If you have a home PC you should always keep it in “good shape”. There nothing more disappointing when your own computer can’t run properly when you’re trying to internet browse or keeps “lagging up” constantly and crashing.
You should update your computer whenever you have the chance or time. Or if you see any updates from your main programs telling you that you should update. Do it.
Also make sure to have a good antivirus. Viruses are obviously common while you’re browsing through whatever websites you do. If your computer is not up to date then you are more at risk to get viruses. Keep your computer up to date and always safety check it through your antivirus.
