How to Stop Internet Explorer from Opening dowloaded Zip Files

When you download a file, such as a Zip file, using Internet Explorer, the File Download dialog will open and allow you to choose whether you want to Open or Save the file. This dialog typically includes a check box labeled Always ask before opening this type of file which is checked by default. This insures that the dialog will continue to display at other times when you download the same type of file.   However, if you uncheck this box and choose to Open the file being downloaded (see the picture below), the next time you attempt to download another file of this type you will not have the opportunity to choose whether to open or save the file. The File Download dialog will no longer appear.

Please see the steps below if you want Internet Explorer to display the File Download dialog for this file type again. Please see the steps below if you want Internet Explorer to display the File Download dialog for this file type again. Note: The latest versions of Internet Explorer on Windows 8 and Windows 7 do not offer an "Always ask..." checkbox. This issue should not occur in such cases. Windows 7 / Windows Vista Unlike earlier versions of Windows, there is no option offered in a user interface for resetting or changing this behavior. The only way, of which we are aware, for setting this back to the default without resetting all Internet Explorer zones is by editing the Windows Registry. To begin, do this: From the taskbar, click on the Start button In the field directly above Start type: regedit Press the Enter key on the keyboard Browse to: HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046} Note: {0002DF01-0000-0000-C000-000000000046} is the Class ID for the InternetExplorer.Application object. Inside this registry key, there will be a list of value data corresponding to all the file types for which you have unchecked the Always ask before opening this type of file box. For example, if WinZip automatically opens Zip files you download, you will see WinZip in the list. Deleting the WinZip entry from this list will reset the behavior for all files that would normally be opened by WinZip. Another option would be to do the following: Open Internet Options from the Control Panel Click the Security tab Click the Reset all zones to default level button Note: By doing this all custom changes you have made will be reset to the default Click OK Windows XP Open Windows Explorer or My Computer Choose Folder Options from the Tools Menu Click the File Types tab Scroll down the list of Registered file types to ZIP (or ZIPX), click this to select it, and click the Advanced button In the resulting Edit File Type dialog, check the box labeled Confirm open after download, and then click OK Click OK in Folder Options Now, when you download a Zip file (.zip or .zipx) using Internet Explorer, the File Download dialog will display again and will ask if you want to open the file or save it.

Files Types Tab not found in windows 7

There is no file types tab in Folder options in Windows 7?

Earlier Windows Versions (e.g., XP) allowed you to edit this via the Windows file system explorer menu Tools>Folder Options..... dialog, the File Types tab.  There you could define which program is associated with each file extension

Then you must be wondering as to why the ‘File Types’ tab is missing from the ‘ Folder Options’ dialog (accessible from Windows Explorer Organize menu). Well, Windows 7 no longer has the ‘File Types‘ tab in Folder Options. File Types has now become Default Programs of Start Menu. 

Want to change the default program with which a file is opened upon double click? For this you need to set an association between the file extension and a program used to open it. Here is how you can do this in Windows 7:

1. Click on ‘Default Programs’ of Start Menu. This can be found in the right pane.

2. The Default Programs item of Control Panel opens up. Click on Associate a file type or protocol with a program.


3. In the next screen, you can view all file extensions and their file types. In order to change the default program for a file extension, chose the extension and click Change program… This will open the Open with dialog. (Alternatively the ‘Open with’ dialog can also be accessed on most files by right clicking the file and selecting ‘Open with’ –> ‘Choose default program’)

4.The current default program along with other recommended programs is displayed in the top section. Click on the chevron(down arrow) of Other Programs.


5. Choose one from the available list or click on Browse and select a program to make it the default program for that file extension.

From now on Windows will always open the newly selected program whenever you double click or click Open on files of that extension.

Uninstall Hidden Devices Drivers and Services

This tutorial describes the steps used to remove unwanted devices, drivers, and services from the device manager. These instructions can be used with Windows 2000, XP, Server 2003, Vista and Windows 7.

Have you had drivers or devices that will not go away even though you are sure you have uninstalled them? Have you replaced your old 100Mbps network card with a faster Gbps adapter, but you cannot re-assign it the same IP address because your system insists there is still an adapter installed with that same IP address?

The system also insists that you forgot to remove the driver before removing the old card. Unwanted items in the device manager can cause numerous problems such as these. To get rid of unwanted drivers, devices, or services, use the following steps:

1) Open the Start menu and choose Run.
2) Type in cmd and click OK.
3) At the command prompt, type in set devmgr_show_nonpresent_devices=1 and press Enter. (Note          that nothing seems to happen. This is expected. You are actually setting an environment variable which is
     going to help you to see hidden devices.)
4) On the next command prompt line, type devmgmt.msc and press Enter. This will launch the Windows           Device Manager Console.
5) In the Device Manager Console, from the View menu, select Show Hidden Devices.

As you expand the different drivers and devices in the device manager, you will see not only the items that Windows currently detects as installed on your PC; but you will also see drivers, devices, and services which have been loaded in the past but were not uninstalled or are not currently started.

You can find your offending device, right-click, and choose uninstall to remove it from the system completely.

Note that non-loaded devices, drivers, and services are “grayed” out, but that does not necessarily mean that you should delete all of them. Only remove items you know you do not need.

Be careful that you do not change too many devices, or you might need to re-activate your Windows installation. Finally, if you accidentally exit the Device Manager Console you will need to start over again at the command prompt.

To close the command prompt window, type exit.

5 Ways to Re-enable Registry Editor When Disabled By Virus

We have already discussed how to re-enable task manager and other problems that can be solved by using the Windows Registry Editor. Now, users may experience a serious dilemma if the Registry Editor itself is disabled. This can be due to a Trojan, virus, spyware or a Malware infection to your system. Whenever this occurs, an attempt to start the editor results in the appearance of a  message declaring that “Registry editing has been disabled by the Administrator”.

This creates a setback to the solutions of various other problems using the Registry Editor. However, how much complicated this problem may seem, it’s certainly not incurable. In fact, we, in this article will discuss how simple it is to re-enable your Registry Editor. The fixes that we show here, work in Windows XP, Windows Vista and also in Windows 7.

Fix 1 : From the Run command

Click on the “Start” button and then select “Run”, or simply press “Windows Key+R”. The Run application starts and in the box copy and paste the following line :

REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System

 /v DisableRegistryTools /t REG_DWORD /d 0 /f

Click OK and then reboot your computer. On restart, the Windows Registry Editor is re-enabled.

Fix 2 : By removing the regedit.com file

Another simple solution to re-enable your Registry Editor is to rename the “regedit.com” to “regedit.exe”. Sometimes, some viruses or malware loads a “regedit.com” file in the system. This “.com” file is usually a zero byte dummy file which either replaces the actual “regedit.exe” file or is added as a new file.  Now, when you type “regedit” in the “Run” box, this “.com” file is executed rather than the actual “.exe” file, since “.com” files get a greater preference than “.exe” files in the process of execution of a program.

1. Open the drive where the Windows operating system is installed.
2. Then open the folder named “WINDOWS” in that drive.
3. Notice if the file “regedit” is a “.com” zero byte dummy file or not.
4. If it is so, then delete it permanently.

In case of invasion of a worm named “W32.Navidad”, the “regedit.exe” gets renamed to “regedit.com”. In such a case you just have to rename the “.com” file by “regedit.exe”. You will now be able to access the Registry Editor normally.

Fix 3 : By editing the Group Policy

At first go to Start > Run or simply press “Windows key+R”. Type “gpedit.msc” in the Run box and click OK.


The Group Policy Editor opens up. Navigate to User Configuration > Administrative Templates>System. Now, on the right hand part of the Group Policy Editor, in the “Setting” column, double click on “Prevent Acess to Registry Editing Tools”.



The Properties box appears and here, change the property to “Not Configured”. If it is already so, select “Enable” and apply it. Then repeat the Fix 3 process to change the setting to “Not Configured”. This removes the Disable Registry Tools value successfully. Click on Apply, then OK and exit the Group Policy Editor.


Reboot your system. On resuming from the restart, the Registry Editor is enabled once again.

Fix 4 : By VB script

A different way to solve this problem is by using a Visual Basic script. Depending upon its position in the registry, the script enables or disables the Registry Editor. Doug Knox, a Microsoft Professional, created such a VB script “reg_enable.vbs”. Download this VB Script. Save this on the Desktop in your system. Make sure to save this file with the extension “.vbs”.


Now follow the steps below :

1. Double click on the downloaded file to run it.
2. If you are prompted for an Administrative Password, enter it and press ENTER.
3. After this is done, restart your computer.

Your Registry Editor is re-enabled on completing reboot.
Instead of double clicking on the file, you may also open a Command Prompt window by clicking Start > All Programs > Accessories > Command Prompt.

1. Now, type cd /d %userprofile%\desktop . [Replace %userprofile% by the Windows profile name of the user].
2. Then type wscript.exe  reg_enable.vbs and press ENTER.
3. Type EXIT and press ENTER to close the Command Prompt window.

The Disable Registry Tools policy gets removed and your can access Registry Editor normally.

Fix 5 : By installing the UnHookExec.inf

Sometimes invasions by trojans, worms etc. edits the shell > open > command registry entries. Each execution process of an “.exe” file, executes the virus. In such a case,

1. Visit the Symantec website and download the “UnHookExec.inf” file.
2. Save this file on your desktop making sure that the file extension is “.inf”.
3. Right click on this file and choose to install.
4. With the process completed, restart your system.

Resuming Windows after reboot, restores the command registry entries and the Registry Editor is re-enabled.
Any of the above 5 fixes can be used to re-enable the Registry Editor. These fixes work in all versions of Windows.

To disable system restore you should follow these steps.

To activate System Restore, make sure there is NO tick in the box "Turn off System Restore on all drives".
WARNING: By disabling system restore you will delete all stored restore points.

To enable system restore you should follow these steps.

By default system restore is enabled on Windows XP machines, so there is a good chance that it is already enabled if this is your first time working with system restore.
You should first go into the Control Panel and then double click on the System icon. If you are in the control panel and do not see the System icon, then click on the link that says "Switch to classic view" in the upper left hand side of the window. Now you should be able to see the System icon. After you double click on it you should then click on the System Restore tab. If system restore is turned off you will see an image like Figure 2 below.


                   Figure 2. Enabling System Restore

               .  If you see in the Status section, designated by the green box, that it is Monitoring a partition, then system restore is already enabled and you do not have to do anything further. If it is showing that it is turned off as seen in Figure 2 above, then you should uncheck the checkbox labeled "Turn off System Restore", designated by the red box, and then adjust how much disk space you want to allow system restore to use, which is by default 12 percent of your entire disk space.
When you are done with making your settings, you should click on the apply button. Since you are turning system restore back on, a new restore point will automatically be made. After the new restore point is made, you should see in the status section that system restore is monitoring the partition; which means it is enabled.
Clicking the Settings button just brings up a box with a slider on it. This lets you adjust how much hard disk space to let Windows XP use for your Restore Points:

If there are any problems with your computer since you restored to this restore point, you can revert back to your previous settings by going back into the System Restore Utility and selecting the "Undo my last restoration" radio button and pressing the Next button as show in Figure 9 below.

Figure 9. Undo your last Restoration

Deleting Restore Points

There are three known safe ways to delete restore points stored on your computer. These ways are described below:

Disk Cleanup - Launch the Disk Cleanup tool and then select the more options tab. On this tab you will find a section for System Restore. If you press the Clean Up button for that section, Windows will delete all restore points except for the most recent one.

Turn off System Restore - Just by turning off System Restore all your restore points will be deleted. Unless you want this to happen, be careful that you don't mistakenly delete all your restore points by disabling system restore.

System Restore runs out of storage space - If system restore runs out of the storage space that has been allocated towards its use, it will delete the oldest restore point in order to create space for the new restore point.

Problems with System Restore
There are some problems associated with System Restore when it comes to viruses. When restore points are created they are stored in a directory that is accessible only to the System account and not to a user. This keeps the restore points safe from misuse and tampering. Unfortunately this also means that any virus scan software you may have installed can not scan the files located there as well. This causes a problem if a file that is infected with a virus gets backed up into a restore point because now the anti-virus software can not clean it. Now if you ever restore from a restore point, that file that is infected will be introduced back into your system.
With this in mind, if you find that you are infected with a virus, hijacker, or spyware and want to make sure you do not get reinfected if you restore a restore point, you should turn System Restore off and then back on again to clear all the restore points. This will guarantee that their are no infected files that could be restored.

Advanced Info

WARNING: Information found in this section is for advanced users only. If you use this information without advanced knowledge of your operating system you can cause serious damage to your Windows installation.

All restore points are stored in a folder that starts with _restore in the System Volume Information folder found in the root of your individual partitions. This folder is used to store copies of your registry, files, configs, etc. The system volume information folder is only accessible to the System account by default. You can access this folder, though, by adding yourself to the security permissions of this account. Though its advised that you do not do so, I am sure that some of you will poke around in there anyway. Remember, doing this is at your own risk.

Most of the configuration options for System Restore can be found at the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore
One interesting key you can change here is the interval Windows uses to make an automatic restore point. By changing the value, which is the total seconds between automatic restore point creation, you can make Windows create restore points more often or less frequent. The default value is 86400, which in seconds corresponds to 24 hours between each automatic restore point creation.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\RPGlobalInterval

For more information on the registry keys used by System Restore read this Microsoft Knowledgebase article:

The Registry Keys and Values for the System Restore Utility

You can also specify what registry keys should not be restored and what files should not be backed up by System Restore.

These registry keys are:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\KeysNotToRestore
The values contained in the FilesNotToBackup key are files or directories, in which you can specify wildcards as well to exclude all files in a particular directory. Any files listed in this way will not be added to a restore point when one is created.
The values contained in the KeysNotToRestore key are registry keys that should not be restored if you ever restore your computer to a previous restore point.

Windows Vista and 7 users

In the Start search box type System Restore and press enter.

Just like old version of Windows, recent ones are also having the tool System Restore. System Restore for Windows Vista or Windows 7 can overwrite damaged configuration, files and programs with an unspoiled version if you enabled System Restore forWindows Vista or 7. This procedure is only effective if a restore point is present on the computer. Thus, it is vital to have an organized restore points with descriptive changes and type of update performed on the computer.

To restore Windows Vista or Windows 7 to an earlier date please follow these guidelines:

- Log-on to Windows with Administrative rights.

- Click on Start.

 -In the search box, type System Restore and click System Restore on the results.

Alternatively, you may type rstrui.exe and press Enter on the keyboard.

When I run system restore I get a message saying no restore points are available

A computers System Restore points could be deleted by any of the below possibilities. Unfortunately when the system restore points are deleted or removed they cannot be recovered. 

1. The Microsoft Windows XP System Restore option was disabled on the computer.
2. The computers hard drive is out of disk space or low on disk space.
3. Microsoft Windows has been reinstalled.
4. The restore point reached is maximum age of 90-days.
5. The "Clean up" option under the Disk Cleanup has been ran. When this option is performed it will remove all restore points.
6. The computers version of Microsoft Windows has been upgraded to a newer version of Windows. The Windows System Restore option is not designed to revert your computer back to an older version of Windows and when an update is ran it will disable any previous system restores.
