I tried the Soluto program, and by following its recommendations, cut my boot time to 1.44 minutes from 2.40 minutes. I removed some applications from the boot sequence, letting them run after the boot was over. I “paused” other applications that I don’t use on a daily basis  for instance, an application that automatically updates Google products. Instead, I’ll wait until the company lets me know when there is an update. (Soluto divides the possible changes in the boot into “no brainers,” “potentially removable apps” and “required, cannot be removed.”)

The company is also working on solutions to other slowdowns, like interruptions while working on Excel or typing in Word when another application suddenly commands Windows resources, causing a timeout. Finding the source of delays is often tricky, Mr. Adler said, because Windows runs on many different computer models; each has its own complement of downloads and devices, all jockeying for attention.

To find the source of each slowdown, Soluto uses a statistical approach, Mr. Dvir said. “Over millions of machines and millions of users, the problems start to repeat themselves,” he said. “There may be 10,000 people with the identical problem, and one of them will find a solution.”

Those millions of users are still in the future, as are their solutions to Windows problems. To acquire those users, Soluto plans to offer free versions of all its products, Mr. Adler said. As it runs on users’ machines, the program will analyze problems and publish solutions. The program won’t reach in and fix the problem directly; the user will have to do that. But if the initial program for boot optimization is any guide, Soluto will be offering suggestions for fixes, letting users know what others have chosen. A premium version that fixes problems automatically will be available for a charge, he said.
