Computer repair companies in Thunder Bay are being swamped with calls now that Microsoft is no longer supporting the Windows XP operating system. Jaime Gratton of Northern Computer Innovations says they've been receiving several calls from concerned people who believe their computers will shut down. She assures them that is not the case, but that they will probably start noticing problems in the weeks or months to come. Gratton says they are recommending upgrading to Windows 8 or getting newer computer.
