However, xperf clearly shows us that volsnap.sys constantly uses the disk. I suppose it stuck into some infinite loop or some. Recently my laptop started to become sluggish and the ventilators was constantly on. In task manager it was clear the system process…<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,55,73],"tags":[],"class_list":["post-2245","post","type-post","status-publish","format-standard","hentry","category-szakmai-elet","category-windows","category-winternals"],"_links":{"self":[{"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/posts\/2245","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/comments?post=2245"}],"version-history":[{"count":5,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/posts\/2245\/revisions"}],"predecessor-version":[{"id":2252,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/posts\/2245\/revisions\/2252"}],"wp:attachment":[{"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/media?parent=2245"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/categories?post=2245"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/soci.hu\/blog\/index.php\/wp-json\/wp\/v2\/tags?post=2245"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
\nVolsnap is the volume snapshot service, which supports backup and recovery. So, at first I stopped Volume Shadow Copy service. It did not help.
\nThen, I deleted<\/a> system restore points for my drives.
\nIt took several minutes to finish deleting old restore points. After a reset system process is now behave correctly.
\nSystem restore points are very important for certain scenarios, so be careful to turn it off. This is just a workaround, to clean up bogus system restore points.
\nAfter deletion and restart you should have to reenable it!
\nI re-enabled it, and the problem did not manifest again. So, I think deleting and recreating restore points solve this kind of weird problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
