All PCs of the Ebata have finished to replace old windows OS to Windows10.

Based on the pervious success, I purchased the OS license from the same EC-shopping site.

I could get it for one-tenth of the price of the Amazon.com.

I don't know the reason, however, the license seems to be legitimate. I don't think about it deeply.

This time, the OS seems to work well without telephone authentication.

I am moved that the Windows10 OS works well even on the 32Bit PC.

PCs are said to be very fast obsolete, however, I think that PCs work if we set correct the parameters of OS.

Except for a system engineer who have always tried to withdraw the best performance of the PC, the PC life time is going to be longer.

The reason of an accident that "a new OS cannot work on an old PC" is largely due to the default setting of the OS.

For example, there are the following

However, there are few people who can tune the setting of OS

Which is cheaper,

(A)education to make them possible to set the parameters of OS, or

(B)replacing with a high-performance PC

The (B) is absolutely cheap.

As a result, the PCs that are still usable are discarded as trash.

How pity and waste they are, but this is a real story.
