The 8GB Surface Pro devices we bought a few years ago have become extremely sluggish and are nearly unusable. I recently found an even older Surface that had been sitting unused since 2023. It is still running Windows 10 without the latest updates, and it feels about as fast as it did when we originally bought it. Why does an older, unupdated installation seem faster than the same kind of computer after years of updates? Is the slowdown mainly caused by Windows itself, newer applications, background services, or something else?

There have also been specific software regressions. Some recent Windows components, including WebView2-based features, have reportedly caused unusually high memory usage on 8GB systems, and fixes may arrive through later updates. An unupdated installation can feel faster simply because it never received the newer services and features that consume those resources.
The operating system usually is not the only issue. Applications such as browsers, office suites, creative tools, and collaboration software have become much more feature-heavy over time. They often keep more processes running, load more web content, and use more memory. Antivirus scans, indexing, telemetry, cloud synchronization, and other startup tasks add to the load as well.
That is why simply blaming Windows can be misleading. The computer may be running a newer operating system while also running much heavier versions of every application.
A lightweight operating system can make the same hardware feel much younger. Some people get better results by installing a less resource-intensive Linux distribution, and on compatible devices basic features such as touch input can still work. That does not prove every slowdown is caused by Windows, but it does show how much the software environment affects perceived age.
A few different things can contribute. Modern Windows and applications generally use more memory and run more background services than they did several years ago. On an 8GB machine, Windows plus a browser, Teams, Outlook, and large Excel files can easily cause memory pressure. Once the system starts paging to storage, everything feels much slower, especially on older hardware.
That makes sense, but those same applications used to be usable on these machines. It sounds like their memory requirements have gradually increased rather than the hardware suddenly becoming slower.
8GB is increasingly a bare minimum rather than a comfortable amount for Windows 11 and current office workloads. A system with 16GB will generally cope much better, although adding memory cannot fix every problem. Removing unnecessary startup programs, checking for a nearly full or unhealthy drive, and looking at Task Manager while the machine is slow can help identify whether the bottleneck is memory, storage, CPU, or a runaway process.
So an update could improve things eventually, but another update could also introduce a new performance problem?
