loadTOCNode(2, 'resolution');

To reregister the Windows Installer, verify the location of the Msiexec.exe file on your hard disk and in the Windows Registry, and then reregister the Windows Installer. To do this, follow these steps. Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
Determine the location of the Msiexec.exe file on your hard disk. To do this, follow these steps:
Click Start, click Run, type %windir%\system32, and then click OK.Note This step will open the folder where the Msiexec.exe file is located.
Make a note of the location of the Msiexec.exe file. The location of the Msiexec.exe file will be a combination of the value in the Address text box and the Msiexec.exe file name itself. For example if the Address text box contains a value of C:\Windows\system32, the location of the Msiexec.exe file will be C:\Windows\system32\Msiexec.exe.

Manual steps to recover a corrupted registry that prevents Windows XP from starting

The procedure that this article describes uses Recovery Console and System Restore. This article also lists all the required steps in specific order to make sure that the process is fully completed. When you finish this procedure, the system returns to a state very close to the state before the problem occurred. If you have ever run NTBackup and completed a system state backup, you do not have to follow the procedures in parts two and three. You can go to part four.

Part one

In part one, you start the Recovery Console, create a temporary folder, back up the existing registry files to a new location, delete the registry files at their existing location, and then copy the registry files from the repair folder to the System32\Config folder. When you have finished this procedure, a registry is created that you can use to start Windows XP. This registry was created and saved during the initial setup of Windows XP. Therefore any changes and settings that occurred after the Setup program was finished are lost.

To complete part one, follow these steps:

1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
   Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
4. When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.
5. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:
   md tmp
   copy c:\windows\system32\config\system c:\windows\tmp\system.bak
   copy c:\windows\system32\config\software c:\windows\tmp\software.bak
   copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
   copy c:\windows\system32\config\security c:\windows\tmp\security.bak
   copy c:\windows\system32\config\default c:\windows\tmp\default.bak
   
   delete c:\windows\system32\config\system
   delete c:\windows\system32\config\software
   delete c:\windows\system32\config\sam
   delete c:\windows\system32\config\security
   delete c:\windows\system32\config\default
   
   copy c:\windows\repair\system c:\windows\system32\config\system
   copy c:\windows\repair\software c:\windows\system32\config\software
   copy c:\windows\repair\sam c:\windows\system32\config\sam
   copy c:\windows\repair\security c:\windows\system32\config\security
   copy c:\windows\repair\default c:\windows\system32\config\default
   
6. Type exit to quit Recovery Console. Your computer will restart.

Note This procedure assumes that Windows XP is installed to the C:\Windows folder. Make sure to change C:\Windows to the appropriate windows_folder if it is a different location.

If you have access to another computer, to save time, you can copy the text in step five, and then create a text file called "Regcopy1.txt" (for example). To use this file, run the following command when you start in Recovery Console:

batch regcopy1.txt

With the batch command in Recovery Console, you can process all the commands in a text file sequentially. When you use the batch command, you do not have to manually type as many commands.

Part two

To complete the procedure described in this section, you must be logged on as an administrator, or an administrative user (a user who has an account in the Administrators group). If you are using Windows XP Home Edition, you can log on as an administrative user. If you log on as an administrator, you must first start Windows XP Home Edition in Safe mode. To start the Windows XP Home Edition computer in Safe mode, follow these steps.

Note Print these instructions before you continue. You cannot view these instructions after you restart the computer in Safe Mode. If you use the NTFS file system, also print the instructions from Knowledge Base article KB309531. Step 7 contains a reference to the article.

1. Click Start, click Shut Down (or click Turn Off Computer), click Restart, and then click OK (or click Restart).
2. Press the F8 key.
   
   On a computer that is configured to start to multiple operating systems, you can press F8 when you see the Startup menu.
3. Use the arrow keys to select the appropriate Safe mode option, and then press ENTER.
4. If you have a dual-boot or multiple-boot system, use the arrow keys to select the installation that you want to access, and then press ENTER.

In part two, you copy the registry files from their backed up location by using System Restore. This folder is not available in Recovery Console and is generally not visible during typical usage. Before you start this procedure, you must change several settings to make the folder visible:

1. Start Windows Explorer.
2. On the Tools menu, click Folder options.
3. Click the View tab.
4. Under Hidden files and folders, click to select Show hidden files and folders, and then click to clear the Hide protected operating system files (Recommended) check box.
5. Click Yes when the dialog box that confirms that you want to display these files appears.
6. Double-click the drive where you installed Windows XP to display a list of the folders. If is important to click the correct drive.
7. Open the System Volume Information folder. This folder is unavailable and appears dimmed because it is set as a super-hidden folder.
   
   Note This folder contains one or more _restore {GUID} folders such as "_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".
   
   Note You may receive the following error message:
   C:\System Volume Information is not accessible. Access is denied.
   If you receive this message, see the following Microsoft Knowledge Base article to gain access to this folder and continue with the procedure:
   309531 (http://support.microsoft.com/kb/309531/ ) How to gain access to the System Volume Information folder
8. Open a folder that was not created at the current time. You may have to click Details on the View menu to see when these folders were created. There may be one or more folders starting with "RPx under this folder. These are restore points.
9. Open one of these folders to locate a Snapshot subfolder. The following path is an example of a folder path to the Snapshot folder:
   C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot
10. From the Snapshot folder, copy the following files to the C:\Windows\Tmp folder:
    • _REGISTRY_USER_.DEFAULT
    • _REGISTRY_MACHINE_SECURITY
    • _REGISTRY_MACHINE_SOFTWARE
    • _REGISTRY_MACHINE_SYSTEM
    • _REGISTRY_MACHINE_SAM
11. Rename the files in the C:\Windows\Tmp folder as follows:
    • Rename _REGISTRY_USER_.DEFAULT to DEFAULT
    • Rename _REGISTRY_MACHINE_SECURITY to SECURITY
    • Rename _REGISTRY_MACHINE_SOFTWARE to SOFTWARE
    • Rename _REGISTRY_MACHINE_SYSTEM to SYSTEM
    • Rename _REGISTRY_MACHINE_SAM to SAM

These files are the backed up registry files from System Restore. Because you used the registry file that the Setup program created, this registry does not know that these restore points exist and are available. A new folder is created with a new GUID under System Volume Information and a restore point is created that includes a copy of the registry files that were copied during part one. Therefore, it is important not to use the most current folder, especially if the time stamp on the folder is the same as the current time.

The current system configuration is not aware of the previous restore points. You must have a previous copy of the registry from a previous restore point to make the previous restore points available again.

The registry files that were copied to the Tmp folder in the C:\Windows folder are moved to make sure that the files are available under Recovery Console. You must use these files to replace the registry files currently in the C:\Windows\System32\Config folder. By default, Recovery Console has limited folder access and cannot copy files from the System Volume folder.

Note The procedure described in this section assumes that you are running your computer with the FAT32 file system. For more information about how to access the System Volume Information Folder with the NTFS file system, click the following article number to view the article in the Microsoft Knowledge Base:

309531 (http://support.microsoft.com/kb/309531/ ) How to gain access to the System Volume Information folder

Part Three

In part three, you delete the existing registry files, and then copy the System Restore Registry files to the C:\Windows\System32\Config folder:

1. Start Recovery Console.
2. At the command prompt, type the following lines, pressing ENTER after you type each line:
   del c:\windows\system32\config\sam
   
   del c:\windows\system32\config\security
   
   del c:\windows\system32\config\software
   
   del c:\windows\system32\config\default
   
   del c:\windows\system32\config\system
   
   copy c:\windows\tmp\software c:\windows\system32\config\software
   
   copy c:\windows\tmp\system c:\windows\system32\config\system
   
   copy c:\windows\tmp\sam c:\windows\system32\config\sam
   
   copy c:\windows\tmp\security c:\windows\system32\config\security
   
   copy c:\windows\tmp\default c:\windows\system32\config\default
   Note Some of these command lines may be wrapped for readability.
3. Type exit to quit Recovery Console. Your computer restarts.

Note This procedure assumes that Windows XP is installed to the C:\Windows folder. Make sure to change C:\Windows to the appropriate windows_folder if it is a different location.

If you have access to another computer, to save time, you can copy the text in step two, and then create a text file called "Regcopy2.txt" (for example). To use this file, run the following command when you start in Recovery Console:

batch regcopy2.txt

Part Four

1. Click Start, and then click All Programs.
2. Click Accessories, and then click System Tools.
3. Click System Restore, and then click Restore to a previous RestorePoint.

Access is Denied / Encryption

http://windowshelp.microsoft.com/Windows/en-us/help/31ad4562-aee7-4fed-8316-89114dc973031033.mspx

There are two things that you can try:

•

Check the permissions of the file or folder the file is saved in. Here's how: 1. Right-click the file or folder, and then click Properties. 2. Click the Security tab. 3. Under Group or user names, click your name to see the permissions you have. To open a file, you need to have read permission. For more information on permissions, see What are permissions?

•

Check to see if the file is encrypted. Here's how: 1. Right-click the file, and then click Properties. 2. Click the General tab, and then click Advanced. If the Encrypt contents to secure data check box is selected, you need the certificate that was used to encrypt the file to open it. You should get the certificate from the person who created the file. For more information, see Import or export certificates and private keys. Encrypting File System (EFS) is not fully supported on Windows Vista Starter, Windows Vista Home Basic, and Windows Vista Home Premium. For those editions of Windows, if you have the encryption key or certificate, you can do the following: • Open Command Prompt and decrypt files by typing Cipher.exe /d at the command prompt (advanced users). • Modify an encrypted file. • Copy an encrypted file as a decrypted file to a hard disk on your computer. • Import EFS certificates and keys. • Open Command Prompt and back up EFS certificates and keys by typing Cipher.exe /r at the command prompt (advanced users).

N82 Soft and Hard Reset

If you applied the settings you received, deleting the text message containing them isn't going to have any effect.

Note that all these operations but the first will wipe your phone's internal memory so do a backup before proceeding.

First option: revert to factory defaults . Dial *#7780#.

Second option: soft reset. Dial *#7370#.

Third option: hard reset. Switch the phone off and do the following.

1) Press and hold the green "call", "3" and "*" buttons.
2) With those buttons pressed down, switch the phone on.
3) Keep pressing those 3 buttons and only release them once the phone shows signs of life such as the Nokia "hands" logo or the language selection screen.

If you're prompted for a security code, the default on all Nokia phones is 12345 (unless you changed it, in which case you should know what it is).
