Discussing OS key reuse and performance boosts in Windows 7
Discussing OS key reuse and performance boosts in Windows 7
I haven't received an answer to this question before, so I'll ask again. I'm using a HP notebook running Windows 7. They suggested using the built-in key from the notebook's operating system, and I intend to reuse it on my new computer as well as during a fresh installation on my current device. I'm worried that using the same key multiple times might make it invalid—like trying it on a laptop for a clean setup and then on a new PC, causing issues. Also, I want to know if a clean install would noticeably improve performance, or the gain would be small depending on various factors. Please let me know if this is too basic or if I missed something important.
You should face no issues using a Windows key from your laptop on your desktop, provided it matches the original version and you install a brand-new operating system on your laptop. Regular clean installs usually eliminate accumulated clutter unless you handle them manually.
It’s uncertain whether this will work, but it might if it doesn’t. You can always download a fresh operating system. Performance gains depend on background programs you run but rarely use—many users notice a noticeable jump in desktop speed, potentially from 0 to 1 frames per second in games. I’ve seen the new install strip unused files, so I’d suggest everyone do it annually at least.
It appears the issue occurs during updates or restarts when Windows flags it as non-genuine. Try opening Command Prompt as Administrator, type `notcopy` and press Enter—this should resolve the problem. Then restart your PC.
