I installed the Windows 10 upgrade on my laptop. But I
didn’t like Windows 10, so two weeks later I reversed
the upgrade and went back to Windows 7. Then I started
receiving messages from Microsoft that my copy of
Windows 7 was counterfeit. I tried to reload Windows 10,
but my Windows 7 "product key" was rejected
and I couldn’t perform the upgrade.
there a fix?

Your brief upgrade to Windows 10 has created some
electronic confusion that makes Windows 7 appear
counterfeit. That’s why you’re getting warnings from
the upgrade got to do with it? Normally, you have 30
days to switch from Windows 10 back to Windows 7. After
30 days, the Windows 7 product key (a kind of password
that verifies you have a legal copy of Windows) stops
working and your old Windows 7 files are deleted.
you used Windows 10 for only two weeks, so if your
Windows 7 product key has quit working, then something’s
wrong. Here are some potential solutions you can try.
Complain to a Microsoft representative. You can do that
by setting up a free account with the Microsoft Answer
Desk (see tinyurl.com/nhor9v6). After signing up, you
can request to talk to a Microsoft worker via online
chat or telephone. The representative will tell you
whether your problem can be fixed for free or if you’ll
have to pay $99 an hour for help.
Try reactivating Windows 7. Go to Start, right click on
"computer" and select properties. On the
resulting menu, click "Activate Windows now."
On the list, first try "Retype your product
key." (To find the key, see tinyurl.com/nch3av6.)
If that doesn’t work, click "Use the automated
phone system to activate." (Choose the nearest
location and you’ll be given a phone number.) As a
third choice, click "Buy a new product key
Download a new free copy of Windows 7 to a DVD disk or a
flash drive (see tinyurl.com/q7p2g7e). Then, after
backing up all your PC’s data to an external disk
drive or flash drive, install the new copy of Windows 7.
Doing so will wipe out everything on your hard drive.
(This is the option offered to those who waited more
than 30 days to reverse the upgrade.)
My Dell Inspiron 15R N5110 laptop won’t stay in
energy-conserving sleep or hibernation modes. It wakes
up at random times, even if the lid is closed. I
disconnected the PC from the Internet, but that didn’t
make any difference. Is there a solution?

Among the possible causes of a PC waking up prematurely
are a wireless mouse with old software drivers (to
download new drivers, see tinyurl.com/ol72d9l) and
incorrectly configured PC power settings (the hard drive
and the display screen should be set to go to sleep at
least a minute before the PC does.) For details on these
fixes, see tinyurl.com/2uelqm.
