Junk files in C drive after successful upgrade from vista to win7

It is recommended not to upgrade and reinstall

You can use software such as PC Manager to get rid of the junk.

The computer will become more and more stuck over time. The main reason for this is that the C drive of the W7 system stores a large number of files and occupies the memory. If you want to speed up the system, you can delete the Chinese part of the C drive.

However, the C drive has important files stored in it, and if you accidentally delete it by mistake, it will cause the system to crash. Refer to the ghost system base reinstall system tutorial, which can also make the computer very fast.

1. Turning off the system sleep function can release more than 3G space.

Right-click and select "Run as administrator" to enter the command prompt, and enter "powercfg -h off" to disable the win7 system hibernation function.

2. Turn off System Protection: Computer right-click Properties - Advanced Management Settings - System Protection, and select Off.

3. Transfer the right-click properties of the same computer as the virtual memory, and then click Advanced Management Settings - Advanced - Performance - Settings - Advanced - Change in turn.

4. Transfer the "User's Files" desktop and double-click the Administrator folder to transfer the "Desktop, Favorites, My Desktop, My Documents" folder here. Right-click on the property of the project you want to transfer -- position d: users administrator and you're good to go.

5. Adding motherboard memory modules and replacing SSDs can improve the boot time and running speed of the computer.

Let me explain it to you.

First of all: all of these zips are unzipped when you install DirectX (a platform that runs large 3D games and large applications), and can be deleted if you have installed them before and keep the land pack. If you don't keep it and you need this DirectX software (if you play big games), I highly recommend that you cut it all to a non-C drive and create a new folder to save it, and the files that need to be cut to the new folder are:

All compressed files + other files that are not folders. DXSup is the installer for this DirectX.

Secondly:The "26169" in these folders should not be a system thing,If it's not your own private files or installed programs,It should be useless,Of course, if you don't worry, you can open it and take a screenshot to show me。 Everything else should be useful.

If you don't understand, you can q me 407610061, I need the score very much, hopefully!! Thank you!!

All the compression software is removed to empty the hail out of the hard drive. 26169 file Min Defeat folder, amd, audioshell13, happychunnal folder, tddownload, word2007 folder (this folder, please ask if you have customized the installation location Zheng Nafan, if it is the source installer, you can delete it).

These compressed files can be deleted.

It's easy to reload the plate.
