salam. korang ada ketika masalah nak update VPC integration components? aku dah kena. pening kepala berminggu2.. sbb utama, sampai tak leh copy paste dan skrin tak enlarge kasi besar. solution mudah je. 1. Unistall Virtual PC Components 2. Remove the device that is unrecogonized from the device manager 3. Rename the following 2 files C:\WINDOWS\system32\DRIVERS\wdf01000.sys and C:\WINDOWS\system32\DRIVERS\wdfldr.sys 4. Restart the system pastu korang install lik. sure boleh nye. adios. rujukan: http://blogs.technet.com/b/asiasupp/archive/2011/08/04/error-on-upgrading-virtual-pc-integration-components.aspx
