Why does Windows 10 take so long to install
Why does Windows 10 take so long to install
I often set up Windows 7 or 8 for my clients, since most dislike Windows 10 and prefer alternatives. A recent client brought in six machines with no operating system and asked me to apply a volume license for Windows 10. Typically, Windows 7 installs in about ten minutes on a slow 5400RPM 160GB SATAII drive, while Windows 10 takes an hour. The OS sizes are similar—my Windows 7 Professional ISO matches the Windows 10 Pro ISO in size. Why does it take so long? These six computers are consuming power while I install Windows 10, which would be faster and more efficient if done right.
The issue remains consistent, even though the setup completed quickly initially. After launching the desktop, the update process took significantly longer, lasting around 30 minutes or more.
The system uses a high-speed memory module designed to prepare data for installation, which can take several minutes to complete.
The ISO file maintains the same size, but it functions more like an installer or a compressed archive. You can’t execute a full Windows installation directly from it. It’s likely that Windows 10 is significantly bigger than Windows 7—or perhaps the installation process itself is problematic.
Windows 10 is really problematic. It fits the malware definition. These are office machines. The Dell Optiplex 760 Core 2 Duo E6450 with 4GB RAM (DDR2) and 250GB Seagate Barracuda SATA III DDR4 storage. That’s why. But Windows 7 is fast—my test install on my own Optiplex 760 using the same setup in W7 took about 10 minutes.
I've set up Windows 10 on devices similar to mine, which took over 20 minutes. <unpopular_opinion> It's unclear what the issue is, but once installed and configured, no one would want Windows 7 anymore. Skip the 300+ updates and poor SSD compatibility—Windows 10 is here to help you and your clients.
