Windows 8.1 may fix Microsoft's dot-zero release but it may not fix the PC market.
"May results reflect deteriorating conditions rather than improvement and the market will probably fall short of projections," said Loren Loverde, an IDC analyst in a statement, referring to May regional PC shipments.
"The results for May are behind pace for achieving the projected [second quarter 2013] growth rate," Loverde added.
Currently IDC expects total annual growth of negative 7.8 percent for 2013.
And IDC appears to be preparing itself for possible future growth revisions. While saying on the one hand that it expects an "improvement" in the second half, in the same sentence IDC states that the "market will likely remain cautious about the second half of 2013."
Earlier this month, Citi Research cut its 2013 PC year-to-year growth to negative 10 percent from negative 4 percent growth, according to a note to investors.
"The Citi global technology team is revising down its 2013 PC growth estimate to -10% y/y (from -4%) based on further sub-seasonal demand" in the first quarter and slowing notebook production, the note said.
Citi also included a zinger about Windows 8.1 and Intel's new Haswell chip.
Despite investor optimism on a resumption of year-to-year growth in the second half of 2013, "we do not expect [PC] units to grow" due to a "softening in PC end-demand" and "muted benefit from Haswell and Windows Blue [Windows 8.1]."
