If your old ageing Windows Laptop is crawling due to new windows update. Give it a new life in two best ways. One is free while other involves buying a new hardware. Better do both. Lets talk each one by one.
- Install a new OS called Chromeos. which is a browser based cloud centric OS backed up by google. For office you can use google office. Make a bootable pen drive. Try it from usb then install. Steps here.
- Second way is to buy a SSD drive. 120GB or 240GB depends on your budget trust me startup time, apps opening time & response would go so smooth. You can use existing HDD as external HDD(via ext casing) or can be installed in place of DVD rom (via caddy)
Better try both to give your laptop a hefty speed boost.
