A good many applications now collect "anonymous usage statistics" and transmit them to the developer. It is strongly recommended that you disable this. Read each applications Terms of Use/Privacy notice carefully and/or browse through its control panel looking for such an option. Programs that are known to do this include.
All of these programs do not necessarily enable this behavior by default, most actually ask you first and it is debatable whether these constitutes "spyware" per-se, however the following common program undoubtedly does.
Some MS Windows software and MS Windows itself can periodically check a remote server and see if an update is available, sometimes (as in the case of MS Windows itself) the software can automatically download and install the update for you. Although this results in a tiny amount of information disclosure, I.E. that you have version X of the software, we very very strongly recommend that you not disable this functionality. It is extremely important that all software be up to date for security reasons
It is vitally important that Windows be up to date and we actually recommend that you configure Windows to download and install all updates automatically without prompting you. It is almost equally important that your antivirus, antispyware (etc) programs be up to date and we recommend that you also configure them to download and install updates automatically without prompting you (most are already configured this way). Antivirus/Antispyware programs need to update their "definitions" lists at least every week.
If you are using UNIX, the administrator will either perform updates for you, or you will be prompted to install updates by the System. (On UNIX, the system itself provides the update mechanism, individual software does not need to run its own updater).
Websites can collect certain information from you, simply by you visiting them.
Vistua.com itself collects Search Keywords, IP number, time of access, country of origin, referrer, type of resource requested, approximate duration of visit (computed by very gross estimate only), browser UA (name, version, etc), OS and version, HTTP status code and other internally generated information including how long it takes the server to generate your page, and whether or not you request the file http://www.vistua.com/favicon.ico.
