How to Install Squid on CentOS 7

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows and is licensed under the GNU GPL.

Backup Windows License Key

You can backup your Windows license key through the following VBscript. Please copy the following code in source and save as *.vbs. In additional, it can export the text file with license key to your desktop for backup purpose.
