After my computer is automatically updated, the capacity of the system disk is getting smaller and s

I don't know if there is a Vista optimizer, if there is, it will be easy to do.

It may be that your computer is poisoned, and it should be okay to reinstall the system, it should be a problem with the operating system!

Including Microsoft Windows 7 system, after a period of use of Windows system, the space of the partition where the system is located will become smaller and smaller, even if you do not install some common software to the partition where Windows 7 is located, the hard disk space will be reduced day by day. Although the reduction is not very large each time, and the encroached space is not very much (as little as a few MB, as much as a few GB), but the reason for the slow decrease in hard disk space is **?

If you are familiar with Windows 7 automatic updates, you should know the reason by seeing the screenshot below. That's right, it's Windows 7 that automatically updates the size of the folder, which causes the partition where the system is located. The space is getting smaller and smaller.

Go to the X: Windows Software Distribution Download directory (X is the drive letter of the partition where Windows 7 is located), if you find that there are a lot of files in it, and the volume is very large, then it is basically certain that Windows 7 automatically updates more and more files, and at the same time, they are not deleted after the automatic update, resulting in smaller and smaller hard disk space.

The advantage of this setup is that when the user is prompted for an update, you will make a trade-off based on the importance of the patch file that Microsoft is updating. What's more, this setting will also alert the user with each update if you should clean up the folders that are automatically updated.

2. Find [Disk Cleanup] in the [Property Panel], 3 click [Disk Cleanup], and then the [Disk Cleanup: Drive Selection] panel will pop up, then select [C disk], click [OK], you can clean up the disk, and wait until the scan is completed, you will see the [Disk Cleanup] interface, and then, select the useless files that take up a lot of space, and then click [Clean System Files] to free up some disk space (but this operation will not clean up the original system files, Only some useless files of the system will be cleared), as shown in Fig.

1 Find [Cortana] in the [Taskbar] in the lower left corner of the computer, and then, open [Cortana], and enter Disk Clean Up in [Cortana], in the process, you will find that the first processing function recommended by the computer [Free up disk space by deleting unwanted files], as shown in the figure.

2 Click [Free up disk space by deleting unwanted files], you will find that the computer will also pop up [Disk Cleanup], and then, still select [C disk], and then click [OK] to start disk cleaning, however, after the detection is completed, the [Disk Cleanup] interface that appears is different, and the [Clean System Files] option is missing, however, the detected files are more temporary files to install and occupy a large amount of memory, as shown in the figure.

3 Select [Temporary Windows Installation Files], and then the computer will prompt [Is it true to delete these files permanently], select [Delete], and then the computer further prompts [Delete the selected files, the computer cannot be restored to the previous version] Click [OK], after the deletion is completed, you will find that the computer C disk space (free space) is 7G more, as shown in the figure.

Why is the win7c disk space getting smaller and smaller.

Clean up the system update files.

Click to enlarge.

System patch updates and installers are installed on the system disk by default, and a large number of cache files generated when the software is running will make the system disk space less and less.

You can use 360 or other security software to clean up the patch, as long as the installation is completed, you can delete the temporary files generated by the installation of the patch or the patch file itself.

When installing the program, it is recommended to install the program under a disk other than the system hail disk, so as to reduce the occupation of the system disk in the empty space, and some programs will also produce other temporary files when running, which will occupy more system disk resources. Like win7 or a higher-level system, its installation requirements are explained, be sure to give the system enough space, the system itself will have system patches to play every once in a while.

Although there are many similar command operations on the Internet that can clean up the system disk in an instant, the space occupied by other programs other than the system installer will only be completely solved by installing other simple disks through what I said.

There is no need to reinstall the system, you can enlarge the C drive because your C drive is too small.

I 64-bit win7 c disk you see,I used to be c disk 50G was not enough,Later I directly expanded to 100G。

I'm going to install a win8 in the future.,Don't worry about the lack of space.。。 You can search for Partition Assistant. You can directly expand the partition of the hard disk, whether it is C drive, D drive, etc. His official website is:

There are also tutorials in it, I hope it can help you. In addition, the patch is installed, so don't delete his backup. If there is a blue screen or problem with the patch, you can't delete it without a backup file unless you reinstall the system.

Therefore, security software will not recommend deleting patch backups.

When the Windows system is updated, a lot of folders starting with $ will be left in the windows directory of the C drive, the more patches are updated, the more files are left, these files are left here to uninstall these patches, but after the actual patch, few people go to uninstall it, the patch is for security, and it is not safe after unloading, who still unloads it, so it can be deleted. These files are hidden files and need to be shown to be hidden in order to be seen (method: open a random folder, in"tools"menu"Folder options", in"Check"tags"Advanced settings"Medium-looking"Hide files and folders", selected"Displays all files and folders", OK), you can delete them all.

There should be some patched installers reserved in the C drive! At the same time, while installing the patch, some files will be installed in the system32 of the windows folder under the C drive.

Use the partition assistant to divide a part of the space from other partitions to the C drive, if you are not afraid of trouble, just remove all the updates, the update is useless, you are not a celebrity, no one attacks your computer, it is best to turn off automatic updates,

Some junk files in the system are very strange, especially temporary files, with those 360 and QQ butler are not clean, it is recommended that you use ccleaner software, there is a green Chinese version, scan it, you will find that there is still so much garbage.

Enter the C drive and clean it with 360 force.

The disk space occupied by the patch can be cleaned up by using Disk Cleaner as follows:

1. Turn on the computer, right-click on the C drive, and select Properties;

2. Click the Disk Cleanup button;

3. Select the service pack backup file from the pop-up dialog box and click OK to start the cleanup.

4. Wait for the cleanup to complete and close the properties dialog box.

This can't be helped, but the updated patch package can be deleted (as long as you don't uninstall it), and you can delete it with 360 or something.

The first thing to do after installing the system on your computer: turn off System Restore, the second thing: turn off automatic updates (window7 update), and the third thing:

Turn off the firewall,Whether it's XP or win7 or win8 to do this,Patches still have to be played,Use 360 to play it,After doing these, I estimate that the capacity of your C disk will not change too much,Win7 After installing the system9G,If it's outrageous,For example, it's 3 to 4 G,It's a bit exaggerated,So after installing the system, follow the above three steps,As a programmer,That's all I can remind you!

Disk Cleanup, deleting system files.

Clean up the useless software of the C drive, if it won't, use 360's software manager to remove it.
