Why does Windows 10 take so long to install
Why does Windows 10 take so long to install
Same here. Files are unpacked and ready fast, but it still feels slow reaching the desktop. I’m curious what’s happening. My laptop with a 2GB RAM and Atom CPU took two hours for 10 installs, while my main machine takes over an hour from boot to desktop—especially since both use the same HDD. The SSD was bottlenecked because the light stayed on constantly. I installed Windows 7 on a friend’s OptiPlex 760, which took about 20 minutes from startup to open. The files were on the same drive but a different partition.
I just set up a fresh version of Windows 10 on my laptop (version 1703 with all updates from June and before). From when I chose the install location until the desktop appeared, it felt like about half an hour. Then because updating Windows is so slow, it took another hour and a half to finish the update.
It seems the installation attempts to fetch updates while running, which can slow things down. Windows update is inherently slow, and frequent small changes put a strain on storage devices. Even with modern SSDs, the installer still faces performance challenges.
On average, these six Optiplexes require about two hours for full installation. After that, it takes an additional hour to get ready for the desktop.
