Open
My Computer and click
Tools>Folder Options. Click on the
View tab. Under
Files and Folders remove the check from "Automatically search for network folders and printers". Click OK. Switch off your wireless connection (laptops with built in wireless usually have a button for this, if it is an add-in card, remove it.), and reboot your computer. Did this speed up your boot-up time?
If not try this:
- Open Control Panel and double-click the User Accounts icon.
- Click Create a new account.
- Type a name for the new account and click Next.
- In the Pick an account type dialog box, leave Computer Administrator selected and click Create Account.
Click Start>Log Off>Log Off then log on using the new account. After you have done this restart your computer and log in to the new profile. Did this speed up startup at all?
