Solution to System File Failure

Author: light rain (original)

Preface

When using Windows, some folders and applications in the system cannot be opened due to faults or viruses, these are all necessary for the use of computers.
 
We are troubled by these faults. How can we solve these faults? In the following article, we will introduce some common troubleshooting techniques for "cannot be opened" in Windows.

Cannot open "my computer", "My documents", etc.

Solution: it may be that the Explorer program has an error. The following method can be used to solve the problem.

1. Open notepad, add the following content to notepad, and save it as AAA. bat file, open it, and click OK in sequence (if not, try the second method );

Regsvr32 appwiz. cpl
Regsvr32 mshtml. dll
Regsvr32 jscript. dll
Regsvr32 msi. dll
Regsvr32 "C: Program FilesCommon FilesSystemOle DBOledb32.dll"
Regsvr32 "C: Program FilesCommon FilesSystemAdoMsado15.dll"
Regsvr32 mshtmled. dll
Regsvr32/I shdocvw. dll
Regsvr32/I shell32.dll

2. If the above cannot be repaired, copy the following content to notepad, save it as the yezi. reg file, and open it;

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOTexefileshellOpencommand]
@ = "" % 1 "% *"

Folder cannot be opened

Solution:

1. the folder cannot be opened in the resource browser or on my computer. Double-click the folder instead of opening it, and enter the search interface. You can modify the Registry to restore it. Go to the HKEY_CLASSES_ROOTDirectoryshell of the Registry and delete find. Another method is to click "new" in the "advanced" option of "folder", enter "OpenNew" in "operations ", enter "Explorer % 1" in "Application for executing operations. If you delete find, you do not need to configure it. If you create OpenNew, set "Opennew" to default.

2. In "my computer", the "Search" dialog box appears no matter which folder is opened, however, right-click the folder and select "open" To Go To The Running Control Panel. Double-click "Folder Options" and click the "file type" tab, find the "folder" in the "registered file type" list and select it. Click "advanced". In the "edit file type" dialog box that appears, if there is only one "find" option, click "new" under "operation" and enter "Open" under the "New Operation" dialog box ", enter "C: WindowsExplorer.exe" under "Application for operation", click "OK", select "Open", and click "set as default; if "Open" already exists, select it and set it to the default value.

What should I do if the EFS encrypted folder cannot be opened?

Solution:

EFS (Encrypting File System, encrypted File System) is a core File encryption technology based on NTFS File System proposed from Windows 2000, mainly used to protect local data. While using EFS to encrypt files, it also creates a lot of trouble, such as reinstalling the system and failing to open EFS encrypted folders, etc. How should we decrypt it? Now let's take a look at your discussion.

Backup and import key for decryption

To prevent the encrypted folder from being opened after the system is reinstalled, we can back up and import the key using the following method: click "Start> Run" and enter "certmgr. msc ", press enter to open the Certificate Manager. Expand Certificate/individual/certificate, right-click the certificate with the username in the right window, and select export in all tasks to open the certificate export wizard. Click "Next", select "Yes, export private key", click "Next", select the default export file format, and then click "Next", enter the password protection and confirm the password, click "Next", specify the file name, and click "finish.

After the system is reinstalled, right-click the exported private key file and select "Install PFX" to import the private key step by step. After the import is complete, you can smoothly open the EFS encrypted folder.

Unreliable software Approach

Without a backup key, it is almost impossible to decrypt EFS. Although many methods are popular on the Internet, the feasibility is minimal and we recommend you give up. Because some EFS uses a Public Key Certificate to encrypt files, and in Windows 2000/XP, each user uses a unique SID (Security Flag ). When the folder is encrypted for the first time, the system generates the user's key based on the encrypted SID and saves the public key and key separately. If the current key is not backed up before the system is reinstalled, it means that no previous user key can be generated in any case. decryption of a file requires both the public key and the password, therefore, you cannot open folders encrypted by EFS.

Unable to open "Add/delete program"

The reason why the "Add/delete program" cannot be opened may be that the dynamic link library file registration is invalid. You only need to register these files again.

Solution: In "Start> Run", enter the following commands and confirm them in the pop-up window.

Regsvr32 Appwiz. cpl
Regsvr32 Jscript. dll
Regsvr32 Mshtml. dll
Regsvr32 Msi. dll
Regsvr32 Mshtmled. dll
Regsvr32 "c: Program FilesCommon FilesSystemAdoMsado15.dll"
Regsvr32 "c: Program FilesCommon FilesSystemOle DBOledb32.dll"

Disk D cannot be opened

I often encounter Windows XP operating systems. I can't open a drive d by double-clicking it. right-clicking it to check that the original item was "automatic playback", so I had to right-click it to open it, double-click drive C and drive E.
 
Solution: Autorun. if there is a problem with the inf file, remove the attribute and delete it, and then search for autorun. find the file to which inf points and delete the shell Sub-item to open drive D.

Unable to open shortcuts

After I double-click the shortcut, there is always no response. What can I do?

In fact, shortcuts belong to a certain file type like normal files. If the program connected by the shortcut (*. lnk) is lost or incorrect, such files cannot be opened. The solution is as follows:

1. Windows 2000 and Windows XP:

Run "assoc. lnk = lnkfile" and restart.

2. Windows 98:

Download lnkfile. reg. Double-click it and click OK to add the complete registry data to the registry of the current system.

Unable to open LAN

In this case, there may be two main categories:

(1) the network connection is normal, and what we see is the real-time network status;

(2) What we see is just an illusion that the network connection is actually disconnected.

Solution: in the previous case, we will introduce the identity and access permissions of the users who access the resources shared by the Local Machine by the neighboring users on the Internet. Generally, when we access other computer resources through our network neighbors, we use the "guest (guest)" account. This is what most readers do not know, because in actual access, this is not reflected at all. This guest user does not need to enter any password for access, and the user name is not required. It is default by the system (that is, guest ). For this reason, if you can see the shared resources and the network connection is normal, it is likely that the guest account on the local machine is unavailable. Open the user account management program of the corresponding system to check whether the "guest" account is opened normally. If there is a red * on the small icon in front of the "guest" account *, this indicates that the "guest" account is currently disabled. Right-click to open it.

If the network connection is not normal, but the shared resources on other computers are displayed on the network neighbors, it will involve the cache of the main browser introduced in the overview of Browser service principles, it is also possible that the browsing list backup of the main browser is retained on the switch. Although the network connection is abnormal, the previous browsing list is still stored in the cache, so we still see the previous shared resources. This mainly occurs when the system exits abnormally, such as abnormal shutdown or crashes. The solution is to re-check the network connection and configuration. See the previous fault description.

The registry cannot be opened.

Solution: The registry is the hub and heart of the Window system. It records the vast majority of settings in the operating system. In the Window system, a registry editing tool is provided, which allows you to conveniently access and modify the Registry. This is Regedit.

However, after a malicious program on the Internet uses the Registry to modify the IE homepage, it not only modifies the registry, but also prevents you from using the registry for modification, when you execute this command, the system will pop up a dialog box: "registry editing has been disabled by the Administrator." The Registry tool is locked.

The following two methods can be used to solve the problem:

I. use scripts to solve this problem

Follow these steps to unlock the instance:
 
1. Click the "Start" menu, find the "Notepad" command from "program"> "attachment", and execute it.

2. Enter the following content in the notepad window: REGEDIT4 [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem]
"DisableRegistryTools" = dword: 00000000

3. Select the "save" command from the "file" menu and save the disk with the name "C: eg. reg,

4. Open "Resource Manager" and switch to drive C. Double-click the "reg. reg" file,

5. "Are you sure you want to add the information in C: eg. reg to the registry ?" Click "yes" in the dialog box ".

Then, the dialog box "Information in C: eg. reg has been successfully entered into the registry ." Indicates that the import is successful.

Click "OK" to close the dialog box.

2. Use group policies to solve the problem

In Windows 2000/XP/2003, click Start> Run, enter Gpedit. msc, and press enter to open group policy ". Expand "user configuration> management template> System", double-click "Disable registry editing tools" in the right window, and select "disabled" in the displayed window ", "OK" and then exit the "Group Policy" to unlock the registry.

The Registry is successfully unlocked!

Favorites cannot be opened

Solution: some malicious websites modify their favorites, mostly by modifying the "Desktop. ini" file in "C: WindowsFavorites", so you only need to delete the file. If the "C: WindowsFavorites" folder cannot be opened at all, delete it under DOS (you must use "attrib-r-s-h" before deleting it ). In addition, the content in "Favorites" is not deleted, but is put into another folder with the same name as "Favorites" (for example, "Favorites2"
