After upgrading and installing Win10 official version, the speed is slow. C disk memory is obviously smaller, what should I do?

Are you slow down after the computer system upgrade? Even the boot is slow for a long time? Even when you open the C drive, the memory actually takes up a lot? So how to solve this situation? Let's do it with me below.

1. Clean up the useless files of the C drive. Find the C drive & mdash;—properties ——click “Disk Cleanup>

2, then the cleanup box will appear. At this time, continue to select — — “ clean up the system file & rdquo;, because the old version before the upgrade belongs to the system file, still occupy the C disk memory after the upgrade

3, here is the point. Note that you should check ——“The previous windows installation" (this file probably has 20G, it can be imagined that it affects the speed of the computer), the memory state after I cleaned up
< Br>

4, then you can check ——windows update——windows install temporary files —— recycle bin, wait for some useless folders, then select ——delete files

5, this time waiting for cleaning on the line

6, change the temporary file storage of IE browser, open IE browser & mdash; — tool & ldquo; internet option & rdquo; Br>

7. In the regular —— click on the browsing history & ldquo; settings & rdquo;

8, the current location is the C drive. So select ——“move folder”change the temporary file storage location (select the other drive letter root directory). Finally, click OK to complete, and the C drive problem is solved. You will find that the system is running much faster.
