An HP laptop running the Microsoft Windows 10 operating system that I was using
was performing poorly and when I checked the system's performance with the Windows
Task Manager, I could see that the memory utilization
was consistently high. So I decided to check on whether I could increase
the memory in the system. A sticker on the underside of the laptop showed
the model number to be G70-460US. I wondered whether I could also
get the model number from a
Windows Management Instrumentation Command-line (WMIC)
command if the sticker was no longer present or was illegible, so I opened a
command prompt window and checked to
see what information I could get using the wmic csproduct get
I recently removed
Trojan:Win32/Nymaim, which was detected by
Windows Defender on a Microsoft Windows 10 system. When Windows Defender
detected that malware, it prevented the weekly backup program on the system,
which was the Windows 7 backup and restore utility, from completing
successfully. After removing that malware, I ran the backup program again, but
I found that again the backup program did not complete successfully due to
Windows detecting a
trojan during the backup operation. This time it was
When I checked a Windows 10 system to ensure that the Windows 7 backup program
that is scheduled to perform weekly backups of the system was functioning
properly, I found that the last successful backup occurred on November 11, 2018.
When I clicked on "More information" to determine the cause of the weekly
backups failing, I saw the message "Operation did not complete successfully
because the file contains a virus or potentially unwanted software." So I
opened the Windows Security application by clicking on the Windows Start button,
then selecting Settings, then Update & Security, then
Windows Security. I then clicked on Virus & threat protection
and selected Protection history, which showed an entry of "Remediation
incomplete" for the backup that ran on February 16, 2020. The issue encountered
was listed as "servere." I clicked on the downward-pointing arrowhead next
to "severe" which showed the following for the malware detected:

Microsoft Windows 10 comes with a backup program that will allow you to create
a system image for backups. You can get to it by right-clicking on the Windows
Start button and choosing "Settings" then "Backup," which is under "Update &
Security," and then selecting "Go to Backup and Restore (Windows 7)." That
program was being used to backup a Windows 10 system every weekend, but when I
checked the status of backups for the system, I saw a message stating "The last
backup did not complete successfully."
I clicked on the "More information" button and saw a "Check your backup"
message stating that the "Operation did not complete successfully because the
file contains a virus or potentially unwanted software."
When I clicked on "Show Details," I saw the time of the failed backup
and "Error code: 0x800700E1."
When I ran a scan of a Windows System with
Spybot Search & Destroy 1.62, it reported it found a
registry key associated with GhostMail - it identified
GhostMail as adware. To check the registry key, I typed regedit in
the "Type here to search" field at the bottom of the screen and then selected
the "Registry Editor" app when it appeared in the list of returned results
(you can also open the application by typing regedit and hitting
enter at a command prompt. I then
navigated to the relevant key. I wanted to determine when the registry was
created or at least when it was last modified. You can't see that information
in the Windows
Registry Editor, but you can create a text file that will
contain that information by right-clicking on a key and choosing "Export" to
generate a text file - select "Text Files (*.txt)" in the "Save as type" field,
not the default value of "Registration Files (*.reg)."
text file will contain the key as well as
the time it was last written to:
In this case, the date on the key was months ago, so didn't explain recent
problems on the user's PC and since Spybot - Search & Destroy didn't
locate anything else, the registry key may have been a remnant of something
removed many months ago.
I downloaded SUPERAntiSpyware
Free Edition version version 8.0.1048, an antivirus program,
from the developers website on January 27, 2020. When I attempted to install it
by right-clicking on the file and choosing "Run as administrator, a
window popped up with the message below:
Windows protected your PC
Windows Defender SmartScreen prevented an
unrecognized app from
starting. Running this app might put your PC at risk. More info
When I clicked on the "X" at the top-right, hand corner of the window,
the message went away, but the installation did not start.
A user reported her Windows 10 system was running slowly. When I connected to
the system remotely to check it after the user had left for the day and closed
all the applications she had running, I found that the memory utilization was
78%. I knew the system was a Dell PC, but I didn't remember the model number.
I was able to determine it was an Inspiron 570 by right-clicking on the Windows
Start button and choosing System. Under "Device specifications," I
saw "Inspiron 570". I also saw that the system had only 3 GB of memory
When I tried to install Minecraft on a Microsoft Windows system using the
Installer file I had downloaded, I saw the error message "These libraries
failed to download. Try again. org.ow2.asm:asm-all:5.2."
I then clicked on the link for "Installer" rather than "Windows Installer on the
website from which I had downloaded the installation file, which resulted in a
.jar file being downloaded. I right-clicked on the .jar file,
forge-1.12.2-188.8.131.5268-installer.jar, and chose "Open with" then "Java(TM)
Platform SE binary". I was then able to install the Minecraft client. When the
client was successfully installed, I saw the message "Successfully installed
client profile forger for version forge 1.12.2-184.108.40.20668 into launcher and
grabbed 1 required libraries."

posted, but I am posting now in case I encounter a similar error again.
I needed to compare two Excel workbooks produced with Microsoft Excel for
Mac (version 16.29) on my
Pro laptop. Unfortunately, the MAC version of Excel doesn't include a
capability to directly compare two workbooks. Since both workbooks only had one
worksheet in them, I created a new workbook and then copied the
contents of the worksheet in the first workbook to Sheet1 in the
new workbook and the contents of the worksheet in the second workbook
to Sheet2 in the new workbook. I copied the contents of the
worksheets by selecting Edit and then Select All
in a worksheet and then pasting the contents into a sheet in the
new workbook. I then created a third worksheet, Sheet3 in the new
workbook. In cell A1 in that workbook, I put the formula
=IF(Sheet1!A1 <> Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs
Sheet2:"&Sheet2!A1, ""). I clicked in that cell and then
clicked on Edit and then Copy. Since the columns
in both of the worksheets I wanted to compare extended to AE with
804 rows, I then selected all of the columns from A to AE and all
rows from 1 to 804 and then clicked on Edit and then
Paste Special with All selected. I then clicked
on OK to copy the formula throughout the new worksheet.
Excel automatically updates the references so that B2, for instance,
gets the formula =IF(Sheet1!B2 <> Sheet2!B2,
"Sheet1:"&Sheet1!B2&" vs Sheet2:"&Sheet2!B2, "").
Excel then showed the differences between Sheet1 and Sheet2 in Sheet3
where I had used a formula to compare cells in the two other sheets.
If the contents of a cell differed, Excel showed the differences.
E.g. for cell A71, I saw Sheet1:I13-0003 vs Sheet2:I97-0033, since
Sheet1 had I13-0003 in that cell whereas Sheet2 had I97-0033
. If the cells matched, the corresponding cell in Sheet3 was empty.
So, even though the Mac version of Excel doesn't include the workbook
comparison feature found in Windows versions of the program described at
How to compare two Excel files for differences, you still may be able
to compare sheets in two Excel files by copying relevant sheets into a new
sheet where you can see the differences displayed. In the exmple above, the
contents of E71 in Sheet3 showed the values for the other sheets as numeric
values, though there were dates in the corresponding cells in Sheet1 and
I needed to determine the amount of memory currently in a PC running the
Windows 10 operating system and how much more memory could be added to
the system in order to improve its performance. To determine how much memory
could be added, since it was a custom-built PC, I needed to determine the
motherboard in the system. I didn't want to disconnect every device attached
to it and open it up, so an option is to use Windows Management Instrumentation
Command-line (WMIC) commands to determine the motherboard manufacturer and
model number. You can also use WMIC commands to obtain details about the memory
already in a system.
