Enable Flash Only on Specific Sites in Internet Explorer

People hate Flash for various reasons: browser crashes, vulnerability in the add-on that permits an attacker or attacking website to install malware on the PC, lack of support on certain mobile devices or self-playing animated advertisement. When you install an extension such as Adobe Flash in a browser, it is automatically permitted to run on all websites. But one feature that is unique to Internet Explorer 8 and 9 is that it allows the user to restrict the use of add-ons on specific Web sites.

Internet Explorer 8 and 9 allows greater control of where and under what context ActiveX controls and add-ons can run. Add-ons can be managed through the new Manage Add-ons Manager implemented in IE8 and improved in IE9.

To open Add-ons Manager, click on the Tools menu (the gear icon in the toolbar in IE9) and then select Add-ons Manager.

Double click on Shockwave Flash Object or right-click on it and choose ‘More Information’. If you can’t see Shockwave Flash Object in the list, select “All add-ons” from the Show drop-down menu as shown below.

manage-addon-ie

By default, Flash ActiveX control is set to run on all sites, so you will find a * under the approved sites list. Click the ‘Remove all sites’ button to delete the * and close the dialog. This prevents Flash ActiveX control from running for all sites.

flash-information

Browse to the website for which you want to enable Flash animations. You’ll see an information bar asking for your permission to run the Active-X control. Click the information bar and choose Run Add-on.

run-addon

Do this on all websites that you want to whitelist. Check the Shockwave Flash Object information dialog box again, and all approved sites should be reflected there.

flash-approved-sites

The white-list data is stored in the following registry location:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Ext \ Stats \ {D27CDB6E-AE6D-11CF-96B8-444553540000} \ iexplore \ AllowedDomains

You can export this key as a .REG file for the purpose of backing up the approved sites list or for deploying it on another computer.

How to Record CPU and Memory Usage Over Time in Windows?

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph. You get a small time-window, about 30 seconds or so, depending on how large the viewing area is.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website.

So, here is how you can do that.
