Registry failure causes and recovery and methods _ registration Form

The general symptom of a registry failure is when you load Win 95 o'clock, and the following message is displayed on the screen:

Registry File is not found. Registry services May is inoperative for this session. (registry file not found, this task registration is not valid). and give the restart for automatic recovery and ignore the two options. If you choose to recover automatically, the system automatically restores the state value of the system when it was last successfully started with the backup file after the reboot. However, if there are two consecutive times in this situation, the general is even the backup file is damaged, you need to do the following work.

There are three possible reasons for a registry failure: The System.dat file in the Win 95 directory does not exist, crashes, or is missing from the [Paths] portion of the Msdos.sys file.

If this is the first to second reason, you can use the following method for recovery:

1. Enter the win 95 directory to see if SYSTEM.DAT and USER.DAT files exist:

Attrib/system.dat

attrib User.dat

2. If SYSTEM.DAT, USER. DAT two file Graves  the Mirage, 4 steps, or skip to step 5th.

3. Remove the read-only, system, and hidden properties of SYSTEM.DAT and USER.DAT files in MS-DOS state:

attrib system.dat-r-h-s

attrib user.dat-r-h-s

4. Will SYSTEM.DAT, USER. DAT two files are renamed System.bad, USER. Bad:

Rename System.dat System.bad

Rename User.dat User.bad

5. Reboot the machine, the system will automatically modify: When booting, if Windows 95 cannot find the registry file, It uses the backup system.da0 and user.da0 as the registry file, and if the files are working correctly, the system changes them to SYSTEM.DAT and USER.DAT respectively.

If this is the third reason, you should do the following:

In Msdos. SYS file with the [Paths] section, or modify the [Paths] section. About MSDOS. SYS content, many articles have been described, here is not to repeat. Only the [Paths] section related to system booting is described here:

This part covers three items:

root directory of the hostwinbootdrv=< boot disk >

The default value is C, which indicates the root directory of the boot disk.

winbootdir=< the location of the required files for startup >

The default value is the directory specified at installation time (such as C:\WINDOWS), which lists the location of the files required to start.

Windir=

The default value is the directory specified during installation, such as C: \ Windows, which lists the location of the win 95 directory specified during installation.

If it is the third cause of the failure, you can refer to the above content with either editor to guide the packing directory (usually C:\) under the hidden file Msdos.sys editing, generally can solve the problem.

If the above method does not enable troubleshooting, there is a last resort: Run the setup of Win 95 from the original disk. EXE program to regenerate the registry file because all of the registry-related things may be having problems.
