Windows Forum / Windows XP / General Topics 1 / June 2008System Restore registry key missing
Two days ago I had read it was a good idea to occassionally run an online antivirus scan sort of as a second opinion to one you run installed on your computer so I ran the Kaspersky Online Scan which said it found three items. (Norton is installed on the machine and found nothing.) I sent three files to Kaspersky to evaluate and in the meanwhile I disabled and then enabled System Restore again. A restore point was created at that time by itself. After the fact I received an email from Kaspersky apologizing but it was a false result. Great. Now I lost all my previous restore points and it has not created a System Checkpoint since I enabled it again. I went to check the registry and from what I've read online there should be an entry determining checkpoint frequency "HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion \SystemRestore" but it's missing. Nothing. I have this one "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services \Sr" I also have this one "HKEY_LOCAL_MACHINE\System\CurrentControlSet \Services\Srservice" Is there some handy little vbs file or easy fix to get that registry key back again? Thank you- Vickie I did find a key in a different place HKEY_CURRENT_USER\Software \Microsoft\Windows NT\CurrentVersion\Windows\ Name: DisableSR Type: Reg_DWORD Data: 0X00000000 (0) Is this the same thing? I'm so upset over this. I've had no issues with System Restore for the 5 years I've had this system.

I Enabled System Restore yesterday morning, so it's been about 36 hours or so and no checkpoint. (It has faithfully made checkpoints just about every day for years.) There's no registry key for HKEY_LOCAL_MACHINE\Software\Microsoft \WindowsNT\CurrentVersion \SystemRestore I'm worried there should be one there or I'll get no System Checkpoints now.

In other words if your computer is on six hours a day, it would be 4-5 days before a routine System Checkpoint would be created. Thank you for your reply.

My computer is usually on 24 hours a day. Vickie > Vickie - I made an error in my first reply - regarding > "... note that it is not 24 hours of operating time...." [quoted text clipped - 64 lines] > > - Show quoted text - Sorry, but that's incorrect. A new restore point will be created 24 hours after the previous one at a time when the computer is idle. It's 24 hours according to the clock, not how long the computer has been running. If you're looking for a reference, take a look at the Scheduled restore points section of this article. Microsoft Windows XP System Restore http://msdn.microsoft.com/en-us/library/ms997627.aspx#windowsxpsystemrestore_auto "In addition to creating restore points before certain events, System Restore provides users with the ability to restore to other specific days and times. It does this by creating a restore point every 24 hours of calendar time. By default, System Restore will create a restore point every day that the machine is running. These restore points are only created during idle time; for example, when there is no mouse, keyboard, or disk i/o activity."

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\SystemRestore You should find a value named RPGlobalInterval set to 86400 decimal under that key. If it's not there, you could try reinstalling System Restore. Take a look at this web site for more info. Courtesy of Bert Kinney, MS-MVP How to Reinstall System Restore in Windows XP http://bertk.mvps.org/html/reinstall.html Another approach would be to see if you can run the first .vbs file listed on this page. http://bertk.mvps.org/html/srscripts.html Good luck Nepatsfan Exactly. The whole key is missing. I'm pretty sure I remember the key existing years ago, (I've had no need to check it any time recently), but I'm not sure if I may have looked at the one in HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows \ I'll try the .vbs file first. Thank you- Vickie > > Two days ago I had read it was a good idea to occassionally run an > > online antivirus scan sort of as a second opinion to one you run [quoted text clipped - 51 lines] > > - Show quoted text - Boy am I a dummy. I didn't expand Current Version and scroll down to where System Restore is listed. I thought it was a value I should have seen simply by highlighting Current Version. OK, here are some values from the right side: Name: DisableSR Type: REG_DWORD Data: 0x00000000 (0) Name: Restore Status Type: REG_DWORD Data: 0x00000001 (1) Name: RPGlobalInterval Type: REG_DWORD Data: 0x00015180 (86400) Name: RPLifeInterval Type: REG_DWORD Data: 010076a700 (7776000) I think the values are set for System Restore to be Enabled and make a restore point every 86400 seconds (24 hours), is that right? What is the Restore Status for and the value of (1) mean? Are these set correctly?

A service can compress data for the amount of time that is specified in this value, and then stop. Then, at the next idle time compression, the computer can repeat the process. • DiskPercent This value relates to the percentage of disk space that System Restore uses for its data store. The default value is 12 percent. The data store size is always calculated as "max(12 percent, DSMax)," regardless of the size of the hard disk. The maximum (max) size is what is specified in DSMax. For hard disk sizes that are less than 4 gigabytes (GB) in size, 12 percent is less than 400 megabytes (MB), so "max(12 percent, DSMax) equals 400 MB." For hard disk sizes that are greater than 4 GB, 12 percent is greater than 400 MB, so "max(12 percent, DSMax) equals 12 percent." This data store size is not a reserved disk space, and the data store size is used only on demand. • DSMax This value specifies the maximum size for the System Restore data store. The default size of the data store is 400 MB. The data store size is always calculated as "max(12 percent, DSMax)," regardless of the size of the hard disk. The maximum (max) size is what is specified in DSMax. For hard disk sizes that are less than 4 GB, 12 percent is less than 400 MB, so "max(12 percent, DSMax) equals 400 MB." For hard disk sizes that are greater than 4 GB, 12 percent is greater than 400 MB, so "max(12 percent, DSMax) equals 12 percent." This data store size is not a reserved disk space, and the data store size is used only on demand. • DSMin This value relates to the minimum amount of free disk space that System Restore needs so that it can function during the installation process. Also, this value relates to the minimum amount of free disk space that is needed for System Restore to reactivate and to resume the creation of restore points after System Restore has been disabled because of low disk space. • RestoreStatus This value specifies if the last restore operation failed (0), succeeded (1), or had been interrupted (2). • RPGlobalInterval This value specifies, in seconds, the amount of time that System Restore waits before it creates the automatic computer check points for elapsed time. The default value is 24 hours. • RPLifeInterval This value specifies, in seconds, the restore points Time to Live (TTL). When a restore point reaches this time and it is still on the system, it gets deleted. The default value is (7776000), which will be 90 days. • RPSessionInterval This value specifies, in seconds, the amount of time that System Restore waits before it creates the automatic computer check points for session time (the amount of time that the computer has been on). The default value is zero (0), which means that this feature is turned off. • ThawInterval This value specifies, in seconds, the amount of time that System Restore waits before it activates itself from a disabled state (after the conditions for this process to occur have been met). If you start the System Restore user interface, System Restore is activated immediately. ----------------------------------------------------------------------------------- > Boy am I a dummy.

Here's the entire list of values under that registry key on a computer that has no problems creating automatic restore points. "DisableSR"=dword:00000000 "CreateFirstRunRp"=dword:00000001 "DSMin"=dword:000000c8 "DSMax"=dword:00000190 "RPSessionInterval"=dword:00000000 "RPGlobalInterval"=dword:00015180 "RPLifeInterval"=dword:0076a700 "CompressionBurst"=dword:0000003c "TimerInterval"=dword:00000078 "DiskPercent"=dword:0000000c "ThawInterval"=dword:00000384 "RestoreDiskSpaceError"=dword:00000000 "RestoreStatus"=dword:00000001 "RestoreSafeModeStatus"=dword:00000000 Keep in mind that the computer has to be idle for a reasonable amount of time for an automatic restore point to be created. If you turn your computer on and off all day, there might not be a window of opportunity for Windows to create a restore point. Here's a web site with some other things you can check.

Norton is known for knocking out the restore point.
