## Abstract

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a thin client. The thin client captures, at a first restore time point, customized configurations of the thin client stored at a first storage location of the thin client. The thin client then obtains first default configurations of the thin client that are in use. The thin client further determines a difference between the customized configurations and the first default configurations. The thin client stores the difference between the customized configurations and the first default configurations as a configurations difference in association with the first restore time point at a second storage location of the thin client.

obtaining second default configurations of the thin client that replaces the first default configurations;
determining a default configuration difference between the first default configurations and the second default configurations;
determining a second difference between the customized configurations and the second default configurations based on the first difference and the default configuration difference; and
replacing the first difference stored at the second storage location in association with the first restore time point with the second difference.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
capturing, at each of a plurality of restore time points in addition to the first restore time point, respective customized configurations of the thin client stored at the first storage location;
determining a respective difference between the respective customized configurations at each of the plurality of restore time points and the first default configurations; and
storing the respective difference between the respective customized configurations at each of the plurality of restore time points and the first default configurations as a configurations difference in association with that restore time point at a second storage location of the thin client.

### Claim 3 (depends on 2)

The method of claim 2, wherein the first restore time point and the plurality of restore time points are time points specified by a predetermined schedule.

### Claim 4 (depends on 2)

The method of claim 2, wherein each of the first restore time point and the plurality of restore time points is selected in response to a determination that the customized configurations stored at the first storage location have been modified.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
determining that the first default configurations have been changed to the second default configurations, wherein the second default configurations are obtained in response to the determination.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
determining to restore the customized configurations stored at the first storage location to the customized configurations captured at the first restore time point;
retrieving the second difference stored at the second storage location in association with the first restore time point;
determining the configurations captured at the first restore time point based on the second configurations difference and the second default configurations; and
replacing the customized configurations stored at the first storage location with the customized configurations captured at the first restore time point.

### Claim 7

An apparatus, the apparatus being a thin client, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
capture, at a first restore time point, customized configurations of the thin client stored at a first storage location of the thin client;
obtain first default configurations of the thin client that are in use;
determine a first difference between the customized configurations and the first default configurations; and
store the first difference in association with the first restore time point at a second storage location of the thin client;
obtain second default configurations of the thin client that replaces the first default configurations;
determine a default configuration difference between the first default configurations and the second default configurations;
determine a second difference between the customized configurations and the second default configurations based on the first difference and the default configuration difference; and
replace the first difference stored at the second storage location in association with the first restore time point with the second difference.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein the at least one processor is further configured to:
capture, at each of a plurality of restore time points in addition to the first restore time point, respective customized configurations of the thin client stored at the first storage location;
determine a respective difference between the respective customized configurations at each of the plurality of restore time points and the first default configurations; and
