similar posted on windows os forum my xp pro sp3 installation has developed some bad behaviour lately. it's an old install, maybe 4 years. but well maintained, all updates, anti-malware, firewall etc. but these days it will not see my digital camera will not install any new hardware (printers, mice) will not uninstall some software restarts during reboot otherwise, it runs sweetly and fast! i have done the eight steps just in case. none of the anti-malware scans showed anything. could not uninstall earlier versions of java (updates 5 and 7) because "error applying the transforms. Verify that..." must be a symptom of something... thanks for looking anyway!
