Microsoft Internet Explorer stores every webpage you visit in a temporary cache file on your hard drive. This allows the page to open more quickly each time you revisit the address. A setting in Internet Explorer controls the behaviour of this function, determining how often the browser checks for a new version of a stored page. You can change this setting in the registry using the Windows Registry Editor or the Command Prompt.

Press the "Windows" and "R" keys simultaneously. This opens the "Run" box.
Type "Regedit" into the "Open" field and click the "OK" button. This opens the Windows Registry Editor.
Navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" in the left-hand pane.
Right-click the "Internet Settings" folder and click "New DWORD." This creates a "New Value #1" entry in the right-hand pane.
Right-click "New Value #1" and click "Rename." Change the name of the value to "SyncMode5."
Right-Click "SyncMode5" and click "Modify."
Type a new value for the function into the "Value Data" box. Type "0" if you never want Internet Explorer to check for a newer version. Use "2" if you want Internet Explorer to check for a newer version every time you start the browser. Enter "3" if you want Internet Explorer to check every time you revisit the page. Type in "4" if you want Internet Explorer to automatically determine when to check for a newer version (this is the default value). Click "OK."
Close the Registry Editor and restart Internet Explorer.
Click "Start" and type "CMD" into the "Search" box.
Right-click "CMD" from the list of search results and click "Run as Administrator." Click the "Yes" button in the "User Account Control" dialogue box.
Type or paste "Reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v SyncMode5 /t REG_DWORD /d 4 /f > NUL" into the Command Prompt and press "Enter." Replace the "4," which tells Internet Explorer to automatically decide when to check for a new version, with "0" if you never want Internet Explorer to check for a newer version. Use "2" if you want Internet Explorer to check for a newer version every time you start the browser. Set the value to "3" if you want Internet Explorer to check every time you revisit the page.
Close the Command Prompt and restart Internet Explorer.
Tips and warnings
- Creating ".CMD" scripts using the "Reg add" command to quickly switch between different modes. This is particularly useful for rooted Intranets that rarely need updating (see Resources).
- Automate the process by using the task scheduler to switch the setting with a script every time a scheduled update runs (see Resources).
- Clear the temporary cache each time you change this behaviour to ensure that the client will always receive a clean copy of the new resources.
