The right time to buy a new PC is when your current one is costing you time, causing reliability issues, or can’t stay secure/up to date—not just when it “feels old.” In 2026, the biggest hard line is that Windows 10 support ended on October 14, 2025, so if a machine can’t run Windows 11, that alone is now a very strong reason to replace it (or retire it from internet-facing use). The short answer Buy a new PC when one (or more) of these is true: - It can’t upgrade to Windows 11 - It’s slow enough to waste your time daily - It has frequent crashes / blue screens / weird errors - The battery is bad (for laptops) and replacement isn’t worth it - It runs hot / loud constantly - Repairs are getting close to the machine’s value - Your work needs changed (more tabs, more apps, remote support tools, bigger files, AI, video, etc.) Microsoft’s own “time for a new PC” guidance specifically calls out signs like: - Can’t get the latest updates - Noisy fan - Battery doesn’t last - Frequent PC errors / blue or black screens Biggest 2026 reason: Windows 10 is done If you’re still on Windows 10: - Windows 10 support ended October 14, 2025 - Microsoft says to move to Windows 11 for ongoing security and features - Microsoft 365 apps on Windows 10 keep getting security updates only through October 10, 2028, but Microsoft still strongly recommends upgrading the PC/OS to avoid reliability/performance issues over time Practical rule: If your PC cannot officially run Windows 11 That’s one of the clearest signs it’s time for a replacement. For the kind of client-facing / remote-support work you do, I’d treat that as a business risk, not just a convenience issue. Best real-world signs it’s time to replace your PC 1) It’s costing you time every day If it: - takes forever to boot - stalls opening Outlook / browsers - chokes on remote tools + tabs + Office - drags during updates - hangs during backups / OneDrive sync …that lost time adds up.
