To unpack the installation, use Universal Extractor, but the latest version, not all hotfiksy from MS decompresses correctly and must use other methods. One option is to add to the context menu command to Unpack HotFix.
1) copy the code into any text editor (e.g. Notepad).
2) press CTRL + S to save the file with any name and .reg
3) if you choose the type of files: text files, the file name in quotation marks to be sure. (For example: “demo.reg”)
4) if you choose the Save as type: all files, the file name in quotation marks do not have to borrow.
To add this item to the context menu, create the following .reg file:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\exefile\shell\Unpack HotFix\command]
@="\"%1\" /X:\"%1_unpacked\""
For example, when unpacking Windows6.1-KB917607-x64.exe, get folder Windows6.1-KB917607-x 64: exe_unpacked with files.
Minus one – command Unpack.exe HotFix is embedded into the context menu of all .exe files, not only files from Microsoft.
To remove this item from the context menu, create the following .reg file:
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\exefile\shell\Unpack HotFix]
[-HKEY_CLASSES_ROOT\exefile\shell\Unpack HotFix\command]
@=-

How to add a context menu for folders command to delete the contents of a folder without deleting the folder? You can build up a click “Delete contents of folders” on the shortcut menu, and you will only have to choose it. You don’t have to open a folder, select all files and press the Delete key.
Option 1.
1) start Registry Editor: Win + R-> regedit-> Ok
2) Open the registry branch HKEY_CLASSES_ROOT\Directory\shell
3) crate section DeleteFolderContent
4) Create the string MUIVerb with value Delete folder contents.
5) in section DeleteFolderContent, create the subkey command
6) change the Default command to the following:
cmd /c "cd /d %1 && del /s /f /q *.*"

Option 2.

1) copy the code into any text editor (e.g. Notepad).
2) press CTRL + S to save the file with any name and .reg
3) If you choose the type of files: text files, the file name in quotation marks to be sure. (For example: “DeleteFolderContent.reg”)

For some unknown reason, Microsoft developers decided not to include in the Windows Explorer context menu items Copy To and Move To. Using them, you can easily copy or move a file or folder. To do this, simply select the desired location in the dialog box. To add these commands to the context menu, simply create the corresponding settings in the registry.
Option 1
1) start Registry Editor (click the button Start, type regedit in the Search bar and press Enter).
2) open the registry branch HKEY_CLASSES_ROOT\AllFilesystemObjects\shellex\ContextMenuHandlers
3) create a partition with the following name (including the curly brackets):
To add a context menu item to Copy To
{C2FBB630-2971-11D1-A18C-00C04FD75D13}
To add a context menu item Move To
{C2FBB631-2971-11D1-A18C-00C04FD75D13}
4) press Enter
5) Restart Windows Explorer or log of/log on in the system, and these items will appear on the shortcut menu.
Option 2
1) copy the code into any text editor (e.g. Notepad).
2) press CTRL + S to save the file with any name and .reg
3) if you choose the type of files: text files, the file name in quotation marks to be sure. (For example: “DeleteFolderContent.reg”)
4) if you choose the Save as type: all files, the file name in quotation marks do not have to borrow.

If you often use any program, in addition to adding it to an icon on the desktop, you can also add it to your Computer. Because copy directly or create a shortcut in this folder, I suggest you a solution as possible.

1) copy this code into any text editor (e.g. Notepad):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{GUID}]
@="Name of a folder or program"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{GUID}\DefaultIcon]
@="Path to icon"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{GUID}\Shell]
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{GUID}\Shell\Open]
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{GUID}\Shell\Open\Command]
@="Path to a folder or program"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer\NameSpace\{GUID}]
2) download Microsoft Exchange Server GUID Generator
3) extract the archive and run the program (GUIDGEN.EXE)
4) click on the value of the Registry Format
5) click New GUID, and the program will generate a new GUID
6) click on the Copy, and the program will copy it to the Clipboard
7) Insert instead of {GUID} generated by GUID.
You now have in place of {GUID}, digital ID, for example: {FF4A6226-409e-C00B-88A6-6C401C52BD98}
8) replace the values of “Name of a folder or program”, “Path to icon” and “Path to a folder or program” for you.
Attention! In path to the icon and the file object must be a double slash.
For example, if the path to the program: C:\MyProgram\MyProgram.exe, you must specify it as: C:\\MyProgram\\MyProgram.exe
Because, most often icon program built into the program itself, the value of “Path to icon” and “Path to a folder or program” can match.
9) when adding a folder shortcut, edit the “Path to icon” on %SystemRoot%\\system32\\SHELL32.dll, 4
A value of “Path to a folder or program” on the explorer /n, /e, C:\\Your folder
10) after specifying all the values, press CTRL + S to save the file with any name and .reg
10.1) If you choose the type of files: text files, the file name in quotation marks to be sure. (For example: “GUID.reg”)
10.2) If you choose the Save as type: all files, the file name in quotation marks do not have to borrow.
11) Apply the resulting .reg file.

Eventually you will get the same effect that was mentioned in the tip 3 of section “Registry Tweaks – Additional functionality”.

If you often have to work with an ocx files or dll files that require registration in the registry by using Regsvr32.exe, it will be much easier to make a corresponding entry in the register, each time you use the command line for each file.

Start Registry Editor (Win + R-> regedit-> Ok)

Create the item “Registration” in the menu of a DLL or an OCX file.

1) in the branches of the registry HKEY_CLASSES_ROOT\ocxfile\Shell and HKEY_CLASSES_ROOT\dllfile\Shell
2) create a Register key, and the subkey command
3) in the HKEY_CLASSES_ROOT\ocxfile\Shell\Registration\command and
HKEY_CLASSES_ROOT\dllfile\Shell\Registration\command set string parameter Default value: regsvr32.exe “%1″

Create the item “Cancel registration” in the menu of a DLL or an OCX file.

1) in the branches of the registry HKEY_CLASSES_ROOT\ocxfile\Shell and HKEY_CLASSES_ROOT\dllfile\Shell
2) create a Cancel registration key and the subkey command
3) in the HKEY_CLASSES_ROOT\ocxfile\Shell\Cancel registration\command and HKEY_CLASSES_ROOT\dllfile\Shell\Cancel registration\command set string parameter Default value: regsvr32.exe /u “%1″
Now when you right-click on the DLL or OCX file that shows items in the menu “Registration” and “Cancel registration”.

You can increase the number of folders for which Windows will remember the settings form.

1) start Registry Editor (Win + R-> regedit-> Ok)
2) open HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell
3) create a DWORD BagMRU Size and assign a decimal value, for example, 20000.

Also you can create a .reg file.

1) copy the code into any text editor (e.g. Notepad).
2) press CTRL + S to save the file with any name and .reg
3) If you choose the type of files: text files, the file name in quotation marks to be sure. (For example: “folder_cache.reg”)
4) If you choose the save as type: all files, the file name in quotation marks do not have to borrow.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell]
"BagMRU Size"=dword:00004e20

For quick access to needed you desktop options, you can add it to the context menu of the desktop. To do so, you need to create and apply the .reg file to read.

Add item “Run” to invoke the same dialog box menu.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\Background\shell\Run]
"Icon"="%SystemRoot%\System32\imageres.dll,-100"
"MUIVerb"="@%SystemRoot%\explorer.exe,-7023"
<br />
[HKEY_CLASSES_ROOT\Directory\Background\shell\Run\command]
@="%SystemRoot%\system32\rundll32.exe shell32.dll,#61"

Add an item “Search” to invoke the same window.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers\Search]
@="{2559a1f0-21d7-11d4-bdaf-00c04f60b9f0}"

Add item “Empty Recycle Bin”.
Windows Registry Editor Version 5.00

Ready-made .reg files to add and delete you can download here: options in the context menu.zip

Add links to your favorite programs to the context menu of your Windows desktop is two parts:

Part 1. To create cascading menus on the shortcut and add labels.
Part 2. Adding functionality shortcuts by their registration.

Part 1. Creating context menus and adding shortcuts.
1) start Registry Editor (Win + R-> regedit-> Ok)
2) open the branch HKEY_CLASSES_ROOT\DesktopBackground\Shell
3) create a new key in this thread. Right-click on “Shell” key and select “New-> key”. (e.g. Menu1)
4) select the newly created section “Menu1″ and in the right pane, create a 4 string parameter:
Icon
Position
MUIVerb
SubCommands

Icon – set this option, you specify the path to the icon menu.
Position – this parameter defines the position of a cascading menu shortcut. By default it is the middle of the context menu, but you can choose to use the Top or Bottom.
MUIVerb – cascade menu name that will appear on the shortcut menu. For example, “my programs”, “browsers”, etc.
SubCommands – contains a list of commands, separated by a semicolon (;). these commands will be shown on the cascading menu. you cannot directly add a shortcut to this application first on this list you need to give the team name, and then register it according to the instructions in part two of this article.

Suppose that you have already created a cascading menu “browsers”, and now you want to add shortcuts to Internet Explorer and Mozilla Firefox. In this case, you need to set SubCommands:
firefox;iexplore
Settings Icon and Position you may not create, but MUIVerb and SubCommands — are required.

Part 2. Adding functionality shortcuts by their registration.
Once you have added shortcuts to programs in cascade menu, you will need to register them as follows:

1) open the branch HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\Shell
2) create a for each of the commands listed earlier in the string parameter SubCommands, own the homonymous section. In our example we used two commands: firefox and iexplore, so we need to create two partitions with the same names.
3) select the created partition and in the right pane of Registry Editor, set the parameter Default name that you want to see the cascading menu. For example, type here Internet Explorer (iexplore partition) or Mozilla Firefox (firefox partition).
4) If you want to add a shortcut icon, create a new string parameter named Icon, and set its value to the path to the .EXE file, application or any other icon.
For example, to show the icon of Internet Explorer, you should set the parameter Icon value C:\Program Files\Internet Explorer\iexplore.exe
5) in each of the newly created partition, create a new key and name it command.
Select it and in the right pane, select a Default path to the .exe file that has the necessary software. For example, if a shortcut to open Internet Explorer, you should be set to C:\Program Files\Internet Explorer\iexplore.exe

Ready the .reg file context menu desktop (from the described example):
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\DesktopBackground\Shell\Menu1]
"MUIVerb"="Browsers"
"SubCommands"="firefox;iexplore"
"Icon"="C:\\Program Files\\Internet Explorer\\iexplore.exe"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\firefox]
@="Mozilla Firefox"
"Icon"="C:\\Program Files\\Mozilla Firefox\\firefox.exe"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\firefox\command]
@="C:\\Program Files\\Mozilla Firefox\\firefox.exe"
<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\iexplore]
@="Internet Explorer"

<br />
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\iexplore\command]
@="C:\\Program Files\\Internet Explorer\\iexplore.exe"
Note: If you want to remove generated cascading menu, simply delete your keys from the registry.

1) start Registry Editor (Win + R-> regedit-> Ok)
2) open the branch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
3) locate the option WaitToKillServiceTimeout
4) change its value to you. This option is responsible for the delay before shutting down.
The default value (20000) = 20 seconds, but you can install it, much less the nominal value (minimum 100), and the system will be much faster.
Recommended values (2000-5000) = 2-5 seconds. (not recommended, otherwise the system will understand adequately the lack of responses from services, startup and shutdown of the “wrong” time, for example when they retain their previous settings).

If you wish to change the delay before displaying a pop-up menu in the start menu, do the following:

1) start Registry Editor: Start – > Run->regedit->OK (or Win + R-> regedit-> OK)
2) go to HKEY_CURRENT_USER\Control Panel\Desktop
3) create (or modify) option MenuShowDelay
4) to create, right-click, select New, and then click DWORD (32-bit).
5) to modify, right-click, select Modify option
6) Select the desired value from 1 through 4000, meaning a delay in milliseconds to display the pop-up menu in the start menu.
7) Close regedit and reboot the system.

What is a notification system tray, knows every user of Windows 7. Once it pops up in life and on the screen of a personal computer.
