This is a small bug in the Windows 2000 professional operating system. I am using the same OS for my home PC. When I get cinnected to the internet within minutes I get an announcing the corruption of error in svchost.exe system program. Due to this none of the web-pages can be saved for after-review. Editing options like copy-paste of the matter do not work at all. Only alternative remain is to entireley restart the whole process of rebooting. I found this to be very annoying. I would be glad if this bug could be fixed. However this problem is not seen in Windows XP/Me/98. But the problem with these OS are the manual settings of Environment variables.
