From the 1st release of Windows 95 to the latest release of Windows 7, it is a common issue of all computers (regardless PCs or servers) running on Microsoft Windows OS that over time, the OS will become slower and slower, and the harddisk storage will also filled up with more and more junk files.
Advanced SystemCare by IObit is the tool to restore and maintain the performance of your Windows OS close to the moment it is freshly installed. There are 2 versions of it, the Free version with basic function, and the Pro version with tonnes of functions to clean, fix, optimize and tune up your Windows computer.
I have been using Advanced SystemCare Pro for more than a year, from Version 3 until Version 5 now. For each new version release, they introduced more and more functions, and it never fail in tuning up my Windows computers so far.
One of the beauty of this software is it can automatically and quietly perform its scan, fix and clean tasks when your computer is idle.
Just to share with you that now, there is a promotion for this software until 31 March 2012. You can get Advanced SystemCare Pro license for 3 computers, and a Windows Tweaks Guide eBook in PDF format, at the price of $12.97 only, which is 80% of their normal price. This price is even cheaper than my Norton Internet Security annual subscription fee.
The license will last for 1 year, and you get unlimited software update and upgrade as well as technical support along the period.
