The proper maintenance is required for having better performance with any kind of computer. The internet has become the huge source to download any thing you want that occupies more space on hard disk and making your computer into a lethargic one. Frequently check that how much space is available in your disk and store accordingly to increase the performance of your computer. You might have installed some software for temporary use and forgot to uninstall them. Deleting the unused program is different from uninstalling it, so perform uninstall operation in control panel to avoid problems to system files. Remove the temporary files in hard disk by performing disk cleanup in system tools. The browser will store the web pages which you gained access long time before also in the internet cache. Cleaning the cache memory on any browser is very simple, so perform this operation and save your hard disk space. To access the new mails in inbox quickly, remove the mails which contain more space for the faster access whiles you browsing over the mails. Always perform shift+delete operation to remove the files completely from your system. The normal delete operations will store the files in recycle bin that also slows down the process.
