I have a problem in c prompt to work ? when i type c:then it come back on same as above c:documents and users

The extensions shown for the files are used by the computer to open them with Libre Office or with any other program such as Microsoft Office. It is possible the default was accidentally changed to Microsoft Office or some other program somehow.

https://www.techrepublic.com/blog/smb-technologist/help-migrate-users-from-microsoft-office-to-libreoffice-41/

Quoting from the link above: "LibreOffice defaults to the open document format. In other words:

• odt - text documents
• ods - spreadsheets
• odp - presentation

If your users create documents using the default file type and then send those documents to Microsoft Office users, there could be problems. You can configure LibreOffice to use the Microsoft Office defaults instead"

Which administrator account are you talking about? The 'real' administrator or your normal "administrator group" account? If it's you normal account do you have another account with administrator privileges?
Rather than wait for answers I'll cover the above three possibilities. If it's something else I'll need more input.
1) If it's the real administrator, this is a fairly easy fix (that I had to do the other day because my OEM set a password for the account).
·Open Control Panel > User Accounts and select the option that allows you to change other accounts;
·Select the Administrator account;
·Turn off password required. Changing this option will not require a password.
2) If it's your own account but you have another account on the system with administrator privileges, the procedures above will work as well here.
3) If it's you own account and no other account has administrator privileges it will be much more complicated.
First, make a try at changing the account you are in to administrator. It's unlikely this will work and would be a major security hole, but it's worth a shot.
If that doesn't work, try booting to a command prompt and activating the real administrator. The procedures at this link attached with this post/answer, will walk you through booting to a command prompt. Once at the command prompt type the following two lines:
Net user administrator /active:yesNet user administratorp@ssw0rD Notes: 1) These two lines can be in any order; 2) "p@ssw0rD" is an example, type any password you ; and 3) The password line may not be needed in your case. I added it because my OEM set a password on my new computer. If they did on yours as well, you would have to boot back to a command prompt to change the password later so may as well do it now. You can always turn it off later.
Once you have the real administrator activated, boot back up and logon to the administrator account. Once there, use the procedure from "1)" above. this third possibility may not work, I've never actually had to try it this way, but it makes logical sense.
Good luck.

Blue screens mostly appear because of a hard ware issue. A device in your system has a problem.
Most likely there is a problem with the FAT, File allocation table of your HDD. Suggest you back up all your data to CD/DVD disk or to a second drive if you have a second HDD in your system.
The most common files to back up are:
C:\Documents and Settings\ User name\Application Data\Microsoft\Address Book
C:\Documents and Settings\ User name\Desktop
C:\Documents and Settings\ User name\Favorites
C:\Documents and Settings\ User name\Local Settings\Identities
C:\Documents and Settings\ User name\My Documents
Every blue screen usually shows some type of error message. Write down the information shown on your screen. Than search Microsoft's web site for a possible work around to fix your error message/Blue screen. If you are unable to find a fix through Microsoft you can try the command: C:\ fixmbr. As your system begins to start up press the F5 key on your keyboard every 2 seconds. Windows will display a bunch of options. Using the keyboards up & down arrow keys move to highlight: Safe Mode With Command prompt. Press the enter key.
At the command prompt type, C:\space fixmbr & press the enter key. Than restart your system by pressing the keys, ctrl+alt+delete Your system should restart. If you still receive the blue screen you'll have no choice but to load your windows CD & format your drive. Than install windows fresh. If your hard disk drive is large enough, say 100 to 250GB in size. You can load your windows CD into your CD-ROM drive & boot to the Win CD. Read each screen. You want to create a partition within the free space of your drive. By doing the above you will not need to back up your data. Once your system seems to function you can delete the old partition by running, diskmgmt.msc in your windows run window.

Cheers!

Hi dalenaftzger, windows can not load your primary partition. One of your partition is damaged. Dell
Hi dalenaftzger, windows can not load your primary partition. One of your partitions is damaged. Dell systems have more than one partition on their hard disk drives. Two partitions are hidden. Try this;
Start up the computer and press F12 key to give you the boot-up options.
Insert Windows Installation/Recovery CD into your CD-ROM. Choose CD-ROM boot option & press enter.
Let the installation process continue until it prompts you to, Press R to repair. This should then take you into the DOS mode. Type in FIXBOOT & when prompted, press "Y" to start creating the new boot partition. If everything goes right, you should get a message saying the partition was corrupted and a new one was created successfully. Remove the CD & reboot your system.
Play it safe if your system boots windows. Check windows for any updates. Run a full system virus scan. Run windows check disk & windows defrag.
Just in case the drive is starting to go. If you have a CD/DVD writer start backing up your personal data. The most common folder to back up are:
C:\Documents and Settings\ User name\Application Data\Microsoft\Address Book
C:\Documents and Settings\ User name\Desktop
C:\Documents and Settings\ User name\Favorites
C:\Documents and Settings\ User name\Local Settings\Identities
C:\Documents and Settings\ User name\My Documents
Data from any program you may have installed.
Armed with the above folders backed up to CD/DVD, you'll loose very little if you have to replace the hard disk drive.

Good luck dalenaftzger!

Hi-

At the Start Orb in the "search" box type:
cmd [enter]
You wil see cmd appear above. Right-click it and "run as Administrator".
This will give you an elevated command prompt. Type:
net stop spooler [enter]
You should get a confirmation that the print spooler is stopping. Leave
the command prompt available (don't close it out) and now you should be
able to open the Properties for that printer and delete any pending
documents. Once the documents are deleted, you can remove the printer.
Always check in the Programs & Features Control Panel applet first to
see if there is any software connected with that printer you need to
uninstall first. If not, then right-clicking on the printer in the
Printers applet should allow you to delete it.
Once you have finished with that printer, go back to the cmd prompt and
type:
net start spooler [enter]
update me for result
