There is no single built‑in “one click” export for exactly that custom dataset, but you can get close from the console and, for full control, use a SQL query on the OCS database
Go to All Computers → Inventory / Search
Build a query with criteria you want (or simply “all computers”), then use the column selector to add:
Computer name
User logged in
Memory, processor, disk info
Operating system
These fields are available in the standard search parameters.
Run the query, then use the export function (CSV) from the result list. OCS can export inventory query results to CSV, which you can open directly in Excel.
This export will not list all installed software per machine in the same row; software is a separate table and is usually reported either per machine detail or via software‑centric reports
For a full “flat” CSV with basic hardware, OS, and software like Microsoft Office / LibreOffice, you can query the OCS MySQL/MariaDB database directly and then redirect the result to CSV
