We’ve all seen them – those ads on nearly every software website that offer to clean your registry or speed up your downloads. Many of us have learned to ignore them. Occasionally, however, you come across such an application that actually does what it says. It really cleans the registry, and it really can help repair your system. Such a program is IObit Toolbox. It’s a general purpose repair package reminiscent of the old Norton Utilities. It’s useful, portable, works on several versions of Windows, and to top it off, it’s free. /> id="more-20468"> /> Note: IObit Toolbox contains many applications. Many of them are small, simple tools that perform a single task. As such, those will be mostly ignored in this review in favor of the less common, or simply more interesting tools.

Google Chrome's sync features can be incredibly handy for those of use who run the browser on multiple computers. Every now and then, however, you may run into a problem. In my case, I had certain bookmarks which kept popping back up even though I'd previously deleted them.

Today I got an email from a reader, John, who was having a similar issue with his extensions. "Recently LastPass has found a way to stay in there, but all my other extensions are gone, no where to be found, not even at chrome://extensions," he wrote.

So, how does he fix this? I've tried a couple things in the past which seem to help.

1. Sign out of Chrome Sync and sign back in. To do this, click the wrench menu icon and then click options. Once the window appears, click the Personal Stuff tab and press Stop syncing this account. Confirm by pressing Stop syncing.

   This method will work best when you're not signed in to Chrome elsewhere -- so remember to close your browser on your secondary machine before you begin.

2. Change your Google account password. Also recommended as a quick way to kill 3rd-party app access to your Twitter account, a quick change of your Google password will break sync and give you a chance to start fresh. This link should take you to the password change page, or you can visit your Google Dashboard.

   This will prevent all your systems from re-syncing, regardless of whether or not you closed the browser first.
