Various software can have speeding effects on computers, it can have some services running in the background and thus take precious resources slowing the whole system. If you are not using software, uninstall it.
If you are using your computer for basic tasks there is no really need to install the latest and best. A lot of new software will require new hardware and things that offer are not so much better nor even required to justify the upgrade. Let us take office, for example, if you are using it to just write some text and not using any advanced options there is really no need to switch to a newer version, the old one will do just fine tasks that you are in need of.
Now this fits in the domain of upgrading your hardware but still it is much cheaper than replacing the whole laptop. Windows 10 works much better with SSD and SSD itself is faster than your standard HD, especially if it is slower model spinning in only 5400RPM. Operation of HD replacement is simple and straightforward and anyone can do it but the benefits of replacement will be visible right away. With a new SSD instead of an old mechanical one, you will have the feeling that you actually bought a new laptop.
This is basically the last thing you can do in order to speed up your old laptop that will not break your bank account. Upgrading RAM was always the thing that can push your computer to have more power and to behave better while you are doing tasks. One important thing here is to first see how much RAM you have in your computer. If you are packing already 8GB then upgrading will not do much but if you have only 4GB, raising it to 6GB or 8GB will be beneficial. Also, check if the model of the laptop supports more RAM in the first place.
We have covered here a vast array of options in order to get your laptop back into the game with variability between hardware upgrades to taking care of your software. Whatever option you choose to do it will speed up your computer but among all of them, replacing the hard drive will do the most.
