Frequently Asked Questions About Free System Utilities

Is it safe to use registry cleaners?

Registry cleaners like CCleaner are generally safe when used carefully. However, always create a backup before cleaning the registry, as incorrect changes can cause system instability. Most modern systems don’t require frequent registry cleaning.

Can deleted files always be recovered?

File recovery success depends on whether the data has been overwritten. Files recently deleted have better recovery chances. Stop using the drive immediately after accidental deletion to maximize recovery success with tools like Recuva.

How often should I clean my system?

Monthly cleaning is usually sufficient for most users. Clean temporary files when you notice low disk space or slow performance. Regular maintenance with tools like CCleaner helps keep your system running smoothly.

Summary: Maintain Your System with Free Utilities

In 2026, free system utilities provide essential tools for keeping your computer clean, optimized, and running smoothly. Whether you need disk cleaners, file recovery, or system monitoring, there’s a free solution for every system maintenance need.

A Walt Whitman Songbook – Song of the Rolling Earth for Voice and Piano

A Walt Whitman Songbook

A Song of the Rolling Earth for Voice and Piano
Music by Craig Pallett based on the Walt Whitman Text

A Whitman Songbook Cover

Now Available: at International retailers such as
Amazon
Barnes and Noble

A Walt Whitman Songbook contains 10 new musical works by Vermont based composer Craig Pallett. This songbook was created for Voice and Piano. It primarily explores Whitman’s work called A Song of the Rolling Earth, from the 1891-92 edition of Leaves of Grass. The composer has not altered the natural flow of the text. Due to the length of A Song of the Rolling Earth he has broken the text into 7 different songs. The composer has named these, The Earths’s Words, Amelioration, Never Fail, Three Hundred and Sixty-Five, Whoever You Are!, I Swear and Tones of Souls primarily to help the public and musicians reference each song. Though it can be presented as a full suite, performance time is 35 minutes, each song can stand on it’s own as an individual work.

Besides A Song of the Rolling Earth, the songbook includes 3 other Whitman works from Leaves of GrassLaws for Creations, On the Beach at Night Alone and France, The 18th Year of these States.

From the Composers Notes.

“I chose not to alter Whitman’s text in any way. This includes not repeating material or changing the structure of the actual text, both of which might make the works more “song–like”. I wanted to have a sense of churning piano rhythms and patterns with a folk–like melody. Whitman’s works that I chose are very rhythmically segmented verses many of them flow from one rhythmic structure to another. Sometimes only 2 verses flow in the same fashion, and then proceed into different ideas and forms. At times, there is a singular verse that has no rhythmic relationship to any other verse in his text.”

This music is dedicated to Steve Kaplan (1958-2003), who played many of the original keyboard parts which were recorded as midi files for ‘Heart Essence’, ‘Zen Walk’, ‘Beyond Words’, and ‘The Point on the Wall’. Hearing those recorded performances brought back the memory and joy of working with Steve so long ago, and we were inspired to use the original Midi data recordings to create new orchestrations and arrangements for those songs.

Four new Kindle Editions formatted for author Z’ev ben Shimon Halevi

Recently formatted and released four Kindle books by Author Z’ev ben Shimon Halevi for Kabbalah Society Books.

A Kabbalistic Universe
Revised edition
A Kabbalistic View of Existence
Author: Z’ev ben Shimon Halevi
A Kabbalistic Universe describes the origin and purpose of Existence in the scheme of the four Worlds of Emanation, Creation, Formation and Action, and with their various inhabitants. Drawing upon ancient, medieval and modern material, this book brings the kabbalistic tradition into the present. This revised edition, with its additional graphics, makes the Divine principles involved more comprehensible. Once the metaphysics are understood, then new perceptions will come regarding the structure and dynamics of Existence and the functions of the angelics and demonics, as well as organic life and human evolution.

Contains 84 figures & diagrams.

This book is a resonating imprint of truth and should be read by all students interested in this ancient wisdom. –The Theosophist

Introduction to the World of Kabbalah
An Overview
Author: Z’ev ben Shimon Halevi
This new book by Halevi is an introduction to the Tradition, enhanced by many illustrations and diagrams. It outlines the origins of Kabbalah in biblical, mythological and metaphysical terms that explain the origins of Existence according to Jewish mysticism. Kabbalistic cosmology and psychology are discussed, as are schools of the soul, true and false teachers and working methods, in order to reveal the process of evolution and its aim ‘to aid God to behold God.’ This book is a synthesis of Halevi’s works.

Contains 147 figures & illustrations.

‘This book appeals to the imagination and is a thought-provoking introduction to Kabbalah. Its illustrations are a stimulating boost to reading and clarifies the text wonderfully.’ –Freda Edis – Author of The God Between

The Way of Kabbalah
Revised Edition
A Primer
Author: Z’ev ben Shimon Halevi

The Way of Kabbalah, with its enriched diagrams, opens up the inner teaching of Kabbalah. Using the Bible, metaphysics and esoteric psychology, it sets out a way for the aspirant to approach the path of development and Self-realisation. The relationship between the body, psyche and spirit to the Divine is shown in the context of the kabbalistic tradition and contemporary working methods. Various interior processes are observed as consciousness rises through the seven levels of the mind into the Halls of Heaven. From here a wider and deeper view of Existence, and our place in it, can be seen.

Contains 57 figures and diagrams.

Contains 49 figures and illustrations.

‘It is impossible to imagine a more masterly modern textbook on its subject.’ –William G. Gray, writer of esoteric books.

The Kabbalist At Work:
previously published as The Work of the Kabbalist
Revised Edition
Theory and Practice
Author: Z’ev ben Shimon Halevi

This book is about kabbalistic working methods and the background to such effort. Here, theory and practice are set out against everyday life and history, as well as inner and outer processes related to individual and group work. The themes include specific exercises, the ways of Action, Devotion and Contemplation, past lives, and how a school of the soul operates. As a revised edition, it contains many new illustrations and diagrams which open up other dimensions to the text.

‘From the outset, the reader will recognise that this book is rooted in many years of personal experience.’ –Martin A. Shell
