About 10 percent of Estonians are still using Windows XP, the operating system that was introduced in 2001 but retired by Microsoft in April.
"Unfortunately all indications are that the people have not moved away from XP. Why? It's more a question for psychologists than for IT people," said the Information System Authority data security expert Anto Veldre on uudised.err.ee.
"Is the problem garden-variety laziness or pirated software people hoarded during the ethics-free development period, which would now have to be replaced?" said Veldre.
Still, in some other countries, XP's market share is as much as 20 percent, and as recently as last spring, one-third of users in Estonia still used it, the expert said.
As to how much XP's security has declined since April when technical support was discontinued, Veldre said it was a matter of conjecture.
But, he said, "data security experts see XP as a dead horse, the corpse is stinking, and they say it's time to move on fast."
Barring a major security hole, people will go on "enjoying the hot summer" and not much will change, offered Veldre.
