How to modify the registry string value key

Registry modification method.

We can achieve some special functions by modifying the registry, but the registry is very fragile, and if you are not careful, errors will appear. So how do we modify the registry? I summarize it in the following ways:

1.Software Modification (Security).

Modify the registry with special modifying tools, such as MagicSet, TweakUI, WinHacker, etc. In fact, the control panel is one such tool, but the functions are simpler.

2.Indirect modification (relatively safe).

Write the one you want to modify. reg file, and then import it into the registry...The basic format of the reg file is:

regedit4

hkey_local_machine\software\super rabbit\magicset]

="super rabbit magic set for windows 98 "

a"=dword:00000001

b"=hex:02,05,00,00

hkey_local_machine\software\scc\quickviewer]

The first line is "regedit4" and must be capitalized.

The second line is blank.

The third line uses the parenthetical sub-key branch, where the hkey local machine software super rabbit magicset is a sub-key branch.

Clause. Lines 4, 5, and 6 are the settings under this subkey. where @ is in the right pane of the registry"Default"Key.

The following is similar. This has the advantage of avoiding erroneous writes or deletes, but requires the user to understand the internal structure of the registry. The format of the reg file.

3.Direct modification (the least secure, but most straightforward and effective).

It is to modify the key-value data items of the registry directly through the registry, which will avoid leaving garbage in the registry (although they are all small, but more and more will slow down the system), but the user is required to have a certain knowledge of the registry, be familiar with the internal structure of the registry and be cautious.

Helpless recruits.

Since you didn't mention the key name, I'll assume that the key name is path and the key type is string uses

registry;

varreg

tregistry;

beginreg:=

trywith

regdobegin

rootkey

hkey_local_machine;

ifopenkey('softwaredelphi',false)then

ifreadstring('path')

'thenbeginshowmessage('The key value does not need to be modified');

exit;endelse

writestring('path','')else

showmessage('Failed to open the item, check if the item exists');

end;finally

end;

Start Menu - Run - Type "regedit", open the registry and find this key: hkey local machine software computer

artworks/thething/

。。And then it's all the same!

Start - Run - Enter regedit enter.

Find the one you want to modify in the open registry.

Modify it to what you need.

Open the registry, find the item you want to change, double-click to open and enter the value you want to modify!

These key-value item data can be divided into three types:

1.String value.

In the registry, string values are common, so how do we modify the registry? I summarize it in the following ways:

1.Software Modification (Security).

Start->Run-> input"regedit",You can enter the registry.,It's like a resource manager.,Find it one level at a time.,You can modify it on the right.。

It's better to back it up first.,It's not a joke to change it.。

For example, I'm going to start a notepad (c:) when I turn it on.

Then the Advanced Registry (Start-Run.

Locate in order:

Then in the space on the right, right-click New -String.

The "New value" appears

Double-click on the "New Value 1" in the "Numeric Data" field, and enter: c: Close the registry So that every time you turn on your computer, you'll run this notepad!

What do you need to do?

Changing the registry can do a lot of things!

Start running.

regedit

Find the right-click Modify to change the key value.

Find that key, double-click, and you'll be directed to a dialog box, and then change it to the value you need.

Most of the modifications made to the registry are modifications to the keys that already have key-value entries. The registry example makes this work very simple, the basic method is to search in the keybox window on the left until you find the key to which the key value you want to modify belongs. Double-clicking a key-value item will bring up a modification dialog box, depending on the data type of the selected key-value item"String value. ","Binary values"with"dword value"dialog box, in the dialog box you need something, finally click "OK", and everything will be done in no time!

Enter on the run.

But the reminder is that system optimization, to be honest, is not good for the system, people who really understand computers and love computers will not pursue computers fast.
