I have been downloading Bitcoin Core for five weeks and made 69% progress.
First, I have to say this is
terrible performance.
The computer is all frozen/unresponsive and won't let me open anything up.
If you can't open for instance your task manager anymore, that's a Windows problem, not a Bitcoin Core problem.
I would have hit the reset button much faster than waiting for 4 days, but that's probably why I don't use Windows.My advice would be to start over, but not before upgrading your hardware. To compare performance: on my old Linux laptop with slow CPU but 16 GB RAM and Bitcoin Core's
chainstate directory on SSD (with the
blocks directory on HDD), I can sync the full blockchain from scratch in just over 24 hours. If you insist on running Bitcoin Core, and if your computer can handle it, I suggest to add at least 8 GB of RAM, and a solid state drive.
With your current hardware you're probably better off running a less demanding wallet (such as Electrum). Unless you have a specific reason to use Bitcoin Core.
