Citrix picked its new CEO yesterday, naming former Microsoft executive Kirill Tatarinov to the post.

Tatarinov, who will start on Jan. 25, replaces longtime CEO Mark Templeton. Templeton had announced in July that he was going to retire, but then he resigned abruptly in October, with executive chairman Robert Calderoni taking his place on an interim basis.

Citrix is one of the companies that's been dogged by Elliott Management. The activist hedge fund, which gained a seat on Citrix's board last summer, has prodded Citrix into trimming its staff and portfolio. In November, Citrix announced it would spin off the GoTo product suite and lay off roughly 1,000 of its more than 10,000 employees.

Tatarinov spent 13 years at Microsoft, most recently as executive vice president of the Business Solutions Division. He was formerly CEO of BMC.

Citrix announced the move after markets closed yesterday. Its stock is up less than 1 percent at $67 this morning.
