A computer for working from home: what to choose and where not to save

The most common mistake when choosing a computer: looking at price and brand instead of tasks. "For working from home" can mean very different things:

• email, documents, spreadsheets, a browser, video calls: the lightest load;
• many tabs, messengers, Zoom or Google Meet calls at the same time, a CRM, accounting software: a medium load;
• photo and video work, design, programming, editing: a heavy load.

For the first two an ordinary work computer is enough. Expensive "gaming" or "professional" hardware is not needed. For the third you will need more memory and a more powerful processor.

I have been building and repairing computers since the early 2000s, and most often I see one thing: a person buys either a machine that is too weak and slows down after a year, or one that is too powerful and sits idle.

RAM is the computer’s "desk": the more there is, the more programs and tabs you can keep open without slowing down.

For most users in 2026, 16 GB is considered the recommended standard. For a main Windows 11 computer, 8 GB is usually no longer enough for comfortable work. That does not mean nothing will run on 8 GB, but the machine will have little headroom and will age faster.

An important point for laptops: in many modern models the memory is soldered to the board and cannot be added later. If you buy a laptop with 8 GB of soldered memory, you are stuck with it for the life of the device. So when choosing between "cheaper with 8 GB" and "a bit more expensive with 16 GB", the second is better in most cases.

If you already have a computer and wonder whether it has enough memory, check yourself: press Ctrl + Shift + Esc, open the Performance tab and choose Memory. If usage is constantly above 85% during normal work, you are short of memory.

For office work, calls and a browser you do not need a top processor. Mid-range is fine: Intel Core i5 or Core 5, AMD Ryzen 5 and equivalents, Apple M-series for Mac. The generation matters more than the name: processors that are too old may not be supported by new versions of Windows.

For working from home, the webcam, memory and SSD matter more than a big processor name. A laptop with a good camera, 16 GB of memory and a fast SSD will feel fast and look professional on a call even without the most powerful processor.

An expensive graphics card has no place in office work. A separate graphics card is needed only by those who play games or edit heavy video, and the most expensive mistake is buying a gaming laptop for office tasks: it is heavier, louder, drains faster and costs more for no benefit.

If you have many calls, these decide how people see and hear you.

• Camera. A good built-in 1080p camera is enough. If the built-in one is weak, an external webcam is inexpensive and greatly improves the picture.
• Microphone and headphones. A headset with a microphone gives a clean voice and removes echo. For calls this matters more than camera quality.
• Light. Sit facing a window or lamp, not with your back to it. I wrote more about light and sound in the article on phone video.

A good work computer does not have to be new and expensive.

A used laptop. Second-hand business-series laptops often turn out to be a good choice. For most tasks, including remote work, 16 GB of memory, an SSD of 256 GB or more and an Intel Core i5 of 8th generation or newer (or equivalent) will do. What to check when buying:

1. battery condition: it wears out and may last only an hour or two;
2. an SSD rather than a hard drive;
3. signs of opening, repair, damage to the hinges and case;
4. that the keyboard, screen, camera and ports work;
5. the serial number and no owner account locks;
6. the option to return or exchange it if something is wrong.

Do not buy "blind" from random sellers. If unsure, ask a technician to check the computer before paying.

Upgrading an old computer. Sometimes it is cheaper to improve an old one than to buy new. The most noticeable improvement comes from replacing the hard drive with an SSD and adding memory if it is not soldered. But there is a condition: the computer must be supported by the current version of Windows. Official support for Windows 10 ended in October 2025, so a machine that cannot run Windows 11 is better replaced than invested in.

A new computer needs setting up, and how it works for years depends on it.

1. Install all Windows updates and drivers from the manufacturer’s official website.
2. Create a user account with a strong password and turn on sign-in protection.
3. Turn on the built-in Windows protection and do not install several antiviruses at once.
4. Remove unnecessary pre-installed programs that slow down startup.
5. Set up file backup from day one.
6. Install the programs you need from official websites, not from "builds" and cracked versions.
7. Check account security: two-factor authentication, a password manager.

• decided what tasks the computer will do;
• 16 GB of RAM (or a conscious choice of less);
• an SSD, ideally 512 GB;
• a mid-range processor, not the most expensive one;
• a good camera and headset for calls;
• an external monitor, keyboard and mouse if you work a lot;
• a warranty, a receipt and the exact model in the documents;
• after buying: updates, drivers and a backup are in place.
