Getting an error ‘Generic Host Win32 encountered a problem’ in the midst of some programs.

Getting an error ‘Generic Host Win32 encountered a problem’ in the midst of some programs. Also the registry has been blocked and I cannot edit the registry using the ‘regedit’ command. When I run the ‘regedit.exe’ utility, a message comes up stating ‘The Registry editing has been disabled by Administrator’. 

The reason you are facing such errors is due to a Trojan, which has infected your operating system. You will need to install an antivirus, update it and scan/clean your entire hard drive. To enable registry editing you can try this trick:

• Open the Group Policy Editor by typing ‘gpedit.msc’ in the ‘Start | Run’ dialog box. Scroll down to the ‘User Configuration’   in the Local Group Policy Editor window. Expand the ‘Administrative Templates’   in the following branch in the left pane. 
• Click on ‘System’ under the   ‘Administrative Templates’ branch. 
• Search for ‘Prevent access to the   registry editing tools’ in the right pane and double-click it. 
• Now you should switch the status   of the entry by clicking either ‘Not Configured’ or ‘Disabled’ using the radio buttons.
• Click on ‘OK’ and exit the Group Policy Editor Tool. Reboot and check if the registry editor works.

Switch the status of the entry by clicking ‘Not Configured’ or ‘Disabled’ using the radio buttons.
