If you enable the system recovery function, you can delete the restore point. You can create a restore point yourself, and then click Start-All Programs-Accessories, System Tools-Disk Cleanup-Other Options-System Restore, which will delete all restore points except the last restore point you created yourself.
In particular, the restore point will take up a lot of space, and of course there is virtual memory, but it must be set at this time, but you can switch to another disk, but you can make a lot of space as long as you tidy up the restore point.
Most people can't find it and it's scattered.

6, 30 seconds to clear the garbage from your computer (make your computer fly like a fly)
Do you find that the available space of your computer system disk is decreasing? Are you getting slower every day like the old monkey king?
That's right! During the installation and use of Windows, a large number of junk files, including temporary files (such as *), will be generated. Tmp and *. _mp), log file (*. Log), temporary help file (*. Gid), disk check file (*. Chk), temporary backup files (such as *. Old and *. Bak) and other temporary documents. Especially, if IE's temporary folder "Temporary Inter Files" is not cleaned for a period of time, the cache files in it sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuable disk space, but also make the system run at a snail's pace. I believe you can't stand this! Therefore, it is necessary to clear up the blockage of LJ files in time, keep the system slim and surf the Internet easily and smoothly! Come on, friends, let's go to cclean quickly now! Here are the steps. It's simple. Just two steps!
Click Start → Programs → Attachments → Notepad in the lower left corner of the computer screen, copy the following words, click Save As, select the desktop as the path, and save all files as the storage type, with the file name cleansystemlj.bat. Finish. Remember that the suffix must be. Bat, good! Your garbage cleaner has been made successfully!
Double-click it to quickly clean up junk files in less than a minute.

Eight. There is also one that can increase memory. I'm IE8. Toolbar -IE Options-General-Check the box under Browse History-Delete-Check All-Delete-OK,
Eight. The key is that you can't load too many items, which is mine, and how to optimize it is also because of this, that is, there are too many things in your program, or there are too many things added or deleted in your program, so you can't bear to delete them. Therefore, deleting some useless or uncommon items can improve the network speed. Another point is not to put everything on the C disk, which is the system disk. Small memory, slow network speed, 360.
1. Delete the installation program of NVIDIA graphics card (2 G spaces can be cleared).
1, and the paths are: c: \ program files \ NVIDIA corporation \ installer 2 and C:\NVIDIA.
2. The installation program of 2.NVIDIA is stored in these two directories. It can be deleted manually without affecting the function of the graphics card. The total size is about 2 g.
The second is the search service directory of Windows itself (it can be emptied around 500M).
1, the path is: c: \ programdata \ Microsoft \ search.
2. This directory stores windows index files, and the search service of WINDOWS is similar to google Desktop, which exists for the convenience of users. But, on the whole, it is of little use. You can manually shut down the windows search service and delete the search directory.
III. Office installation source files (about 1G space can be cleared)
1, the path is: C:\MSOCache.
2. This directory is the installation source directory of windows Offices. The main purpose is to facilitate the addition of components in OFFICE in the future. If you don't modify OFFICE or have an installation disk in the future, you can clear the directory. You can clean up about 1G space for drive C. (Note: If it is not in the C drive directory, the MSOCache directory is the root directory of the partition slot where OFFICE is installed.)
Fourth, winsxs directory cleaning.
1, the path is: C:\\Windows\\winsxs.
2. This directory is complicated (don't clear all the contents of this folder directly), and most of the contents can't be deleted. However, temporary system update files and system update installation files stored in C:\\windows\\winxsx\\temp\\ and C: \ \ Windows \ Winxsx \ \ ManifestCache directories can be deleted. In addition, there are a large number of redundant update files in this directory.
3. If users are familiar with the WINDOWS 7 operating system, they can choose to use the mklink /j command launched by WIN7 to move the directory.
4, the use method is as follows:
MKLINK [[/D] | [/H] | [/J]] Link target
/D Create a directory symbolic link. The default is file symbolic link.
/H Create hard links instead of symbolic links.
/J Create a directory join.
Link specifies a new symbolic link name.
The target specifies the path (relative or absolute) referenced by the new link.
There are system files on drive C. Manual deletion is not recommended. Otherwise, the system will not start. It is recommended that you right-click the letter of drive C and select Properties, which contains disk cleaning. After execution, you can cclean it, or you can uninstall some unused programs in adding and deleting programs to save storage space.
What files can be deleted from drive C of win7 system? When to delete it manually?
Get a WIN7 optimizer, and then clean up the garbage with one click, and almost delete it.
