The main hard disk temperature of Acer 4720z is about 55 degrees.

It is dual-core, but it is cool and sharp. Your pre-installed vista should be the home version. Personally, I think there should be no problem running the game. Is your high temperature blocked by the exhaust fan, or is it because your computer has been bought for a while and there is too much dust in it? I suggest you go to the seller to clean it up for free. If you don't have the home version of vista installed, you may have turned on vista special effects, such as the 3d desktop, so you need to turn them off, or your cpu will be overwhelmed. Another possibility is that there is something wrong with the owner. Hehe, run the game and feel whether the exhaust fan is very hot. I suggest you download the latest master control or use other cpu detection software to see if the temperature is still that high. Of course, if you have done all the above operations, but you still haven't cooled down, you can also try cpu cooling software, such as cpu cool.

The above is about using vista. If you think vista is not easy to use or you are not satisfied with it, then you can of course switch to xp, buy a disk and install it. But personally, I think you'd better use vista. xp is a bit backward. Hehe, I use vista, and mine is Acer 4720g. It works well and I like it very much.

I don't think it is necessary to use such a big hard disk, if you are a notebook. Because the bigger the hard disk, the greater the power consumption. Of course, you can change the 160g interface. Just look at your current interface. Whatever it is, it should be statistics.

Off-topic, the FileRepository under Vista is a monster, which is full of its own drivers. Most of them don't need it, and some of them have brought their latest drivers. Therefore, I sorted out a part of the catalogue that takes up a lot of space and listed the startup manufacturers. You can choose whether to delete or keep it.

We are not allowed to change the file repository directory. So control yourself. Please note that this directory should not be deleted! Getting control is relatively simple. Open Vista Optimizer, click the system settings above, click the right-click menu on the left, click the add right-click menu above, and select "Administrator gets ownership", but I suggest using software to get administrator ownership, such as Vista Optimizer.

Now start analyzing the contents of the directory c: \ Windows \ System32 \ DriverStore \ File Repository:

1. Printer driver:

The new printer has the latest version of the driver downloaded by itself, so most of them can be deleted. However, some users of old printers can choose to keep them. These old printers may have stopped updating drivers long ago. Therefore, here is a way to get the Vista version driver. Most printers are unknown brands, such as Lanier. Just delete it. All printer drivers take up nearly 800M of space, so I deleted them, because I used official drivers, so there is no need to keep them.
