just remove my files” or “Remove files and clean the drive.” In most cases, select “Just remove my files”. If the computer is going to be recycled or given to someone else, select “Remove files and clean the drive”.
Click on Reset. Your PC will reboot automatically and begin the factory reset process. This might take an hour or more.

Method 2: Reset Windows 10 PC to Factory Settings from The Login Screen

If you forgot Windows 10 password and couldn’t log on to your computer, you can also perform a factory reset from the login screen. Here’s how:

When you’re on the login screen, hold down the SHIFT key, click the Power button in the lower-right corner and select Restart.
The computer will reboot and take you to the Choose an option screen. Click on Troubleshoot.
On the next screen, click on Reset this PC.
You’ll be presented with two options: Keep my files or Remove everything. If you’re not concerned about your personal files, click on the latter option.
If you choose to remove everything, you’ll also see a new option asking if you want to clean the drive, which means it will not only delete everything, but will try to securely erase everything so that data cannot be recovered.
Click on Reset button to start restoring Windows 10 to factory settings.

Method 3: Reset Windows 10 PC to Factory Settings Using Install Disc

When your computer becomes crashed or unbootable, then you’re unable to perform a factory reset using the above methods. In this case, you need to use your Windows 10 installation DVD to access the Factory Reset option.

Boot your computer with Windows 10 installation DVD. You may have to change the boot sequence in your BIOS if booting from a CD/DVD is not enabled.
On the Windows Setup screen, select your keyboard layout and language, and then click on Next.
On the next screen, click “Repair your computer“. Do NOT click “Install now“.
When the Choose an option screen appears, click on Troubleshoot.
Click on Reset this PC.
Click either “Keep my files” or “Remove everything,” depending on whether you want to keep your personal files untouched.
You’ll then be prompted to choose the target operating system.
If you want to restore only the drive on which Windows 10 is installed, you should click on “Only the drive where Windows is installed“. If you want to factory reset all the drives on your Windows 10 computer, you should click on “All drives“.
Now you’ll be presented with two options: Just remove my files and Fully clean the drive. If you choose “Fully clean the drive”, it will erase your files and data thoroughly.
Click Reset and the factory reset process will begin.

“I am unable to login with any account even local administrator, while login it shows ‘The sign-in method you are trying to use isn’t allowed. For more info, contact your network administrator‘. Please help me out on this problem.”

sign-in-method-not-allowed

If your account is not granted the permission to log on locally, you’ll get such an error message at login. To fix this problem, we need to tweak the local security policy, or domain controller policy if you’re facing the same login issue with a domain user.

For Standardalone Computer:

Press the Windows key + R and type secpol.msc in the Run box. Press Enter to open the Local Security Policy window.
Expand to Security Settings > Local Policies > User Rights Assignment. In the right pane, locate the policy named Deny log on locally. Double-click on it to modify.
Check if your problematic user account or the user groups it belongs to is listed there. If it is there, select it and click on Remove.
When it’s done, click Apply and then OK. Reboot your computer and you should be allowed to log on to your account locally.

For Domain Controller:

There is also a corresponding security policy existing in domain controller that can cause the problem “The sign-in method you are trying to use isn’t allowed. For more info”. Follow these steps to fix it:

To get started, open the Group Policy Management. In Windows Server 2008, you can click Start, then select All Programs > Administrative Tools > Group Policy Management.
On the left hand side of Group Policy Management, expand Forest > Domains > your domain name, and then click Group Policy Objects. In the right-hand window, double-click on Default Domain Controllers Policy and select Edit.
This will open the Group Policy Management Editor window. Navigate to:
Computer Configuration > Policies > Windows Settings > Security Settings > Local Policies > User Rights Assignments

In the right pane, double-click on Deny log on locally.
Check if your problematic domain account or the domain groups it belongs to is listed there. If it is there, select it and click on Remove.
Click Apply and OK to save your changes. Reboot your computer and you can then login without permission issues.

How to Change Lock Screen Timeout in Windows 10 / 8

September 8th, 2016 by Admin

The lock screen appears as a background image that is displayed when a user locks the PC. You need to tap any key or click the lock screen before you reach the login prompt.

windows-10-lock-screen

By default, the lock screen will automatically turn off the display after one minute of idle time. You might want to increase the idle time to make the lock screen stay longer, or set your PC to never turn off monitor. In this tutorial we’ll show you how to change the lock screen timeout in Windows 10 / 8.

Part 1: Add Lock Screen Timeout Setting to Power Options

To add the lock screen timeout setting to Power Options, you need to change the registry setting. Follow these steps:

Press the Windows key + R to open the Run box. Type regedit and hit Enter.
After the Registry Editor opens, navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7
In the right-hand pane, double-click the Attributes entry and change its value from 1 to 2 (Or set it back to 1 if you want to hide the lock screen timeout settings later).
Immediately after editing the registry, you will see a new option (Console lock display off timeout) to adjust in the advanced power settings for your power plan.

If you want to quickly make the registry changes without opening Registry Editor, simply open Notepad and copy / paste the following lines, save as any name with .reg extension.

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7] "Attributes"=dword:00000002

Then right-click on the .reg file and select “Open with” -> “Registry Editor” from the context menu. This will import your registry settings immediately.

Part 2: Change Lock Screen Timeout in Power Options

Open Control Panel in large or small icons view. Click on Power Options.
From the settings on the left-hand side, select Choose when to turn off the display.
Click Change advanced power settings.
Now, scroll down to Display, and expand it. You’ll see the new setting “Console lock display off timeout” that is only available after we’ve made the registry change above. As you can see, the lock screen timeout is set to 1 minute by default.
You can adjust the timeout for however many minutes you want, or set it to 0 so the lock screen will never time out and turn off the monitor.

Click Apply and then OK. Now you’ve successfully changed the lock screen timeout settings in Windows 10/8.
