The 70-660 exam is how Microsoft decides who earns the Microsoft Certified Technology Specialist (MCTS): Windows Internals certification, which sits at the Specialist level. It measures practical command of the Microsoft TS:Windows Internals objectives — the skills you'd actually use on the job — which is why it carries weight with employers in a competitive market. Candidates do best when they treat the exam as a skills check, not a memory test.

Microsoft organizes the Microsoft TS:Windows Internals syllabus into 5 domains, opening with I/O System and Storage (20%), Security and Configuration (20%), and Debugging and Troubleshooting (20%). Those weightings are a gift: they tell you where the points concentrate, so you can front-load the domains that decide your score. The full breakdown lives in the exam topics section above — build your study plan around it.

Expect 45–68 questions within 120 minutes on the Microsoft TS:Windows Internals exam. Treat that ratio as a pacing contract: work out your per-question budget now, and during the exam, flag anything that threatens to overrun it and circle back later. Candidates who rehearse this under a real timer — the DumpsActual test engine runs one on every mock exam — consistently finish with time to review instead of guessing through the final questions.

You'll need 700 (scale 1–1000) to pass the Microsoft TS:Windows Internals exam, and a seat costs Retired, historical price ~$125–$150 USD.

The reliable method is timed self-testing — run DumpsActual practice exams until your scores sit clearly above the passing mark across several sessions, then register. You're not buying certainty; you're refusing to pay for the same exam twice.

DumpsActual's 68 practice questions cover these formats, so nothing on your screen in the exam room is a first encounter.
