A slow Windows PC is usually caused by too many startup programs, a nearly full or ageing hard drive, pending updates, malware, or simply too little RAM. Working through these in order resolves most slowdowns.
Trim startup programs
Open Task Manager → Startup and disable apps you don't need at boot. Fewer startup programs means a faster login and more free memory.
Free up and upgrade storage
Keep at least 15% of your drive free. The single biggest speed upgrade for an older PC is replacing a hard disk (HDD) with an SSD.
Update Windows and drivers
Install pending Windows and driver updates - they often fix performance and security issues. Then restart fully.
Check for malware and add RAM
Run a malware scan, and if the PC is still slow with heavy multitasking, adding RAM (to 8–16GB) makes a big difference. Cybergate can supply and fit SSD/RAM upgrades.
