The implementation targets pre-Windows 8 functionality and leaves some features unimplemented, but establishes basic support after nearly a decade of prior groundwork. This follows other recent ReactOS milestones including the first NT6 system call and running Half-Life 2. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are Job Objects in the Windows kernel and why does ReactOS need them? Job Objects are kernel primitives that let groups of processes be managed and controlled as a single unit, handling resource limits, collective termination, and security restrictions. Modern Windows apps like web browsers rely on them for sandboxing, and various services and daemons also use them. ReactOS merged basic Job Objects support targeting pre-Windows 8 functionality, a milestone toward running modern Windows software. _Track open-source compatibility milestones like ReactOS's Job Objects work on daily.dev._ ### Can ReactOS run modern web browsers yet? Not fully, but support is progressing. ReactOS merged basic Job Objects support, which is required for browser sandboxing, though the implementation currently targets pre-Windows 8 functionality and some features remain unimplemented. This builds on other recent progress including the first Windows NT6 system call and the ability to run Half-Life 2. _Developers following Windows compatibility layers can watch ReactOS progress on daily.dev._ ## Similar posts on daily.dev - [ReactOS Starts 2026 With Another "Major Step" Toward Windows NT6 Compatibility](https://daily.dev/posts/reactos-starts-2026-with-another-major-step-toward-windows-nt6-compatibility-ixzwzorpp) · Phoronix · 2 upvotes · 0 comments - [ReactOS "Open-Source Windows" Reaches The Milestone Of Being Able To Run Half-Life](https://daily.dev/posts/reactos-open-source-windows-reaches-the-milestone-of-being-able-to-run-half-life-bccvvih3d) · Phoronix · 0 upvotes · 0 comments - [This open-source Windows alternative can finally run Half-Life 2](https://daily.dev/posts/this-open-source-windows-alternative-can-finally-run-half-life-2-iagjmfa0y) · XDA Developers · 0 upvotes · 0 comments - [ReactOS For "Open-Source Windows" Achieves Massive Networking Performance Boost](https://daily.dev/posts/reactos-for-open-source-windows-achieves-massive-networking-performance-boost-wws8hd8x1) · Phoronix · 1 upvotes · 0 comments --- Tags: [#kernel-development](https://daily.dev/tags/kernel-development) [View this post on daily.dev](https://daily.dev/posts/reactos-merges-support-for-job-objects-as-step-to-running-modern-windows-apps-accb0hnhs) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"ReactOS Merges Support For Job Objects As Step To Running Modern Windows Apps","url":"https://daily.dev/posts/reactos-merges-support-for-job-objects-as-step-to-running-modern-windows-apps-accb0hnhs","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/reactos-merges-support-for-job-objects-as-step-to-running-modern-windows-apps-accb0hnhs"},"datePublished":"2026-08-23T11:46:08.066Z","dateModified":"2026-08-23T11:46:32.001Z","description":"ReactOS merged initial support for Job Objects, kernel primitives used by Windows for managing groups of processes, resource limits, and sandboxing needed by...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/e5233aeae940a66d231e20b2d9c039f7?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/e5233aeae940a66d231e20b2d9c039f7?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/reactos-merges-support-for-job-objects-as-step-to-running-modern-windows-apps-accb0hnhs","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"kernel-development","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"ReactOS Merges Support For Job Objects As Step To Running Modern Windows Apps"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/reactos-merges-support-for-job-objects-as-step-to-running-modern-windows-apps-accb0hnhs#faq","mainEntity":[{"@type":"Question","name":"What are Job Objects in the Windows kernel and why does ReactOS need them?","acceptedAnswer":{"@type":"Answer","text":"Job Objects are kernel primitives that let groups of processes be managed and controlled as a single unit, handling resource limits, collective termination, and security restrictions.
