Here's my latest piece of advice on keeping your computer clean. CCleaner.
CCleaner (was Crap Cleaner) is a useful program.
Here's the link to their home page of Piriform CCleaner
Here's the link to download it CCleaner at FileHippo.
I use it to clean and remove browsing history and temporary files.
It has a one button approach. Nice and easy.
It cleans out temporary files and cookies if you want, from Internet Explorer and Windows.
CCleaner will also clean up files and history from Opera, Google Chrome and Firefox.
It has a registry cleaner, so don't go paying for one.
It also has a program removal tool.
This is very handy for removing those pesky tool bars that every piece of software wants to install.
Use this to clean out all your rubbish before you backup your computer now !
Keep yourself nice. Cheers. Si.
Checked for links and relevance, April 2014. Still very relevant for Windows XP and Windows 7
This is my site for links to Genuine Free Stuff as well as some useful advice. I use most of these programs regularly. It's good gear. It's all worth having.
** April 2014. Major revamp and update for relevance happening, especially now that support for Windows XP has ended, and now that we all are addicted to our Android phones. A lot of old stuff is going.
This post in particular started this whole website...
I have been building and using computers since about the Ice Age, from DOS 3 through to Windows 7.
I have been mucking about with mobile phones for quite some time, using Symbian S60 and then Android.
Press F8 at boot to start in safe mode - Windows XP and 7
To see the details of you computer, download, install and run 'Speccy' - shows Operating System, Firewall, Anti-virus and hardware.
