running application as administrator in regular user login in windows

It’s been an awkward condition in the host I’ve been setting. It is that the application windows live mail unable to run properly in non administrative user. for example, I can’t delete or add contact in user level, but I can do it in administrator level.

The picture is too large and will be truncated

There is an error that microsoft seems to happen that not related with the description it is thrown:

This error: “The picture is too large and will be truncated”
It was triggered in my case when I copy (ctrl+c) a column in excel, which was contain only text/number, no picture.
After researching in the internet, I find that this error is triggered because of some conflict with the clip board.
So there are two things that can modify the state of clip board: the memory manager (RAM cleaner) program that can erase/optimize memory.
And program that share clip board, like remote connection program Teamviewer.
For the first cause you must terminate the program while you using Office.
For the second cause, just turn of the option to share the clip board
For example with Teamviewer: you go to Extras>Option>Advance>Clipboard synchronization and uncheck it.

Windows live mail working offline

you know there are some strange things happened in one of my client WLM, it was always toggled as working offline. whenever we change it to working online, it always revert back to offline.
after scourging the internet, like always, microsoft link the Internet explorer to their other programs like microsoft explorer and of course their own windows live mail.
so you just go to IE, go to file, and uncheck the working offline option.

preventing chkdsk to work on start up

Now there are sometimes annoying thing where after improper shutdown, like hot restart or shutdown, or power down, the windows start by the option of checking the disk.
Or in my experience happened sometimes in multiple OS computer, like when I shutdown normally from windows 7 then starting in windows XP sometimes this thing happened.
The windows does checkdisk to logical drive that has been marked dirty. you can check if the drive is dirty by using this command line:

fsutil dirty query [drive name]:

example:

fsutil dirty query c: d: e:

the above command is used when you want to check if drive c:, d: and e: are dirty.
to change the dirty status of the logical drive you can use the command:

fsutil dirty set

now that only work once, if you want it to be permanent, you can use the command line:

chkntfs /x [drive name]:

just be careful when using this, since even when the drive ntfs is bad, the windows wont repair it on start up. you can do it manually btw.
