Troubleshooting for a friend find many problems in Event Viewer. When in device manager, showing all, hidden devices, etc. find that more then 30 line items for Generic Volume Shadow Copies under "Storage Volume Shadow Copies" then another 3 line items under "Storage Volumes". Currently there are 2 internal hard drives on this system and 2 DVDs, with one external USB Drive. Is this normal? Totally unclear about why so many and how it impacts system performance and the many problems on this system such as DNS Client Events with tons of hits saying "timed out".
Thank you for your insight and help.
