Five notes on the Windows operating system

About the cleanup of the Windows system, although there are many online methods, in fact, simply do the following.
1, regular hard disk
Severe hard disk fragmentation will greatly reduce your computer's response speed. So you need to clean the disk regularly. Disk cleaning is very simple. First click “Start”, then point to <;All Programs>,"Accessories",“System Tools”, then click “Disk Cleanup”. If you have multiple drives, you will be prompted to specify which drive to clean.
2, regularly clean up the Windows registry
to prevent registry garbage using such tools as Registry Cleaner. Do not use Outlook Express, which stores spam filters in the registry. There are many online cleaning tools on the Internet. I recommend two registry cleaners and RegClear. But one thing, you must back up the registry before cleaning.
3. Try not to use "admin" account login
Do not always use "admin" account login, especially when copying files from external to your PC. If you just log in with a normal privileged user, most malware won't succeed. Creating a limited account is easy, so you don't need to introduce it one by one. You can create it under Control Panel's "User Account".
4, be careful what you install
Many "free" tools with spyware, it is difficult to kill. Use the name of the software you want to install and "spyware" as a keyword to search online. If you find any spyware reports, do not install them.
5, keep anti-virus and anti-spyware updates
Malware often spam in the registry, will also start unnecessary Windows services, do a lot of things to reduce system performance, and even cause the system to work at all.
