Registry recovery in case of Windows startup failures

Ideally, when you turn on a Windows-based computer based on a family of cores that are still running on NT, the system boots up in normal mode. If the download is successful, the standard Windows shell - Explorer (in the explorer.exe process manager ) automatically starts .

But sometimes, as a result of some phenomena, the boot process can be broken, which will lead to damage to the operating system and the inability to work. The most frequent causes of the problem are: power failure and malicious programs, actions by third-party users. Restoring the registry to a normal state is exactly what can quickly help in this case.

There are different levels of damage to the system. If the stage of the splash screen is over and the color design of the Explorer shell is displayed, and then the boot does not take place, then you can limit the procedure to rollback to the previous state of the system. To do this, when loading, press the F8 key on the top of the keyboard, which initiates a menu in which you need to select the "Safe mode" option . In the "All Programs" menu, select "Standard", then "System Tools", item "System Restore" (rstrui.exe). Choose any system restore point before the date of the ill-fated failure and reboot. If you are lucky and the reason is really in the registry, which is often enough, the system is loaded as a result of these actions.

There are also fatal crashes when the download does not happen at all. Typical symptoms are a blue screen at boot time or a black screen indicating that the system can not load part of the registry. No problem. A pair of magical passes - and the system works again! But here, like any business, also has its own subtleties. After all, the cause of fatal crashes can be not only software collisions, but also hardware problems (corrupted memory RAM modules or the basis of the system is the motherboard). Before attempting to fix the system, they should be checked. To do this, open the case and make sure that the capacitors on the motherboard are in order. Then try to boot with one or another RAM module. If the module is only one, then replace it with a new one; If this is not possible, test the RAM memory with the memtest86 utility (you can find it on the excellent Hiren's Boot CD for PC resuscitation procedures).

None of this helped? Then the problem is really in the registry. Try an elementary trick with the loading of the last working state, which includes the restoration of the registry, or rather, a small part of it (one of the items in the menu on F8). Did not help? Then we proceed to the "reinforced concrete" version - we are restoring the registry. To access the file system, use the Recovery Console. We take the disk with the Windows distribution, wait for all the drivers to load and press the R key. We exit into the recovery console. Then replace the damaged "registry hive" with the copy command, specifying the path to C: \ WINDOWS \ REPAIR \ BOOST_RESTER_NAME, and the destination path will be C: \ WINDOWS \ SYSTEM32 \ CONFIG

This is enough to boot the system in its original form. In the simplest case, the work on this will be completed if the SYSTEM is corrupted - it will only be necessary to manually re-tell the system the path to the device drivers. Most often this can serve as a temporary measure only until the happy moment, until you get the right to read the System Volume Information directory, where the system's snapshot is stored, which allows you to restore the registry (restore points).

To access, go to the "Control Panel", there is looking for the icon "Folder Properties". We remove the checkboxes "hide protected system files", do not forget about the docket "use simple folder sharing". We go to the C: drive and watch the coveted "System Volume Information". In the properties of the folder we go to the bookmark under the name "security" and do the operation of adding the current user to the list. Accessed.

We go in System Volume Information and into the whole tree of subdirectories. We are looking for RP (Recovery Point) as soon as possible, we go to the subdirectory Snapshot. Copy the bush of the type _REGISTRY_MACHINE_SOFTWARE to us in C: \ WINDOWS \ REPAIR. We load the Recovery Console and use the "copy" command to copy the registry hive from C: \ WINDOWS \ REPAIR to C: \ WINDOWS \ SYSTEM32] CONFIG. A few seconds after the restart, everything works again! Registry has been restored. The peculiarity of the versions of WiNDOWS Vista and Seven is the location of the backup registry files in the directory C: \ WINDOWS \ SYSTEM32 \ CONFIG \ REGBACK, which simplifies the above algorithm to one action (moving the registry hive file from the Regback folder to the vital directory for the operating system C: \ Windows \ System32 \ Config. Thus, it is easy to restore the Windows 7 registry.
