will i still be able to install OS on new motherboard but it is illegal or THE MICROSOFT will going to detect it and they will not let me install it on new motherboard???
Technically, you will be able to install the operating system with the new board. But note that is like running a Stop sign. Technically you can - but legally? (See note below).
Will you get caught? Maybe. After you install the OS, you will need to authenticate it with Microsoft and it is then it may be detected as having been installed on another computer. You may be instructed to contact Microsoft, where you will be expected to tell them the truth about what you are doing. Not telling the truth is deceit, or legally called "fraud".
if my motherboard is got damage and cant be use anymore and i bought a new motherboard will it be okay to transfer my OS to new motherboard if its OEM??
If you are replacing the old motherboard with a new motherboard as part of a repair action because the first board failed, then you can use the same license only IF
the replacement board is an EXACT
model replacement from the same maker. If the original model is no longer in production, you must use the suggested replacement by the same board maker. You can NOT
take that opportunity to "upgrade" to a newer, better board.
you said OEM Is tied with original motherboard but what if im not using it anymore and just use the new motherboard??
If the OEM equipment is no longer being used, then the OEM Windows license gets retired with the hardware. Period. No exceptions. If you giveaway or sell the computer, the license (and installation disks) should go with it.
Bottom line in the vast majority of circumstances is this: new motherboard = new computer therefore requires new OS license.
if its full retail version can i use the disk to install on computer as many as i want????
Yes, but it can only be installed on one computer at a time. If you buy/build a new computer, you must uninstall the old installation first.
NOTE: With "branded" OEM licenses - "branded" being OEM disks from Dell, HP, Acer etc. that have been "branded" or labeled as from Dell, HP, etc., - are often modified or hard-coded to look for their own branded products. That is, if the OEM disk came with a Dell computer, it is likely the Dell disk will look for Dell BIOS information during the install. And if your new motherboard is not from Dell, the install will abort.
Is it fair? Yes. If you want to have flexibility, you buy the full retail license. If you want to save some money, you buy the less expensive OEM license and put up with the limitations. Of course, if you want to save more money, or want to avoid making Microsoft richer, you have the option of using one of the many capable and "FREE
" Linux alternatives.
