In fact, whether installing win7 or win 10, the computer will always be slower and slower, because there are many invisible things that we don't set often, which will slowly slow down our use speed and reduce our experience, because it is too! Slow down! Yes!

Today, Bian Xiao teaches you some small ways to restart your computer.

One reason why computers are slow: CPU utilization is too high.

Many times, netizens will encounter a strange computer problem. Not too many things, the CPU utilization rate of Win 10 system is 100%. Obviously, this is because the CPU utilization rate is too high, which leads to the computer being stuck.

If you don't open too many programs or the CPU utilization rate is still high after closing the software, you can try the following methods to solve it.

1. use Win+R to open the run dialog box, and then type? regedit？ Command, press enter to open the registry editor, as shown in the figure below.

2. After opening the Win 10 registry, expand HKEY _ Local _ Machine → System → Current Control Set → Service → Time Agent in turn, then find start on the right and change its value from 3 to 4.

Modifying this value will affect Cortana's performance, which is one of the possible reasons for high CPU utilization. You can refer to this method if you don't use Cortana.

The second reason why the computer slows down: the space on disk C is getting smaller and smaller.

In addition to the high CPU utilization rate, there is another reason that will slow down the computer, that is, the space of drive C is getting smaller and smaller, the space occupied is getting bigger and bigger, and the computer is getting more and more stuck.

What if the disk space of Win 10 C is getting smaller and smaller? Today, Bian Xiao teaches you the Win 10 slimming coup, mainly to delete some big files that are not very useful, so as to effectively release the system C disk resources and solve the problem of slow computer.

For example, delete the Windows.old file.

If your computer is upgraded from Win 7 or Win 8 to Win 10, and the space on drive C is getting smaller and smaller, it is suggested to delete the file Windows.old, which can free up a lot of space on drive C..

Windows.old file is the backup file of Win7/8 system automatically created when Win7/Win8 system upgrades Win 10, which is convenient for users to roll back to the old system in the future. If you don't plan to reduce the price to Win7/8 system after upgrading Win 10, you can delete this Windows.old file.

The file size of Windows.old is generally above 5GB, and some even reach 10GB. Deleting this file will undoubtedly release the space of drive C to a great extent.

Deleting the windows.old file is very simple, just go to Disk Cleanup and delete it. The specific steps are as follows:

1, first enter this Win 10 computer;

2. Right-click the C disk of the system, and then click Open "Properties";

3. Click "Disk Cleaning" under the Disk General tab, and continue to click "Clean System Files";

3. Finally, check "Previous Windows Installation", and then click "OK" at the bottom to start cleaning.

The third reason why the computer is slow is that there is too much debris and garbage on the computer hard disk.

Temporary files will be generated in the process of installing programs, deleting programs, surfing the Internet, etc. These are junk files. If junk files are not cleaned up, they will not only occupy disk space, but also slow down the running speed of the computer, so they should be cleaned up immediately.

When installing the software, read the installation tips clearly, do not install bundled software, regularly clean up the hard disk garbage and tidy up the hard disk fragments. Replace SSD if necessary, and upgrade or replace larger memory.

If the computer needs a card in the future, you can consider upgrading some hardware. If the gap is too big, just get a new computer.
