How can I clean-install Windows without losing my laptop’s activation?

A clean installation may improve software-related lag, but YouTube alone should not normally make this model overheat. Check temperatures on battery and while plugged in, and look for background programs using the processor. If temperatures remain high after cleaning, investigate the cooling system before assuming Windows is the only problem.

The heat probably deserves attention separately. Check whether the fan is running and make sure the intake and exhaust vents are not blocked. Dust buildup can make the processor throttle, which causes the sluggish performance you’re seeing. Carefully cleaning the vents with compressed air may help, but if it still overheats, the laptop may need internal cleaning or fresh thermal paste.

Before wiping everything, confirm which Windows edition is currently activated and save your important files. You can also use a reputable key-viewing utility to record any product key as a precaution, although most newer laptops reactivate through a digital license rather than requiring you to type a key again.

You can reinstall Windows 11 using a USB installer and choose “I don’t have a product key” if prompted. Install the same edition that was already activated, usually Home or Pro. Once the laptop connects to the internet, its digital license should reactivate automatically because it is associated with the hardware and often stored in the firmware. Back up your files first, since a clean install can erase the drive.
