How to Take Ownership (Permission) of Protected Registry Key in Windows 10

September 20th, 2016 by Admin

Sometimes you might encounter some registry keys that are protected by Windows. When you try to edit, rename or delete a protected registry key or value, you’ll get one of the following errors:

“Cannot edit {value_name}: Error writing the value’s new contents.”

“The Registry Editor cannot rename {key_name}. Error while renaming key.”

“Unable to delete all specified values.”

“Cannot delete {key_name}: Error while deleting key.”


Even you’re logged in as Administrator, you might still lack permissions to edit a protected registry key. In such cases, you need to take ownership of that particular key and grant full permissions to your signed-in account. This step-by-step tutorial will guide you how to take full ownership of protected registry key in Windows 10.

How to Take Full Ownership of Protected Registry Key?

  1. To start, press the Windows logo key + R on your physical keyboard, type regedit and press Enter to open the Windows Registry.


  2. Navigate to the protected key you want to take ownership of. For this example, we chose the following key:


  3. Right-click on the protected key, and select Permissions from the context menu that appears.


  4. In the Permissions window that appears, Click Advanced.


  5. In the Advanced Security Settings dialog, you can see the current owner (SYSTEM or “TrustedInstaller“) of your selected key. Click on Change button.


  6. This will open a new dialog box. Now type your user account name, and then click on “Check Names” button to convert the username to correct format. Click OK.


  7. Now you’ll see that your user account is showing up as the owner. Check the “Replace owner on subcontainers and objects” option if you also want to take ownership of the subkeys. Click OK.


  8. When back to the Permissions window, select the desired user name and then check Allow checkbox under the Full Control row, and click OK.


    If your user account is not shown under the Group and user names list, click on Add button.

  9. Close Registry Editor. Now you’ve taken ownership of a protected registry key and grant your account full permissions. That’s it!

How to Stop Check Disk (Chkdsk) From Running at Startup

September 18th, 2016 by Admin

There are some situations where your PC needs to run a check disk at startup or reboot. For instance, if you run the chkdsk command on a system drive that is being used to run the Windows OS, it will schedule a disk check to run at the next reboot. Windows might also force an automatic disk check when your computer shuts down unexpectedly.


Checking disk could be a really time-consuming task. If you don’t want Windows to take its time during the next reboot, here is how you can cancel or stop check disk (chkdsk) from running at Startup in Windows 10, 8, 7, Vista and XP.

Part 1: Check if a Manual/Automatic Disk Check is Scheduled

Open a Command Prompt as an administrator in Windows. Type in the following command and press Enter.
chkntfs C:

If there is a chkdsk task scheduled you will receive a response that is similar to “chkdsk has been scheduled manually to run on next reboot.


If a dirty flag is set on your drive, the system will force an automatic disk check at the next reboot.


Part 2: Stop Check Disk from Running at Startup

The methods of stopping check disk varies depend on how it is scheduled.

Option 1: Cancel the Automatic Disk Check

When the computer boots up with the dirty bit enabled on a drive, you will be asked to check the disk for consistency before Windows is loaded. But sometimes Windows might keep running check disk automatically on every reboot and this could be quite annoying. To stop the automatic disk check, you have to clear the dirty bit by following this tutorial: How to Manually Clear or Set Dirty Bit on Windows Volume

Option 2: Cancel the Scheduled Disk Check

It’s much easier to stop the scheduled disk check. You can cancel the scheduled disk check using either Command Prompt or Registry Editor.

Method 1: Using Command Prompt

Open a Command Prompt as an administrator. If you want to disable a scheduled disk check on C: drive, type the following command and press Enter.
chkntfs /x C:


Method 2: Using Registry Editor

Open the Registry Editor. Navigate to the following keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

Double-click on the Multi-String value “BootExecute” in the right pane.


This will open the “Edit Multi-String” window. Click in the Value data box, and then delete all of the lines, except the last one.


When it’s done, click OK and close Registry Editor.

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.
