Older models take ages to boot and open documents; deep software‑level streamlining can significantly improve performance. Our on‑site service disables unnecessary startup programs, turns off non‑essential visual effects and background services, adjusts processor scheduling for background services, and defragments HDDs or manually TRIMs SSDs. We also suggest removing redundant browser extensions and memory‑resident utilities. Since each old PC has a unique bottleneck – from insufficient RAM to CPU thermal throttling – a deposit is required, and the final fee is based on the actual streamlining content and performance gains, measured by time spent.
