My nephew been worked on my sister old PC wanted to recovered all users videos, pictures, musics and files as he had lots of videos and pictures from his teenager years. It used my old AMD Phenom X4 9950 CPU, Windows 7 Home Premium, 4GB RAM and old Western Digital WD2500 250GB SATA2 300 hard disk. Last time PC was used in February 2014 included Windows Update but he struggled to recovered all files as Windows 7 ran very slow struggled with 4GB RAM and 250GB SATA2 hard disk, apps was unresponsive for a few mins so he found Windows 7 unusable and now he left his PC to me to sort it out to recovered all users files as he now back in the Army for a few weeks.
I had very interested week with my sister old PC to recovered videos and pictures for nephew. Tried to booted PC with onboard Geforce 8200 GPU but HDMI to DVI adapter didn't worked with no signal so I tried to installed old GTX 1070 card in and tried DVI port with adapter still not worked with no signal then used HDMI cable worked and I was very surprised to see ancient PC with old OCZ Z850 series PSU booted with GTX 1070 just fine and later I was shocked to see fully updated Windows 7 unusable with 4GB while memory usage was very high, struggled to run latest Chrome and Mozilla versions and 2-3 applications with apps froze and unresponsive every few mins made files recovery impossible.
Tried cloned hard disk to 1TB SSD on 250GB partition created and issue still same after reinstalled Windows 7 and Windows Update was fully updated. Installed Norton Security, Spybot and Malwarebytes to scanned for viruses and trojans then tried upgraded it to Windows 10 Home 1809 and incredible Windows 10 with latest updates ran blazed fast and very responsive with apps no longer froze every few mins on 4GB RAM.
Wow what a massive differences and huge improvements moved from Windows 7 to Windows 10. Didnt realised I noticed fonts on Windows 7 looked grainy while fonts on Windows 10 looked much better, very clean and sharper while Windows 7 had very poor DPI scaling and also task manager was very limited. Windows 10 task manager and DPI scaling are much better than Windows 7. Not surprised Windows 7 was horrible slowed with all Windows updates fully updated while Windows 10 1809 ran much faster with all Windows updates full updated.
Decided to installed Steam to see how well Prey and Resident Evil 2 run on 4GB RAM which is far below 8GB RAM minimum system requirement and I was very impressed it ran incredible fine with GTX 1070 on 11 years old ASRock K10N78FullHD-hSLI R3.0 motherboard with ancient OCZ Z850 series PSU, 1TB SSD, ancient AMD Phenom X4 9950 CPU and 4GB RAM.
