3. Found process name in started as SVCHOST process in Windows XP
If you are meet issue with like me to fond process with much CPU or Memory usage. But when you try to determine the process name it appears like "svcshost". And also in tasklist you found more than one with that name. But only one with that name using much resources. There is some processes are running under same name "svchost". It is like a container for group of process. Even more they could be a different executing files.
So how to determine the name of service in "svchost" container, using much CPU or Memory?
In microsoft.com you search for "how to find process name by pid" and you will found this KB314056
In knowladge is information about command in CMD. This commant show list of process and their PID and their file or program name. So here is the example of what program will show.
As you can see there is  many process under "svchost" name. So this could help you to determine the process wich CPU or memory usage is much.

4. How to change user password in Command Prompt (cmd)
This could help you to change even Administror's password of computer. But your user is restricted to do this you will not be able to use it.

To change a user's password at the command prompt, log on as an administrator and type:
net user user_name * /domain
When you are prompted to type a password for the user, type the new password, not the existing password. After you type the new password, the system prompts you to retype the password to confirm. The password is now changed.

Alternatively, you can type the following command:
net user user_name  new_password
When you do so, the password changes without prompting you again. This command also enables you to change passwords in a batch file.

Non-administrators receive a "System error 5 has occurred. Access is denied" error message when they attempt to change the password.

Here is more net user commands

Start from Windows Vista/7 DVD to launch a command prompt, then change the security settings for C. Microsoft provides this command prompt command to give everyone access:

7. Windows prefetch cache

8. How to make archive folder without any program in Windows
Do you ever wonder how to compress (zip/rar) your Windows files and folder without WinZip or WinRar. This could be done since Windows XP (probable even since Windows 2000). So what I am talking abaout.
I am prety sure that everyone who use Windows as operation system, have ever uncompress some archive files, which was compressed. And as you remember it appears a menu in left panel in Windows Explorer extract options.
In Windows since XP version has integrated compression option for files and folders. But does it can be used in reverse way? It can be used in reverse, but where is the options?
By opening the content menu by right click, in options you find the sub-menu "Sent to". This menu will give you some options "Compressed (zipped) folder", "Desktop (create shortcut)", "Documents", "Fax recipient", "Mail recipient", "Skype". Any of these option give you options of listed features to send data to it.
  
I have noticed one very peculiar issue - my Desktop Windows Manager(aka Windows Aero) suddenly terminated by itself a while ago, and my theme became Windows 7 Basic's. It was very sudden and without warning. I've check the Event log and I found this 2 entry
Entry 1:
"A request to disable the Desktop Window Manager was made by process (Windows System Assessment Tool)"
Source: Desktop Window Manager
Event ID: 9010

Entry 2:
"The Desktop Window Manager was unable to start because composition was disabled by a running application"
Souce: Desktop Window Manager
Event ID: 9013

Found a solution.  
In the start bar search type "Task Scheduler" 
This will bring up the Task Scheduler App.
On the left click the Task Scheduler library
next click microsoft
-----> Maintenance
--------------------------> WinSAT
Right click on winSAT and go into properties and delete the trigger.
now it wont trigger the Performance test..


How to delete pagfile.sys on SSD

If you really want to delete it, first disable it. You can do this from advanced performance options in System Properties.
You can get there by running sysdm.cpl, clicking the Adanced tab and clicking the Settings... button for Performance. Then clicking the Advanced tab in the new Performance Options window and clicking theChange... button.
  • Uncheck Automatically manage paging file size for all drives
  • Set all drives to No paging file
  • Click OK until Windows suggests restarting
After restarting you can safely delete pagefile.sys.
However, I don't think you should ever disable the pagefile, especially if you have an SSD; as an SSD will only speed it up.
Windows always uses virtual memory, and although RAM pools are large enough these days for most people to avoid problems, there's no real benefit in making Windows unstable by limiting that space to the size of your RAM rather than the size of what Windows may need.

Change Windows (7) loggin screen.

Make your new loggin screen wallpaper and go to C:\Windows\System32\oobe\info. Then replace the existing one.


How to stop Scan Disk (check disk) at startup Windows 7/8/10
