My computer has regressed over time in performance. Maybe it's because I have installed a lot of programs I'm not sure but the os is slow to shut down. I get message Waiting for background programs to close and it was explorer.exe. As matter fact explorer.exe is really causing issues in os. Crashing frequently, hogging resources, its frustrating! What is wrong with the os? I know Windows 7 is not perfect os but is this normal?
Regressed is not right word sorry. Actually windows 7 performs reasonably well it's just when it starts up or shutdowns it takes more time now then ever before. I guess it's normal when I first installed the os it started up and shutdown in no time.
Good News everyone. I found out the culprit that was slowing down the os. It was this strange file called sqlwriter.exe. It was located in roaming app data folder and I deleted it. Since I deleted the file the os is noticeably faster. It did not appear to be a virus, it was some file from Microsoft that somehow got on my computer perhaps through windows update I guess. Glad I solved issue :)
