Sometimes a System Restore operation has the unintended consequence of messing up a program you recently installed. The net effect is that a program may appear to be installed but is missing vital files that were “unhooked” by the System Restore operation. Because you probably ran System Restore to recover from a disaster, I don’t recommend undoing the System Restore. Instead, what you need to do is reinstall the program that’s screwing up. Doing so reconnects the items that System Restore disconnected.
Like most technology, PC power management is rife with specific terms and names for its modes of operation. Here’s the shortlist:
hibernation: In this mode, the computer’s current state is saved and the PC turns itself off. When you turn on the system again, the
saved state is restored and you can continue working.
hybrid sleep: A cross between hibernation and sleep, this mode saves data for a fast recovery but doesn’t quite turn off the computer.
This mode is enabled by default in Windows 10.
sleep mode: In sleep mode, the computer slows down to save energy. Certain peripherals are disabled and the processor enters a low-
power mode, but the entire system isn’t shutdown.
suspend: This is another name for hibernate.
