Some systems specify the operating system,
Some systems specify the version of the browser,
So the application system is not upgraded, the corresponding office computers can only remain unchanged, and has been used to let the upgrade to upgrade only upgrade.
It's not necessary to start all over the world
It just so happens that the hospital has information technology business dealings. It's not that they don't want to use the new system, it's because the medical software (his, lis, pacs, etc.) and the medical equipment (ultrasound, test, X-ray, etc.) are based on the xp development, and if you change the system, these things will be unstable, and even can't be used.
Most of these computers are hospital intranets or not networked, plus a long time the computer running smoothly, of course, will not be upgraded (for example, a long time running smoothly computer, looking good, as long as the dust or reboot or something will hang, so as far as possible will not be moved)
Of course there is a cost issue, a hospital will have a large number of computers, these computers are just upgrades is A hospital will have a large number of computers, and just upgrading them is a lot of money (bulk purchases are mostly for whole computers), and new computers don't have a long survivor bias, and may have problems at one time or another. Software because the system is not compatible with the need to upgrade (Win7 compatibility mode for this type of software is generally not useful), the genuine version to a sum of money, if the genuine version is also incompatible or simply no subsequent version, only to change the software is a new cost.
1. Many units of computers are c/s or b/s, the resources are on the server, the machine is essentially not relevant, do not have to upgrade the old; 2. Many of the systems developed earlier, the client's operating system is dependent on, in particular, imported products, upgraded can not be installed and used. 3. The original XP direct installation and use, and later need to be activated to use the upgrading is also a small cost. The first time I saw this, I was able to get the best out of it, and I was able to get the best out of it, and I was able to get it out of it.
The reform process is too cumbersome and involves a lot of things
The future is certainly upgraded, but it is not that simple. There are a lot of different systems out there
Enough is enough, the Rocket's computers haven't been upgraded for a long time
The XP system is stable
It's just enough to be able to use it and there is no need to do so!
