Microsoft has been modifying files in the Windows Vista and Windows XP operating systems without the knowledge or consent of the users that have acquired the products in good faith. The Redmond company's incognito updates served both to XP and to Vista are an integer part of a long time practice over at Microsoft, targeting Windows Update and are as old as the updating infrastructure that the company has built for its platforms. Nate Clinton, Windows Update Program Manager initially admitted the stealthy updates to Windows but argued that they only benefited
the end users and that they caused no harm whatsoever.

Well, Scott Dunn, from Windows Secrets, the editor that originally broke the news about Microsoft's silent Windows updating practices, proved the company wrong. Copies of Windows XP repaired via the options on the disc, prior to the deployment of the secret patches, failed to install all additional updates. Clinton subsequently acknowledged the validity of the problem.

"When an XP repair CD is used, it replaces all system files (including Windows Update) on your machine with older versions of those files and restores the registry. However, the latest version of Windows Update includes wups2.dll that was not originally present in Windows XP. Therefore, after the repair install of the OS, wups2.dll remains on the system but its registry entries are missing. This mismatch causes updates to fail installation", Clinton explained.

The sole explanation that Microsoft offered for the silent patches introduced to Windows Update in Windows XP and Vista was nothing more than routine maintenance of the service. The company explained that without the updates WU would fail to perform successful identification, download and deployment of patches served for XP and Vista. Clinton additionally disclosed a modality for users of Windows XP affected by the issue to regain functionality of Windows Update:

"1. Stop the Automatic Updates service. To do this, follow these steps:
a. Click Start, click Run, type cmd, and then click OK.
b. At the command prompt, type the following commands, and then press ENTER after each command: net stop wuauserv and exit.

2. Register the file that is used by Windows Update and Microsoft Update. To do this, follow these steps:
a. Click Start, click Run, type cmd, and then click OK.
b. At the command prompt, type the following command, press ENTER after the command, and then click OK when you receive a verification message:
regsvr32 %windir%system32wups2.dll
Note: for x64 machines regsvr32 %windir%syswow64wups2.dll

3. Start the Automatic Updates service. To do this, follow these steps:
a. Click Start, click Run, type cmd, and then click OK.
b. At the command prompt, type the following commands, and then press ENTER after each command: net start wuauserv and exit."

People throughout Asia have enjoyed foods and beverages containing caffeine for thousands of years. Whether green, black or oolong, tea has been savoured in Asia for almost 5,000 years. Coffee, a relative newcomer discovered some 1,000 years ago, continues to bring people together in the coffee houses and cybercafes springing up across the region. Over the last hundred years, cola drinks, ready-to-drink tea and coffee beverages and a new crop of "energy drinks" have steadily gained in popularity.

All these beverages have a common ingredient - caffeine. Although products containing caffeine have been enjoyed all over the world for centuries, there are still many misperceptions about this common food component. Food Facts Asia looks at some of the more common myths regarding caffeine.

MYTH: Caffeine's effects are addictive.

FACT: People often say they are "addicted" to caffeine in much the same way they say they are "addicted" to shopping, working or television. The term "addiction" actually refers to a strong dependence on a drug characterised by severe withdrawal symptoms, tolerance to a given dose and the loss of control or the need to consume more and more of the substance at any cost. Addicts tend to exhibit anti-social behaviour or even commit crimes to perpetuate the abuse. Consumers of caffeine-containing beverages do not fall into this category. The Diagnostic and Statistical Manual for Mental Disorders (1994), a document that characterises various addictions, does not list caffeine as a substance that causes addiction. According to the World Health Organization, "There is no evidence whatsoever that caffeine use has even remotely comparable physical and social consequences which are associated with serious drugs of abuse."

MYTH: Pregnant women should avoid caffeine.

FACT: Just as with nearly everything else they do, pregnant women can take caffeine in moderation. Many women find they experience taste changes during pregnancy and cannot drink tea or coffee. For those who continue to enjoy their tea and coffee, most physicians and researchers agree that moderate amounts of coffee daily will have no adverse effects on the outcome of the pregnancy or the infant's health.

MYTH: Caffeine is a risk factor for osteoporosis.

FACT: The established risk factors for osteoporosis are insufficient dietary calcium and vitamin D, high protein diets, smoking, the onset of menopause, low oestrogen levels, low body weight and a lack of physical activity. Several well-controlled studies have concluded that consuming moderate amounts of caffeine does not increase the risk of developing osteoporosis. A 1994 National Institute of Health Consensus Statement on optimal bone health does not list caffeine amongst the risk factors which modify calcium balance and influence bone mass. A study by Penn State Medical School found that lifetime consumption of caffeine (up to 800 mg daily or the equivalent of 6-7 cups of coffee a day) had no effect on bone density in 188 post-menopausal women.

Nevertheless, caffeine does cause a small amount of calcium to be lost in the urine – about the amount in one to two tablespoons of milk per cup of tea or coffee. For this reason, nutritionists recommend that women take their coffee with added milk, drink one extra glass of milk daily or take a calcium supplement if they are heavy coffee drinkers (over 5 cups of coffee daily).

MYTH: Caffeine increases the risk of heart disease.

FACT: Despite previous controversy on the subject, scientists now agree that regular caffeine use has little or no effect on blood pressure, cholesterol levels or risk of heart disease.

Studies show that while first-time caffeine use can cause a slight increase in blood pressure (similar to that experienced when walking up stairs), the changes are minimal and disappear with regular use.

It has also been found that only boiled, unfiltered coffee, such as that taken in some Scandinavian countries, elevates cholesterol. It seems the oils in the coffee that are not filtered out are responsible for this effect, not the coffee or caffeine. Consumption of caffeine-containing beverages does not typically affect cholesterol levels.

MYTH: Caffeine causes cancer.

FACT: Substantial scientific evidence demonstrates that caffeine is not a risk factor for cancer. A number of human epidemiological studies have examined the risk of developing cancer at different locations in the body. Two studies of large numbers of people in Norway and Hawaii found no relationship between regular coffee consumption and cancer risk. Two projects conducted on caffeine - one in Japan and the other in Germany - demonstrated no link between caffeine consumption and the incidence of tumours in test animals. This confirms the position of the American Cancer Society, that states, "Available information does not suggest a recommendation against the moderate use of coffee. There is no indication that caffeine, a natural component of both coffee and tea, is a risk factor in human cancer."

MYTH: Caffeine adversely affects the health of children.

FACT: Children generally consume much less caffeine than adults do, since soft drinks and tea are their primary sources of caffeine. Children generally have the same ability to process caffeine as adults. Studies have shown that foods and drinks containing caffeine, when taken in moderate amounts, have no detectable effects on activity levels or attention spans in children.

MYTH: Caffeine has no health benefits.

FACT: Recent research has found some surprising health benefits associated with caffeine consumption. Many caffeine-containing beverages, most notably tea and more recently coffee, have been found to contain antioxidants. Antioxidants may have health benefits in terms of heart health and cancer prevention.

Caffeine is well recognised as increasing both alertness levels and attention spans. A cup of coffee or tea is often recommended to counter sleepiness, especially for those driving long distances and many people resort to an afternoon "cuppa" to get back on top of their workload.

Recent reports suggest that caffeine may be useful in treating allergic reactions due to its ability to reduce the concentration of histamines, the typical body response to an allergy-causing substance. More research is needed in this area before conclusions can be drawn. Caffeine has long been known to help many people suffering from asthma.

There is also evidence to suggest that caffeine may reduce the risk of kidney stones.

Tea is good for you. What are the scientifically recognized benefits of tea? The following is a brief synopsis of the latest findings.

AGING
If you are the type to fret over the appearance of wrinkles, age spots and other signs of growing old, oolong tea may be the answer to your worries. In a recent experiment carried out jointly by researchers from the US, Taiwan and Japan, mice which were fed tea displayed fewer signs of aging than mice that were fed water. The Straits Times, Sept. 24, 01

ALLERGIES
The wonder cup just got even more wonderful. Green tea, rich in antioxidant treasures that protect against heart disease and cancer, now shows promise as an allergy fighter. In laboratory tests, Japanese researchers have found that the antioxidants in green tea, block the biochemical process involved in producing an allergic response. Green tea may be useful against a wide range of sneeze-starting allergens, including pollen, pet dander, and dust. Prevention, April 2003

ARTHRITIS
Green tea catechins are chondroprotective and consumption of green tea may be prophylactic for arthritis and may benefit the arthritis patient by reducing inflammation and slowing cartilage breakdown. The Journal of Nutrition, Mar 2002

Green tea may be useful in controlling inflammation from injury or diseases such as arthritis. Boston Globe, April 26, 99

BONE STRENGTH
Tea flavonoids may be bone builders. A report in this week's Archives of Internal Medicine looked at about 500 Chinese men and women who regularly drank black, green, or oolong tea for more than 10 years. Compared with nonhabitual tea drinkers, tea regulars had higher bone mineral densities, even after exercise and calcium-which strengthen bones-were taken into account. U.S. News & World Report, May 20, 2002

CANCER
"Tea is one of the single best cancer fighters you can put in your body," according to Mitchell Gaynor, MD, director of medical oncology at the world-renowned Strong Cancer Prevention Center in New York City and co-author of Dr. Gaynor's Cancer Prevention Program. The latest tea discovery? Strong evidence that both green and black tea can fight cancer-at least in the test tube-though green tea holds a slight edge. In a new study, both teas kept healthy cells from turning malignant after exposure to cancer-causing compounds. Prevention, May 2000

People who drink about 4 cups of green tea a day seem to get less cancer. Now we may know why. In recent test-tube studies, a compound called EGCG, a powerful antioxidant in tea, inhibited an enzyme that cancer cells need in order to grow. The cancer cells that couldn't grow big enough to divide self-destructed. It would take about 4 cups of green tea a day to get the blood levels of EGCG that inhibited cancer in the study. Black tea also contains EGCG, but at much lower concentrations. Prevention, Aug 1999

CHOLESTEROL
Tea can lower 'bad' cholesterol levels. Researchers at the Beltsville Human Nutrition Research Center in Beltsville, Maryland, asked test subjects to eat low-fat, low-calorie prepared meals and drink five cups of caffeinated tea or caffeinated and non-caffeinated placebos that mimicked the look of tea. Levels of low-density lipoprotein (LDL) cholesterol dropped 10 percent among the test subjects who drank tea. Vegetarian Times, Jan 2003

HEART DISEASE
Drinking black tea may lower the risk of heart disease because it prevents blood from clumping and forming clots. In a recent study, researchers found that while drinking black tea, the participants had lower levels of the blood protein associated with coagulation. Better Nutrition, Jan 2002

Better to be deprived of food for three days than tea for one,� says a Chinese proverb. Research is showing it may just be true. Dr. Kenneth Mukamal of Boston's Beth Israel Deaconess Medical Center reported that out of 1,900 heart-attack patients, those who drank two or more cups a day reduced their risks of dying over the next 3.8 years by 44 percent. Newsweek, May 20, 2002

WEIGHT LOSS
Trying to lose weight? Reach for a cup of green tea instead of a diet beverage. Compared to the placebo and caffeine, green tea extract consumption produced a significant 4% increase in 24-hour energy expenditure. If you consume 2,000 calories per day and don't gain or lose weight (you're in energy balance), an increase of 4% would translate roughly into an 80-calorie daily difference. Over a year, this could result in 89 pounds of weight loss. American Journal of Clinical Nutrition, Nov 1999

Recent evidence shows that in the battle of fat loss, green tea may be superior to plain caffeine. According to a new study, green tea appears to accelerate calorie burning - including fat calories. Researchers suggest compounds in green tea called flavonoids may change how the body uses a hormone called norepinephrine, which then speeds the rate calories are burned.
