Toshiba Technician Says, "Don't Install Windows 7 Updates"

Just finished talking to a Toshiba tech support person. I called because my six-week-old Toshiba Satellite L745 laptop has developed a problem: there is a slight delay between keyboard commands and their execution in every program I use regularly (Word, Outlook, Quicken, etc.). For example: I'm in Microsoft Outlook and I double-click on the name of a saved task. Instead of opening instantaneously (as happens on my desktop, which has a slower processor, less memory, and a smaller hard drive), I get the hourglass for a second or two before the task opens. Or else a dialog box appears asking whether I want to archive my old items in Outlook and when I click the No button, the dialog box lingers there for a second before closing.

Toshiba says this is an issue they've experienced and it is caused by Windows and other "third-party" updates using up system resources. I should not accept or install those updates! They want me to perform an entire reinstall of Windows 7 Home Premium and never allow another update.So (1) if the problem is the Windows (and other) updates, then why am I not having the same problem on my desktop computer (running Vista, but accommodating updates with no problem) and (2) if all these updates are not really necessary (according to Toshiba), then why do companies keep producing them?It has taken me weeks to get this laptop customized and configured with the programs and content I need to use on it. If what this tech support person tells me is true, then will I have this problem on any computer I buy that runs Windows 7?
