Updating from windows 2016 to xp
In January 2014, Tech Pro Research surveyed Tech Republic members about their migration plans from Windows XP.
The report (available freely here for Tech Republic members) found that 37% of respondents said they intended to continue using Windows XP.
Extended support for Windows Embedded POSReady 2009—the last supported version of Windows based on Windows XP—ended on April 9, 2019, marking the final end of the Windows NT 5.1 product line after 17 years, 7 months, and 16 days.
Counting this edition, Windows XP is the longest-lived version of Windows ever—a record that is unlikely to be beaten.
In the United States, Windows XP’s use as a desktop OS has been declining. S., those numbers may disguise the presence of Windows XP systems in business.
According to the federal Digital Analytics Program's (DAP) analytics page, in the past three months Windows XP was used by only 0.6 percent of users. According to a study, 2017 OS Adoption Trends, conducted by Spiceworks, a Windows help desk company and network of IT professionals, 52 percent of businesses are running at least one Windows XP instance, and the OS is still installed on 14 percent of business computers. Some rough calculations put the number over 100 million Windows XP users.
For current deployments, updating sooner rather than later is advisable.
Alternatively, the perennial Windows alternative React OS is still in active development.
It’s been three years since April 8, 2014, the end of mainstream Windows XP support.
Of note, Windows Update will require SHA-2 encryption support as of July 16, 2019 to continue receiving updates.
It's probably a safe bet that Windows Update will continue to work normally until then, though guarantees are impossible.
Microsoft did go to the extraordinary step of patching Windows XP systems against Wanna Cry, deploying the update created for Embedded Standard and POSReady 2009, though 98% of Wanna Cry victims were using Windows 7.
Notably, 11% of respondents in the survey indicated plans to migrate systems to Linux, with 1% planning migrations to Mac OS X.
