How to list Explorer extensions and disable them?

Use  Autoruns from Sysinternals (Microsoft).

This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and when you start various built-in Windows applications like Internet Explorer, Explorer and media players. These programs and drivers include ones in your startup folder, Run, RunOnce, and other Registry keys. Autoruns reports Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond other autostart utilities.

Autoruns‘ Hide Signed Microsoft Entries option helps you to zoom in on third-party auto-starting images that have been added to your system and it has support for looking at the auto-starting images configured for other accounts configured on a system. Also included in the download package is a command-line equivalent that can output in CSV format, Autorunsc.

You’ll probably be surprised at how many executables are launched automatically!




Simply run Autoruns and it shows you the currently configured auto-start applications as well as the full list of Registry and file system locations available for auto-start configuration. Autostart locations displayed by Autoruns include logon entries, Explorer add-ons, Internet Explorer add-ons including Browser Helper Objects (BHOs), Appinit DLLs, image hijacks, boot execute images, Winlogon notification DLLs, Windows Services and Winsock Layered Service Providers, media codecs, and more. Switch tabs to view autostarts from different categories.

To view the properties of an executable configured to run automatically, select it and use the Properties menu item or toolbar button. If Process Explorer is running and there is an active process executing the selected executable then the Process Explorer menu item in the Entry menu will open the process properties dialog box for the process executing the selected image

Navigate to the Registry or file system location displayed or the configuration of an auto-start item by selecting the item and using the Jump to Entry menu item or toolbar button, and navigate to the location of an autostart image.

To disable an auto-start entry uncheck its check box. To delete an auto-start configuration entry use the Delete menu item or toolbar button.

The Options menu includes several display filtering options, such as only showing non-Windows entries, as well as access to a scan options dialog from where you can enable signature verification and Virus Total hash and file submission.

How to Register Windows Shell Extension

You can register a shell extension with the help of the regsvr32.exe command-line utility included in the Windows operating system. To do it, you should run it with the full path to your dll file specified as a parameter:

Start command-line utility
Register shell extension


To unregister your extension, you should run the same utility and specify not only the path but also the /u option:


Unregister shell extension

64-bit systems have both the 64-bit version and the 32-bit version of regsvr32 included in them. Moreover, if you pass your 32-bit extension to the 64-bit version of regsvr32, regsvr32 will automatically run the 32-bit version of regsvr32 and pass the name of the extension to it. The opposite is true as well. It allows any version of Regsvr32 to correctly register both 32- and 64-bit extensions.

Administrator privileges are required to register a shell extension. So you have to register it using an account that has the corresponding privileges on Windows XP and earlier. Starting from Windows Vista, it is possible to request administrator privileges. So if you do not have administrator privileges on these systems, it is recommended to run the regsvr32.exe utility from the command-line prompt launched with the “Run as administrator” command:

Start command-line utility

The Shell Ace library includes the RegExtension shell extension. If you choose to install this extension during the installation of Shell Ace, you can use RegExtension to register/unregister your extensions. When RegExtension is registered in the system, it adds the Register and Unregister items to the context menu opened with a right click on a dll file. Selecting one of these items will start the procedure of either registering or unregistering the dll file:


If the current user has no administrator privileges, the extension will request them by showing the corresponding dialog box where you should confirm granting administrator privileges.

The RegExtension extension also adds additional buttons to the Explorer toolbar (only in Windows XP and Windows 7):


These additional buttons work similarly to the corresponding items on the context menu.

When you distribute your extensions, it is recommended to register them with the regsvr32 utility because it calls the functions of the Shell Ace library in the end. It is recommended to do it because hidden keys can be added together with the actual registration of the COM object during the registration of extensions.

Thus, for instance, the DisableLowProcessIsolation key can be written when you register your Preview handler extension depending on the data load methods you use in the extension. By default, Explorer tries to pass a file stream to the Preview handler and, if it fails, stops working with the extension and if you read data from a file instead of a stream in your extension, your extension will not work in this situation. The DisableLowProcessIsolation key is used to solve this problem. It makes Explorer pass a file name instead of a stream to the extension.

Similar hidden keys considerably affect the performance of extensions and if you register your extension with the help of the regsvr32 utility, you do not have to keep in mind a lot of small details and can focus on the important thing – the functionality of your extension.

Renaming a network folder in Windows 7 Explorer fails with “the action can’t be completed…”

To work around the issue, enable User Group Policy setting for “Turn off the caching of thumbnails in hidden thumbs.db files”:
Policy Path User Configuration\Administrative Templates\Windows Components\Windows Explorer
Policy Setting “Turn off the caching of thumbnails in hidden thumbs.db files”
Policy Value Enabled
You can directly edit the registry with the following setting:
Registry path HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer
Setting Name “DisableThumbsDBOnNetworkFolders”
Value 1

Another workaround is to wait approximately 1-5 minutes then retry the rename operation.


Windows 7 client problem renaming & deleting folders on network drive

We have replaced a few older computers with new Windows 7 systems. We have one Win7 user that is having a problem when trying to rename folders that she creates on a network drive. The network drive is pointing to a Windows 2003 server that is up to date. She has all permissions but Full Control to the area she is working in. Problem: When she creates a folder, copies a file into it, then tries to rename the folder it gives her an error message stating the file/folder is in use and won’t let her rename it. If she waits for 5-10 minutes it will then let her rename it successfully. She can replicate the error. Then after a while the problem will go away completely and then hours or days later it will come back again. Very strange. She doesn’t seem to have any problems when working on her local c: drive. Please help. thanks

I have figured out why my Windows 7 users are having trouble renaming folders and files. The problem is the “caching of Windows 7 Thumbnails in hidden Thumbs.db files.” I won’t go into all the details but Windows 7 caches thumbnails by default and it keeps thumbs.db open for a while after a folder is created and files are copied into it. So basically if you disable this option in the Local Group Policy Editor you will no longer have this problem. Follow this link and you may need to reboot your computer. The referenced article is not specifically about renaming folders but details how to disable the caching.

The Add/Remove Programs is missing

Programs can be installed and uninstalled from the control panel on Windows operating systems. If the add and remove program icon is missing in the control panel,it will not be possible to use this feature. Without add or remove programs,it becomes difficult to uninstall programs in a clean manner. It is simple to fix this problem. Theadd and remove program icon can be missing in the control panel because of a damaged or missing applet required for this feature. The applet is present in the form of a command in the Windows system folders and it needs to be run once to solve the issue.
This can be due to a missing or damaged file – Appwiz.cpl

This applet is stored under the name appwiz.cpl in the system 32 folder.

  • First, open the Start menu and click Run.
  • Then, in the open window, type: appwiz.cpl

How to change associate file types with specific programs?

If you choose the wrong program in the dialog box “Open With” and set “Always use the selected program to open these files.” And if the program is removed properly, leaving the system in association with the file types it supports. There are several ways to fix it.
Method 1: Try to associate the files you want with the right programs using all the same dialog “Open with”
Method 2: Control Panel \ All Control Panel Items \ Default Programs \ Ask comparing “Change Program”
Method 3: Search in the registry branch [HKEY_CLASSES_ROOT]
Method 4: Use a utility Unassociate File Types, which allows you to remove both the association and remove the file type from the registry.

Place saving updates obtained through the Windows Update

After installing the update, you can save them on your computer by simply copying the folder the file you want. Files containing in its name -express, can not re-install. Therefore, you should not copy them.

How to check Windows software for malware, viruses or adware

Malware, short for malicious (or malevolent) software, is software used or programmed by attackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of code, scripts, active content, and other software. ‘Malware’ is a general term used to refer to a variety of forms of hostile or intrusive software.

Malware includes computer viruses, ransomware, worms, trojan horses, rootkits, keyloggers, dialers, spyware, adware, malicious BHOs, rogue security software and other malicious programs; the majority of active malware threats are usually worms or trojans rather than viruses.

There are lot of online tools for check software for malware:

  1. Virus Total - is a free service that analyzes suspicious files and URLs and facilitates the quick detection of viruses, worms, trojans, and all kinds of malware.
  2. Dr.Web Virusscan – service from Dr. Web.
  3. is a FREE on-line scan service, which checks uploaded files for malware, using antivirus engines, indicated in the VirSCAN list. On uploading files you want to be checked, you can see the result of scanning and how dangerous and harmful/harmless for your computer those files are.

All our software pass ALL tests without any problems!

Opening the Add/Remove Programs dialog takes too much time

Some users notice that opening the Add/Remove programs window takes a lot of time. The window itself opens, but it’s building the list that takes so long.

It can take long for following reasons:
1. You have really a lot of installed software
2. Your hardware is slow(especially HDD)
3. If the program doesn’t provide this information itself, Add/Remove Programs is forced to guess – with 1 and 2 it can takes really a lot of time.A program can add some properties to its registration to avoid a lot of this guessing. So please ask software developers to do it :-)
