Impact of modifying System registries and significant tips for data recovery in windows

Event Viewer is a critical component usually found in Window’s NT line of operating systems. It keeps essential information about all security and system events in three types of logs, including Application log, Security log, and System log. For defining a uniquely identifiable event of the system, the Event Viewer makes use of event IDs. You should continuously monitor your log files for gathering suitable information about all potential Windows security events. Sometimes, the event viewer fails to open up and displays a few error messages on your screen. This happens because of corruption in the event viewer log files. To overcome this problem, you may require modifying your system registry, which indeed could cause critical data loss. To prevent such a catastrophe, you need to go for Windows data recovery through a reliable third-party utility.

For instance, you may come across any of the following error messages in your Windows Event Viewer:

“The handle is invalid ”


“Dr. Watson Services.exe
Exception: Access Violation (0xc0000005), Address: 0x76e073d4”


“Event Viewer
Remote Procedure Call failed ”


The above errors occurred because your system contains a damaged or corrupt ‘.evt’ file. To resolve the issue, you need to modify the system registry. You should make changes to the system registry only if you are an advanced Windows user, as it might lead to critical data loss.

In case you encounter data loss, you should use an updated backup to restore your lost data. However, if the backup is missing, use an efficient Windows data recovery software. Initially, try to follow the below mentioned resolution steps.


You can resolve the issue by modifying the registry as follows-

  • Click ‘Start’, ‘Settings’ and then select ‘Control Panel’.
  • Now, double-click on ‘Services’.
  • Specify ‘0x4’ as the Startup value for the following registry key-
  • “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog”
  • Restart the system and rename the damaged ‘.evt’ file stored at:“%SystemRoot%\System32\Config”
  • Provide the original startup value ‘0x2’ to the modified registry key.

If the problem still persists, you should take help of third-party recovery software. These software are proficient in recovering every piece of lost, deleted, or formatted information from your Windows-based system. They perform recovery from FAT, NTFS, and exFAT file system based volumes. Moreover, they are compatible with Windows 7, Vista, Server 2003, XP, 2000, and NT4 (SP6).
