To check if a second-hand phone you are interested in buying is stolen, logon to DeviceCheck.ca. Just enter the IMEI number. This is a unique number in every phone and cannot be changed.
To discover the IMEI number, open the Phone app and dial *#06# on your keypad.
If you find that you cannot read or write or delete files on a drive, whether a memory stick, SD card or hard drive this can be fixed in two ways. The typical method is to right-click on the drive letter (e.g., C: or E:) and on the Security tab select Edit and uncheck any of the boxes that have Deny for permission.
If that fails because those options aren't available do the following:
1. Press the Windows key + R to open the Run box. Type diskpart and press Enter.
2. If you receive a User Account Control prompt asking for permission to continue, click Yes.
3. At the DISKPART> prompt, type list disk and press Enter.
4. Select your USB flash drive with the select disk command. In this example, we want to work with disk 1, so the command is select disk 1.
5. You can list the attributes of the disk with the command attributes disk.
6. To clear the read-only attribute (making the disk writable), use the command attributes disk clear readonly.
Or, to set the read-only attribute (making the flash disk write-protected), use the command attributes disk set readonly.
7. When you are finished, type Exit to quit the program.

You may want to upgrade the memory on your computer, either the RAM to improve performance or the hard drive to increase storage capacity.
First you need to find out what memory you currently have. To find this, hold down the Windows key and press the Pause key, or alternately you can go to the Start icon in the lower left of your screen (on Windows 10) then go to Settings > System > About.

The installed RAM on this device is 8.00 GB. But before you look at upgrading your RAM you need to check if expansion is possible. To do that you need to check on the maximum physical space available.
To check this first hold down the Windows key and press R; type cmd into the search box and press OK. This opens the command line window.
Next type the following and press return: wmic memphysical get maxcapacity

The number that appears is the maximum physical capacity of the computer in kilobytes. You can type or copy the number that appears and, using a calculator, divide by 1,000,000 to get the maximum capacity in gigabytes.
For this computer that would be 8388608 divided by 1,000,000 is 8.388 gigabytes, so this computer already has the maximum amount of RAM possible at 8 gigabytes.
To find out the size of hard drive on your computer, go to the search window beside the Start icon and type msinfo32 and press Return. The window below will appear. Select the plus sign (+) beside Components to expand the menu, then do the same for Storage and select Disks. The line Size shows the hard drive capacity. So this computer has a 500gb hard drive. This could be upgraded to a 1 or 2Tb drive, but this would involve backing up all your files on the computer to another drive and then reinstalling Windows.
