The HP Laptop 17 cp with Intel Celeron N4500 runs slowly after a Windows 11 update. The dual-core Celeron N4500 has limited performance even under normal conditions. A Windows 11 update triggers multiple background tasks simultaneously that can saturate the CPU and slow disk access for extended periods.
Wait for background update tasks to finish Do first
Open Task Manager (Ctrl + Shift + Esc) and watch the CPU and Disk columns. After a Windows 11 update, Windows Update, Delivery Optimization, and Windows Defender all run at once. Wait for these to drop below 10% before drawing conclusions about performance.
Disable Delivery Optimization bandwidth hog
Settings → Windows Update → Advanced options → Delivery Optimization → Advanced options. Enable “Limit how much bandwidth is used for downloading updates in the background” and set to 25%.
Set Windows Update to Active Hours
Settings → Windows Update → Advanced options → Active hours. Set your active hours to your typical work hours. Windows 11 will schedule heavy update activity outside active hours, keeping the Celeron N4500 free during use.
“My HP Laptop 17 was nearly unusable for two hours after an update. Waiting for Windows Update to complete and then setting Active Hours kept it usable going forward.” — Norsimah, Kuantan
