Take Ownership of Registry Key & Assign Permissions Using Command-line

Last Updated on: November 24, 2020 by Ramesh

We’ve seen how to use the Registry Editor (regedit.exe) to change ownership of a registry key and subkeys. This article tells you how to change registry key ownership and grant permissions using the command-line.

Windows has the takeown.exe and icacls.exe console utilities to change file/folder ownership and permissions, but there are no such built-in tools for changing the registry key ownership using command-line. You’ll need a third-party tool named SetACL for the task.

How to Run a Program as SYSTEM (LocalSystem) Account in Windows

Last Updated on: May 18, 2021 by Ramesh

Many Windows system files, registry keys, and services are owned by the SYSTEM (a.k.a LocalSystem) account, which has a high privilege level. If you need to modify a registry key owned by the SYSTEM account, there are at least two options.

The first option that comes to your mind is to take ownership of the corresponding registry key, assign yourself Full Control permissions. Once the registry key or the values are updated, revert the permissions and ownership to SYSTEM.

There is, however, an easier option. You can run the program — e.g., the Command Prompt or the Registry Editor under the SYSTEM account directly and update the registry values.

This article lists 7 different methods using which you can run programs under the SYSTEM or LocalSystem account in any version of Windows, including Windows 10. You can also add a Run as SYSTEM right-click menu option for .exe files.

How to Batch Convert Word Documents into PDF Files

Last Updated on: April 18, 2025 by Ramesh

Microsoft Word is a top-notch word processor using which you can save documents in .doc, .docx, and different other formats. When you need to send a document to someone who doesn’t have Office Word installed, you usually convert the document to PDF and send it.

As you may have known, Microsoft Word lets you convert or save a document (.doc or .docx file) as a PDF file using the Save As dialog.

Open the document, and launch the Save as dialog. Select PDF (*.pdf) from the list and save the file.

Another option would be to use the Microsoft Print to PDF driver in Windows 10 to output the .doc or .docx file to a .pdf document. For this, you’d use the Print option (instead of Save as) to print the document to PDF.

Pre-Windows 10 systems don’t have the Microsoft Print to PDF driver. In those systems. you can use the free CutePDF Writer or Foxit PDF Printer (part of Foxit PDF Reader software.)

But, if you have tens or hundreds of Word documents that you want to convert to PDF, using the GUI option would be a time-consuming and tiring task.

This article tells you how to batch convert multiple .doc or .docx files to PDF files using Windows Script and other methods.

Fix: Can’t delete Avast Software Registry Key in Windows

Last Updated on: August 2, 2023 by Ramesh

Last week when I installed CCleaner on my system, it also installed Avast antivirus software stealthily, in the background. After I uninstalled Avast, a registry key named AVAST Software still remained in the registry, but it couldn’t be opened. When the AVAST Software branch was selected, it threw the following error:

Error Opening Key
AVAST Software cannot be opened.
An error is preventing this key from being opened.
Details: The system cannot find the file specified.

When I opened the Properties of the AVAST Software key, the Security tab was blank, showing the message: The requested security information is either unavailable or can’t be displayed.

I tried running Sysinternals RegDelNull to nuke the keys, but that didn’t help.

The same error can occur for AVG antivirus users.

Error Opening Key
AVG cannot be opened.
An error is preventing this key from being opened.
Details: The system cannot find the file specified.

Registry Reparse Point

Later I realized that the HKEY_LOCAL_MACHINE\Software\AVAST Software is a reparse point or registry link that links to the following key on Windows 64-bit systems:

HKEY_LOCAL_MACHINE\Software\WOW6432Node\AVAST Software

But, since the Avast uninstaller had wiped out the above key, the reparse point still remains but is orphaned.

On Windows 32-bit systems, the reparse point and the target key paths are reversed.

However, once I knew it’s only a reparse point, the fix turned out to be very simple; you don’t need to tinker with the registry key permissions or ownership.Read more
