Answer 2

You can download ccleaner for free here: http://bit.ly/1Bk5V5C

First open CCleaner
Go to the Cleaner tab and you will be confronted by a very confusing lineup of checkboxes.
To make this brief, below is my recommended setup:
Under internet explorer check temporary internet files, cookies, and last download location. Most users don't really need this stuff. keep history and bookmarks unchecked, history is a maybe, but you don't want to lose bookmarked sites. You can normally leave Windows Explorer, System, and Advanced alone.
Run CCleaner and it will start deleting files.
afterward it will present you with a list of the files deleted, you really don't need to go through it as it will be several pages long.
The registry cleaner is recommended for slightly more advanced users. Use it after uninstalling programs as they will often leave behind incorrect registry entries.
If you decide to run Registry cleaner then review the items detected and always back up the registry (I keep a folder aside for this)
The Tools tab lets you uninstall programs and set startup programs. Why do you need this if Windows has all of these features? Especially with Vista Home Ed. The windows defender software explorer( startup programs) doesn't pick up some entries (however software explorer is easier to use).
Using CCleaner to uninstall programs and then check for leftover registry entries takes less time.
Under Options you can determine how CCleaner cleans your files. I leave this alone.

Answer 3

The past progressive is used to describe an action that was interrupted by another action. The action that interrupts is in the simple past. Use while with the action in the past progressive or when with the action in the simple past. The choice of while or when depends on what you want to emphasize. While emphasizes the action in progress (the background action) and when emphasizes the interrupting action. Also, the clause at the beginning of the sentence is the more emphatic.

Example:

Professor Tanaka was correcting papers when the bell rang.
When the bell rang, Professor Tanaka was correcting papers.

OR

The bell rang while Professor Tanaka was correcting papers.
While Professor Tanaka was correcting papers, the bell rang.

Answer 4

WHILE
While and whilst are conjunctions whose primary meaning is "during the time that". An example is:

The days were hot while we were on vacation.


WHEN
When is part of the 5 terms used to describe a situation... Who? What? When? Where? Why?

Answer 5

We use when, not while, to talk about something that occurs at the same time as a longer action or event that is described in the main clause:

I was asleep in my chair when Dora rang to say she wasn't coming home.

We use while rather than when to describe the longer action of two events or to talk about two longer actions that go on simultaneously:

Dora left a message on the voice mail while I was asleep in the chair.
