The restore points of WinXP and Win7 are stored in the SystemVolumeInformation folder (hidden attribute) in the root directory of the partition. As long as a restore point is created in a certain system, the restore point of the same partition in another system will be destroyed. This means This caused the situation that the author encountered earlier. How to fix it? The following takes the most common menu-based multi-system as an example.
Protect restore points in system partition
Take WinXP and Win7 installed in two partitions, C and D respectively. By default, the WinXP system will create a restore point for each partition, while Win7 will only create a restore point for the system partition. After knowing this principle, the method to protect the system partition restore points under the two systems came out - just disable the restore of the system partition where Win7 is located, that is, the D partition in WinXP.
Right-click "My Computer" and select "Properties → System Restore", then select the D drive under "Available Drives" and click "Settings" and then check "Turn off System Restore on this drive".
Protect restore points in non-system partitions
Some friends like to install application software in non-system partitions. In this case, they need to create restore points for the software partitions. So how to avoid creating restore point conflicts? Simple, just hide the software partition of another system in one system, so that there will be no problems when creating restore points.
Here we take the application software partitions of WinXP and Win7 as E and F drives respectively as an example. In Win7, right-click "Computer" under the start menu and select "Manage → Disk Management". Then right-click the E drive, select "Change drive letter and path" and click "Delete" (as shown in Figure 2), thus "delete" the WinXP software disk in Win7.
Don't worry, this operation can only delete the drive letter assigned to the partition by the system, not the partition itself, and it is only effective for the current system. Therefore, after booting to WinXP, this partition can still be displayed normally without any "toxic side effects" O(∩_∩)O (the method of hiding the F drive under WinXP is the same).
Creating a system restore point can restore the system to its most recent normal state when a system problem occurs or crashes under special circumstances. It can also minimize user losses, so users should develop a good habit of regular maintenance. We have already talked about this, Master Dong will not say more.
There are many users installing Win7 now, and many users have also chosen to install a dual system of WinXP+Win7. However, in dual systems, conflicts may occur when creating system restore points. If this results in data loss or the system cannot be restored, it will be worth the loss. So you can set up the system through the methods in this article to avoid unnecessary trouble.
