Questions from Fort Belvoir neighbors
Is it worth upgrading right before a PCS move?
Often, yes. A solid-state drive also holds up better to bumps in transit than an older spinning hard drive. We’ll back everything up first so you’re protected either way.
Will I lose my files or programs?
No. We copy your whole system onto the new drive, so your files, programs, and settings are exactly where you left them.
What about Windows 11?
We can check whether your computer can run Windows 11, upgrade it if it can, and help you weigh your options if it can’t.
