As we said before, for the final transition to permanent winter time in Windows XP / Windows Server 2003 necessary disable automatic switch to daylight saving time... Otherwise January 7, 2015 hours in these OS will be automatically set forward 1 hour. And, if a special patch was released for Windows Server 2003 (it must be installed before January 7, 2015), then for Windows XP this update is missing due to the.
Let us remind once again the procedure for switching to winter time in Windows XP / Server 2003:
- Until 10/26/2014, you need to add to the system a list of new time zones for Russia (in Windows 2003 this is done special, in XP -) and select the appropriate time zone for the region. After this operation, the reverse transition is set in the time zone settings. summer time on the first Wednesday of January 2015.
- At any time after 26/10/2014, but before 7/01/2015) - disable automatic transition to seasonal (summer) time
Using the TZedit utility, we check that the seasonal time change is enabled.
Advice... To make sure that the clock in Windows XP will be set by the system, you can change the time to January 6, 2015 23:59. Exactly at 00:00, the hands of the clock should move forward 1 hour.
Based on the changes that are made to the time zone settings in Windows Server 2003, an update for Windows XP prepared a reg file with new time zone settings, in which daylight saving time was disabled. With these settings, the transition to seasonal time in this OS will no longer be performed.
This reg file needs to be imported into the registry and check if the correct time zone is selected.
You can import the reg file manually by double clicking on it and confirm the changes to the registry 
either from command line So:
The same operation can be performed via group policies by creating a policy for computers with Windows XP (you can filter out machines with XP, for example, using), and assigning a logon script:
Reg import \\ corp..reg
Note. Reg file TimeZone-WindowsXP-Step2.reg must first be copied to the domain controller in the NETLOGON folder and wait for replication to complete (if there are several sites with DCs in the network).
Make sure that Daylight Saving Time is disabled in Windows XP. 
Important... If you forget to complete this operation in a timely manner, you will receive a "Christmas present" in the form of daylight saving time on the night of January 7, 2015.
On Windows 7, Windows 8, Windows Server 2008/2012, nothing extra is required. This change has already been made to the system by an update for the transition to winter time -.
Recently, we all faced an innovation - the cancellation of winter time. The problem lies in the fact that Windows knows the date of the transition to winter and summer time, but the system does not even know about the cancellation of this transition. So Windows clock that switched to winter time, show 1 hour less than real time. And this problem has 2 solutions. Downloadable special update for your Windows versions by this link support.microsoft.com/kb/2570791/ru
But there is also a second solution to the problem. You just need to choose a different time zone. Now we have set the time zone +3 Moscow, St. Petersburg, Volgograd, and due to the addition of an extra hour, we need to select the time zone +4. We'll look at how to do this on Windows example Vista.
So, left-click on the clock icon (Fig. 1).
Click on the inscription " Changing the date and time setting"(Fig. 2).
Here we see the time zone set to +3. Of course, you can use the button " Change date and time»And just move the clock forward 1 hour. But do not rush to do this. Windows may determine that the time is displayed incorrectly, and with good intentions will set the clock back 1 hour so that the time on the computer corresponds to the time zone. Therefore, we will change the time zone. Click on the " Change timezone"(Fig. 3).
First uncheck the box next to the phrase “ Automatic transition for summer time and back". Now choose 1 from +4 time zones (i.e. 1 hour more) (Fig. 4).
