Most entry-level IT support candidates don't fail on networking theory or security concepts — they fail on OS fundamentals: navigating Linux without a GUI, managing Windows file permissions, reading process tables, or understanding why a machine won't boot. Operating Systems and You: Becoming a Power User is built specifically to close that gap, and whether it's worth your time depends entirely on where you're starting from.
This is an honest look at what the course actually teaches, who gets real value from it, and when you're better off with something else. The question of whether operating systems becoming a power user is worth it has a real answer — it's just not the same answer for everyone.
What Operating Systems and You Actually Covers
This is Course 3 in the Google IT Support Professional Certificate on Coursera — one of the most-enrolled credential programs on the platform with over 2 million learners. That context matters: the course is designed to prepare people for Tier-1 and Tier-2 IT support roles, not to turn you into a systems administrator or kernel developer.
Over roughly 22–26 hours of material (self-paced), you work through four main topic areas:
Windows and Linux Filesystem Navigation
You learn to move around both operating systems from the command line: cd, ls, dir, pwd, absolute vs. relative paths, and how directory structures differ between Windows (C:\) and Linux (/home, /etc, /var). This is genuinely hands-on — you run Qwiklabs exercises in a real terminal, not a simulation.
Package Management and Software Installation
On Linux you work with apt and dpkg. On Windows you cover the traditional installer flow plus an intro to package managers like Chocolatey. You also learn to manage software archives (.tar.gz, .zip) from the CLI — a skill that trips up a surprising number of IT candidates in technical screenings.
Process and Resource Management
Task Manager vs. top/htop, killing processes, understanding CPU and memory usage from a troubleshooting perspective. This module is the most directly useful for IT support work — most Tier-1 tickets involve a "slow computer" where the real answer is a runaway process or memory leak.
User Management and File Permissions
Creating and removing users, understanding Windows ACLs, and reading Linux rwx permission strings (chmod, chown). File permission issues are the #1 source of "access denied" tickets in corporate environments, so this module has clear practical payoff.
Is the Operating Systems Power User Course Worth It for Your Situation?
The honest answer is: yes for beginners, conditional for everyone else.
Strong yes if you're a career changer with zero IT experience
If you've never opened a terminal window, this course is exactly calibrated for you. The Qwiklabs exercises give you real hands-on time without needing to set up a Linux VM yourself. The dual Windows/Linux coverage means you're not just learning one OS silo. And because it's free (Coursera audit mode), the risk is zero.
Conditional yes if you're pursuing the Google IT Support Certificate
If you're working through the full 5-course certificate, this is a mandatory module and skipping it means gaps in later courses. Complete it even if some sections feel slow — the cert has genuine job market value, particularly at managed service providers and corporate IT helpdesks.
Probably not if you already work in IT
If you can already write a basic bash script, troubleshoot a permission error without Googling, or describe the difference between a process and a thread, you'll find the first two weeks painfully slow. The course rating of 4.8/5 reflects beginner satisfaction, not depth of content. Experienced IT professionals are better served by something like the Operating Systems: Overview, Administration, and Security course, which covers privilege rings, memory protection, and OS security at a level this course doesn't reach.
Skip it entirely if you already have a degree or certification in CS/IT
CompTIA A+ holders, CS graduates, and sysadmins will cover zero new ground here. Your time is better spent on the security or networking layers of the certificate, or skipping the cert entirely for something more advanced.
What the 4.8-Star Rating Actually Reflects
With 75,000+ ratings and a 4.8 average, this is one of the most-reviewed free IT courses online. But a few caveats are worth understanding:
- Most reviewers are beginners — the population rating this course skews heavily toward people for whom any CLI exposure is genuinely exciting. That's not a knock; it means the course excels at exactly what it claims to do.
- The Qwiklabs integration gets specifically called out in positive reviews. Doing real tasks in a real terminal environment is more engaging than watching videos, and the labs hold up well.
- The pacing complaints in negative reviews are consistent: experienced users find weeks 1-2 tedious. If you know what a file extension is and have used a command line before, plan to skip ahead to the permission and process management modules.
Top Courses for Learning Operating Systems in 2026
The right course depends on your level and your goal. Here are the best options across the range:
Operating Systems and You: Becoming a Power User (Coursera)
The course this review covers — the best starting point for complete beginners entering IT support, with hands-on Qwiklabs exercises and dual Windows/Linux coverage. Free to audit; certificate requires a Coursera subscription.
Operating Systems: Overview, Administration, and Security (Coursera)
A stronger option for IT professionals who want depth on OS architecture, security models, privilege levels, and system hardening — goes well beyond the helpdesk-level content of the Power User course.
Introduction to Computers and Operating Systems and Security (Coursera)
A good pre-step if you need foundational computer literacy before tackling operating systems concepts — covers hardware, OS basics, and introductory security in a single course.
Using Python to Interact with the Operating System (Coursera)
The natural next course after becoming a power user — teaches you to automate OS-level tasks (file management, process handling, log parsing) with Python scripts. Part of the Google IT Automation certificate.
400+ Operating System Interview Questions Practice Test 2026 (Udemy)
Purpose-built for technical interview prep — covers OS theory questions (scheduling, memory management, deadlocks, virtual memory) that come up in SWE and systems engineering interviews, which the Power User course doesn't touch.
Intro to Operating Systems 2: Memory Management (Coursera)
Covers virtual memory, paging, segmentation, and memory allocation algorithms at a technical depth suited for CS students and developers who need OS internals knowledge, not IT support skills.
FAQ
Is Operating Systems and You: Becoming a Power User free?
Yes — you can audit it for free on Coursera, which gives you access to all video lectures and most reading materials. To complete graded assignments, earn the certificate, or count it toward the Google IT Support Professional Certificate, you need a Coursera subscription (roughly $49/month, or covered by Coursera Plus).
How long does it actually take to finish?
Coursera estimates 22–26 hours. In practice: beginners typically take 3–4 weeks at a few hours per day; people with some tech background who skip familiar sections often finish in 8–12 hours. The Qwiklabs exercises add real time but are where most of the learning happens — don't skip them.
Does this course teach Linux or Windows?
Both — that's one of its genuine strengths. The course alternates between Windows and Linux throughout each module, teaching the equivalent operation on both platforms side by side. This is more useful for IT support than courses that pick one OS and ignore the other.
Is it worth it if I already have CompTIA A+ or a CS degree?
No. The content is firmly at the "what is a file system" level and you won't cover new ground. Look at the OS security or memory management courses listed above, or pivot to Python automation if you want to extend your OS skills practically.
Will this course help me get an IT support job?
By itself, probably not — employers screening for IT support roles want to see the full Google IT Support Professional Certificate (all 5 courses) or a CompTIA A+. This course is Course 3 of 5; completing just this one leaves the credential incomplete. If your goal is employment, commit to the full certificate.
What's the difference between this course and the full Google IT Support Certificate?
This course is one module within the 5-course certificate. The full certificate also covers technical support fundamentals, networking, system administration, and IT security. For job search purposes, the certificate matters; individual course completions are typically not listed separately on a resume.
Bottom Line
Operating Systems and You: Becoming a Power User is worth it if you're a beginner, and not worth it if you're not. That's a more precise answer than most course reviews give you, but it's the accurate one.
For career changers and complete beginners targeting IT support or helpdesk roles: enroll, don't skip the labs, and treat it as a required step toward the full Google IT Support Certificate. The 4.8 rating reflects genuine quality at the beginner level, the content is practical, and it's free — there's no real downside to starting.
For anyone with existing IT experience: your time is better spent on the OS Administration and Security course for depth, or the Python for OS automation course if you want to build practical scripting skills on top of the OS knowledge you already have.
The question of whether operating systems becoming a power user is worth the investment has a clear answer: only if you're currently not one.
