What is the difference between 2.4 GHz and 5 GHz wireless networks?

We get this question a lot.

The primary differences between the two frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.

How to list Active Directory groups for a pc and user.

I have been using Microsoft Group Policy more lately and would like to post this as a reminder.

A good troubleshooting tool for group policy is the command "gpresult /r"

This should be run from the command prompt as the user logged in.

This will show which policies have been applied as well as list the active directory groups the user and computer are a member of.

Windows 10 Anniversary update hangs at spinning balls.

I just attempted to install the Windows 10 Anniversary update and upon reboot the computer seemed to hang on the spinning dots or balls.

After letting it sit for over 8 hours i had to hard power cycle it. Upon restart again the pc started to roll back the changes.

I thought i was in the clear but the next time windows updates ran it did the same thing and hung at the same black screen with spinning dots.

After hours of research i found a tip that worked.

The next time I ran windows updates it hung again at the same screen.

I simply unplugged the wireless mouse receiver and the screen progressed to a Windows screen with the prgress percentage.

Not sure it this will work for everyone but
ItFixed it for me.

How to get a list of folders only to be used in a batch file

I have been asked a few times "How do I get a list of folder names only to be used in a windows batch file?"

There a likely several ways to accomplish this depending on your intended use but for a simple list of folders found in a particular directory you can run the command below

dir /B /A:D-H-S

This command will display a list of folder names only without any time stamps or file sizes. It will not show Hidden or System folders.
This can be used if you wanted to loop through these folders in a batch file and perform another action on each folder.

The /B switch is for "bare format"
The /A:D-H-S shows only Directories (D) and does not show Hidden(-H) or System(-S) files

You can also pipe this to a text file if you wanted as well by using

dir /B /A:D-H-S > directory-listing.txt
To read more about the dir command options you can also type the following from a windows command prompt.

dir /?

Hope this helps.

How to install older version of Android apps

Ran into a problem with an automatic update on my Android phone (Galaxy S5)
An update caused the app to force close on every attempt to open it.

If this has happened to you you know how frustrating it can be if you have to wait for the developer to fix and update the app again.

If you can't wait there may be an option for you to save some sanity.

Please use this at your own risk.

Android app are sent to your phone in a formate called and APK file.

There is a site called APK Mirror that has downloadable versions of many Android apps all sorted by date. It does not have every Android app but does have many of the most popular such as Facebook and Google Chrome etc...

Im my case I downloaded the prior version apk file of the app in question to my phone.

NOTE that you may need to change a setting on your phone that allows you to install apps from third parties.  As there are too many phone to give details on this you will have to search for specific instructions to enable this on your phone.  However many phone have this setting listed under SETTINGS then SECURITY.  Look for the checkbox for the setting.

Again please use this at your own risk but It Fixed it for me.

Two useful Linux commands

I came across a couple of Linux commands that I have not used before and wanted to share them in case anyone else find them useful. I used them to determin who was on a linux server as well as when the server last rebooted for troubleshooting a web server problem.

The command are 
From the man page:

       last, lastb - show listing of last logged in users

       last  [-R] [-num] [ -n num ] [-adFiowx] [ -f file ] [ -t YYYYMMDDHHMMSS
       ] [name...]  [tty...]
       lastb [-R] [-num] [ -n num ] [ -f file ] [-adFiowx] [name...]  [tty...]

       Last searches back through the file /var/log/wtmp (or the  file  desig‐
       nated  by  the -f flag) and displays a list of all users logged in (and
       out) since that file was created.  Names of  users  and  tty's  can  be
       given,  in  which  case  last will show only those entries matching the
       arguments.  Names of ttys can be abbreviated, thus last 0 is  the  same
       as last tty0.

The other is a variation of the first and shows a list of reboots on the pc or server.

last reboot
From the man page:
      The pseudo user reboot logs in each time the system is rebooted.   Thus
       last  reboot will show a log of all reboots since the log file was cre‐

Hope this helps.

How do I include the date in a Windows Batch file?

I have used this many time in Windows batch files.

You can set any variable, in my example below called "thedate" to a substring of the computers date to produce only the numbers without any "/" in case this needs to be used in creating folder or file names.

For my example I would like to use a script to create a photos folder with the date in the name:

set thedate=%date:~-4,4%%date:~0,2%%date:~-7,2%

then you can show your output

echo %thedate%
 I then use

mkdir photos_%thedate%

to create a folder called "photos_20150727"

The above was created using Window 7.

Hope this help

How many innocent pc users fall for this trap?

Another not really new but new enough phone scam is going around. 
The companies and callers could sound very legitimate using all the correct buzz words but they are just tyring to fool you into giving them your credit card.

The scam goes like this.
  • You may get a call caliming to be from "Microsoft Support" or another Computer Tech Services company claiming that your pc is infected and they they need to connect to your pc to fix it. 
  • If you fall for this, the company will charge your credit card and then pretend to fix your computer. but in reality not do anything (or could even be infecting your pc further)
  • After a couple of days a second call may come alerting you that the first caller was a scam and that for an additional large sum of money they will clean up what the first scam company did.
  • They would then charge your credit card again.

You have now be scammed twice likely by the same company.

Most of these scams orginate from outside of the USA so there is little that anyone can do to prosecute these criminals

Always use uptodate Antivirus and Antimalware software.
For some of my recommended programs please see this link

I hope this prevents even one user from falling for this.
